+ION Memory Manager (ION)
+
+ION is a memory manager that allows for sharing of buffers between different
+processes and between user space and kernel space. ION manages different
+memory spaces by separating the memory spaces into "heaps". Depending on the
+type of heap ION must reserve memory using the msm specific memory reservation
+bindings (see Documentation/devicetree/bindings/arm/msm/memory-reserve.txt).
+
+Required properties
+
+- compatible: "qcom,msm-ion"
+- reg: The ID of the ION heap.
+
+Optional properties
+
+- compatible: "qcom,msm-ion-reserve" This is required if memory is to be reserved
+ as specified by qcom,memory-reservation-size below.
+- qcom,heap-align: Alignment of start of the memory in the heap.
+- qcom,heap-adjacent: ID of heap this heap needs to be adjacent to.
+- qcom,memory-reservation-size: size of reserved memory for the ION heap.
+- qcom,memory-reservation-type: type of memory to be reserved

+Qualcomm QPNP PWM/LPG controller
+
+qpnp-pwm driver supports Pulse Width Module (PWM) functionality. PWM feature is
+used in range of applications such as varying Display brightness, LED dimming,
+etc. The Qualcomm PMICs have a physical device called Light Pulse Generator
+(LPG). In addition to support PWM functionality, the LPG module provides
+a rich set of user defined PWM pattern configurations, such as sawtooth, linear
+up, linear down, triangular patterns etc. The PWM patterns are used in
+applications such as charger driver where the driver uses these patterns
+to indicate various states of charging.
+
+Required device bindings:
+- compatible: should be "qcom,qpnp-pwm"
+- reg: Offset and length of the controller's LPG channel register,
+ and LPG look-up table (LUT). The LPG look-up table is a
+ contiguous address space that is populated with PWM values.
+ The size of PWM value is 9 bit and the size of each
+ entry of the table is 8 bit. Thus, two entries are used
+ to fill each PWM value. The lower entry is used for PWM
+ LSB byte and higher entry is used for PWM MSB bit.
+- reg-names: Names for the above registers.
+ "qpnp-lpg-channel-base" = physical base address of the
+ controller's LPG channel register.
+ "qpnp-lpg-lut-base" = physical base address of LPG LUT.
+- qcom,channel-id: channel Id for the PWM.
+
+Optional device bindings:
+- qcom,channel-owner: A string value to supply owner information.
+- qcom,mode-select: 0 = PWM mode
+ 1 = LPG mode
+If this binding is specified along with the required bindings of PWM/LPG then
+in addition to configure PWM/LPG the qpnp-pwm driver also enables the feature
+at the probe time. In the case where the binding is not specified the qpnp-pwm
+driver does not enable the feature. Also, it is considered an error to specify
+a particular mode using this binding but not the respective feature subnode.
+
+All PWM devices support both PWM and LPG features within the same device.
+To support each feature, there are some required and optional bindings passed
+through device tree.
+
+The PWM device can enable one feature (either PWM or LPG) at any given time.
+Therefore, the qpnp-pwm driver applies the last PWM or LPG feature configuration
+and enables that feature.
+
+Required bindings to support PWM feature:
+- qcom,period: PWM period time in microseconds.
+- qcom,duty: PWM duty time in microseconds.
+- label: "pwm"
+
+Required bindings to support LPG feature:
+The following bindings are needed to configure LPG mode, where a list of
+duty cycle percentages is populated. The size of the list cannot exceed
+the size of the LPG look-up table.
+
+- qcom,period: PWM period time in microseconds.
+- qcom,duty-percents: List of entries for look-up table
+- cell-index: Index of look-up table that should be used to start
+ filling up the duty-pct list. start-idx + size of list
+ cannot exceed the size of look-up table.
+- label: "lpg"
+
+
+Optional bindings to support LPG feature:
+- qcom,ramp-step-duration: Time (in ms) to wait before loading next entry of LUT
+- qcom,lpg-lut-pause-hi: Time (in ms) to wait once pattern reaches to hi
+ index.
+- qcom,lpg-lut-pause-lo: Time (in ms) to wait once pattern reaches to lo
+ index.
+- qcom,lpg-lut-ramp-direction: 1 = Start the pattern from lo index to hi index.
+ 0 = Start the pattern from hi index to lo index.
+- qcom,lpg-lut-pattern-repeat: 1 = Repeat the pattern after the pause once it
+ reaches to last duty cycle.
+ 0 = Do not repeat the pattern.
+- qcom,lpg-lut-ramp-toggle: 1 = Toggle the direction of the pattern.
+ 0 = Do not toggle the direction.
+- qcom,lpg-lut-enable-pause-hi: 1 = Enable pause time at hi index.
+ 0 = Disable pause time at hi index.
+- qcom,lpg-lut-enable-pause-lo: 1 = Enable pause time at lo index.
+ 0 = Disable pause time at lo index.
+

+ };
+ };
+ };
+
+There are couple of ways to configure PWM device channels as shown in above
+example,
+1. The PWM device channel #0 is configured with only required device bindings.
+In this case, the qpnp-pwm driver does not configure any mode by default.
+
+2. The qpnp-pwm driver configures PWM device channel #1 with PWM feature
+configuration, but does not enable the channel since "qcom,mode-select" binding
+is not specified in the devicetree.
+
+3. Both the PWM and LPG configurations are provided for PWM device channel #4.
+The qpnp-pwm driver configures both the modes, but enables PWM mode at the probe
+time. It also sets the channel owner information for the channel.

+Introduction
+============
+
+In MDM9x25, new NAND controller(NANDc) has been added and it has the
+following major changes as compared to its previous version -
+
+1. It includes Secured BAM-Lite and the support for ADM(Application Data Mover)
+has been removed.
+
+2. It includes 4 bit BCH ECC and the support for 4 bit Reed Solomon ECC has
+been removed.
+
+3. The support for Dual NAND controllers has been removed and thus the
+software features like ping-pong mode and interleave mode are deprecated.
+
+4. It includes support for dual buffers in case of read and one dedicated
+write buffer to each processor (Modem and Apps).
+
+This new NAND driver takes care of all the above new hardware changes. In
+addition to the above hardware changes, it also takes care of software device
+tree changes.
+
+Hardware description
+====================
+
+The NANDc Core:
+---------------
+Qualcomm Parallel Interface Controller (QPIC), formerly named EBI2, is a
+wrapper module which integrates a NAND controller core and a LCD controller
+core and multiplexes their access to shared parallel interfaces pins. Both
+controller cores are accessible to processors (Modem and Apps), and share
+master access to the Peripheral NoC (Network on Chip) via a BAM module.
+
+In MDM9x25, QPIC is located on the peripheral NoC, connected via a 32-bit AHB
+Master port and a 32-bit AHB Slave Port. The NANDc register interface goes
+through AHB Slave Port and data transfers using BAM goes through AHB Master
+Port. The NAND Controller (NANDc) is a hardware core which manages the access
+to an off-chip NAND device.
+
+BAM-Lite:
+---------
+BAM(Bus Access Manager) can transfer data between a peripheral and memory,
+or between two peripherals in a BAM to BAM mode. Each BAM contains multiple
+DMA channels, called pipes. A pipe provides a unidirectional data transfer
+engine, capable of either receiving data in consumer mode, or transmitting
+data in producer mode. The consumer fetches the data from the source system
+memory, and the producer writes data to the destination system memory.
+
+BAM-Lite's interface is similar to the BAM interface with slight changes to
+the sideband interface. BAM-Lite is an area-optimized version of BAM. BAM-Lite
+supports new features such as Notify-When-Done(NWD), pipe lock/unlock and
+command descriptors.
+
+NANDc has a secured BAM-Lite which provides DMA support for the NANDc and
+command support for accessing the NANDc registers. It is called secured
+because it has an integrated APU (Address Protection Unit) that validates
+every access to BAM and its peripheral registers.
+
+The NANDc has in total 6 BAM pipes - 3 pipes are dedicated for each processor
+(Modem and Apps) at the hardware level.
+
+Software description
+====================
+
+The NAND device is shared between two independent file systems, each running
+on a different processor - the application processor (Apps) and the Modem.
+The NAND driver uses BAM driver to transfer NAND operation requests and
+data to/from the NAND Controller (NANDc) core through the BAM pipes. Every
+NANDc register read/write access must go through BAM as it facilitates security
+mechanisms to enable simultaneous access to NAND device from both processors
+(Modem and Apps).
+
+The Apps NAND driver registers NANDc BAM peripheral with BAM driver, allocates
+endpoints and descriptor FIFO memory and registers for complete event
+notification for the following pipes:
+
+ - system consumer pipe for data (pipe#0) : This BAM pipe will be used
+ for transferring data from system memory to NANDc i.e., during write.
+
+ - system producer pipe for data (pipe#1) : This BAM pipe will be used
+ for transferring data from NANDc to system memory i.e., during read.
+
+ - system consumer pipe for commands (pipe#2) : This BAM pipe will be
+ used for both reading and writing to NANDc registers. It can be
+ configured either as consumer pipe or producer pipe but as per HW
+ team's recommendation it is configured as consumer pipe.
+
+Control path:
+-------------
+Each NAND operation can be described as a set of BAM command or/and data
+descriptors.
+
+A command descriptor(CD) points to the starting address of a command
+block. Each command block may contain a set of command elements where
+each command element is a single NANDc register read/write. The NAND
+driver submits all command descriptors to its system consumer pipe#2.
+
+Data path:
+----------
+A Data Descriptor(DD) points to the start of a data block which is a sequential
+chunk of data.
+
+For page write operations, the NAND driver submits data descriptors to system
+consumer pipe#0 and as per the descriptors submitted, the BAM reads data from
+the data block into the NANDc buffer.
+
+For page read operations, the NAND driver submits data descriptors to system
+producer pipe#1 and as per the descriptors submitted, the BAM reads data from
+the NANDc buffer into the data block.
+
+The driver submits a CD/DD using BAM driver APIs sps_transfer_one()/
+sps_transfer(). To this API, flags is passed as one of the arguments and if
+SPS_IOVEC_FLAG_CMD is passed, then it is identified as a CD. Otherwise, it is
+identified as a DD. The other valid SPS flags for a CD/DD are -
+
+ - SPS_IOVEC_FLAG_INT : This flag indicates BAM driver to raise BAM
+ interrupt after the current descriptor with this flag has been
+ processed by BAM HW. This flag is applicable for both CD and DD.
+
+ - SPS_IOVEC_FLAG_NWD : This flag indicates BAM HW to not process
+ next descriptors until it receives an acknowledgement by NANDc
+ that the current descriptor with this flag is completely
+ executed. This flag is applicable only for a CD.
+
+ - SPS_IOVEC_FLAG_LOCK: This flag marks the beginning of a series of
+ commands and it indicates that all the CDs submitted on this pipe
+ must be executed atomically without any interruption by commands
+ from other pipes. This is applicable only for a CD.
+
+ - SPS_IOVEC_FLAG_UNLOCK: This flag marks the end of a series of
+ commands and it indicates that the other pipe that was locked due to
+ SPS_IOVEC_FLAG_LOCK flag can be unblocked after the current CD
+ with this flag is executed. This is applicable only for a CD.
+
+ - SPS_IOVEC_FLAG_EOT - This flag indicates to BAM driver that the
+ current descriptor with this flag is the last descriptor submitted
+ during write operation. This is applicable only for a DD.
+
+Error handling:
+---------------
+After a page read/write complete notification from BAM, NAND driver validates
+the values read from NANDc registers to confirm the success/failure of page
+read/write operation. For example, after a page read/write is complete, the
+drivers reads the NANDc status registers to check for any operational errors,
+protection violation errors and device status errors, number of correctable/
+uncorrectable errors reported by the controller. Based on the error conditions
+that are met, the driver reports appropriate error codes to upper layers. The
+upper layers respond to these errors and take appropriate action.
+
+Design
+======
+
+The existing NAND driver (ADM based) can not be reused due to many major HW
+changes (see Introduction section) in the new NANDc core. Some of the complex
+features (Dual NAND controllers support) too are deprecated in the new NANDc.
+Hence, a new NAND driver is written to take care of both SPS/BAM changes and
+other controller specific changes. The rest of the interaction with MTD and
+YAFFS2 remains same as its previous version of NAND driver msm_nand.c.
+
+Power Management
+================
+
+Two clocks are supplied by the system's clock controller to NANDc - AHB clock
+and interface clock. The interface clock is the clock that drives some of the
+HW blocks within NANDc. As of now, both these clocks are always on. But NANDc
+provides clock gating if some of the QPIC clock control registers are
+configured. The clock gating is yet to be enabled by driver.
+
+SMP/Multi-Core
+==============
+
+The locking mechanism for page read/write operations is taken care of by the
+higher layers such as MTD/YAFFS2 and only one single page operation can happen
+at any time on a given partition. For a single page operation, there is always
+only one context associated within the driver and thus no additional handling
+is required within the driver. But it is possible for file system to issue
+one request on partition and at the same time to issue another request on
+another partition as each partition corresponds to different MTD block device.
+This situation is handled within the driver by properly acquiring a mutex lock
+before submitting any command/data descriptors to any of the BAM pipes.
+
+
+Security
+========
+
+The same NAND device is accessible from both processors (Modem and Apps) and
+thus to avoid any configuration overwrite issues during a page operation,
+driver on each processor (Modem and Apps) must explicitly use BAM pipe
+lock/unlock mechanism. This is taken care of by the NAND driver. The partition
+violation issues are prevented by an MPU (Memory Protection Unit) that is
+attached to NANDc.
+
+Performance
+===========
+
+None.
+
+Interface
+=========
+
+The NAND driver registers each partition on NAND device as a MTD block device
+using mtd_device_register(). As part of this registration, the following ops
+(struct mtd_info *mtd) are registered with MTD layer for each partition:
+
+mtd->_block_isbad = msm_nand_block_isbad;
+mtd->_block_markbad = msm_nand_block_markbad;
+mtd->_read = msm_nand_read;
+mtd->_write = msm_nand_write;
+mtd->_read_oob = msm_nand_read_oob;
+mtd->_write_oob = msm_nand_write_oob;
+mtd->_erase = msm_nand_erase;
+
+msm_nand_block_isbad() - This checks if a block is bad or not by reading bad
+block byte in the first page of a block. A block is considered as bad if bad
+block byte location contains any value other than 0xFF.
+
+msm_nand_block_markbad() - This marks a block as bad by writing 0 to the
+entire first page of the block and thus writing 0 to bad block byte location.
+
+msm_nand_read/write() - This is used to read/write only main data from/to
+single/multiple pages within NAND device. The YAFFS2 file system can send
+read/write request for two types of data -
+
+ - Main data : This is the actual data to be read/written from/to a
+ page during a read/write operation on this device. The size of this
+ data request is typically based on the page size of the device
+ (2K/4K).
+
+ - OOB(Out Of Band) data : This is the spare data that will be used by
+ file system to keep track of its meta data/tags associated with the
+ actual data. As of now, the file system needs only 16 bytes to
+ accommodate this data. The NAND driver always writes this data
+ towards the end of main data.
+
+It is up to the file system whether or not to send a read/write request for OOB
+data along with main data.
+
+msm_nand_read_oob()/write_oob() - This is used to read/write both main data
+and spare data from/to single/multiple pages within NAND device.
+
+msm_nand_erase() - This erases the complete block by sending erase command to
+the device.
+
+The YAFFS2 file system registers as the user of MTD device and uses the ops
+exposed by the NAND driver to perform read/write/erase operations on NAND
+device. As of now, the driver can work with only YAFFS2 file system. An
+attempt to use it with any other file system might demand additional changes
+in the driver.
+
+Driver parameters
+=================
+
+None.
+
+Config options
+==============
+
+The config option MTD_MSM_QPIC_NAND enables this driver.
+
+Dependencies
+============
+
+It depends on the following kernel components:
+
+- SPS/BAM driver
+- MTD core layer
+- To add necessary NANDc and BAM resources to .dts file
+
+It depends on the following non-kernel components:
+
+The partition information of the NAND device must be passed by Modem subsystem
+to Apps boot loader and Apps boot loader must update the .dts file
+with the partition information as per the defined MTD bindings.
+
+The detailed information on MTD bindings can be found at -
+Documentation/devicetree/bindings/mtd/msm_qpic_nand.txt
+
+User space utilities
+====================
+
+None.
+
+Other
+=====
+
+No changes other than device tree changes are anticipated.
+
+Known issues
+============
+
+None.
+
+To do
+=====
+
+The NANDc core supports clock gating and is not yet supported by the driver.

+Introduction
+--------------
+ksbridge is a simple misc device which bridges Kickstart application
+to HSIC h/w. Driver supports two instances, one instance for
+flash-less-boot/ram-dumps and other instance for EFS Sync.
+
+Initialization
+--------------
+Create two bridge instances and register for usb devices 0x9008 and
+0x9048/0x904C. Misc device name depends on the USB PID.
+For PID: 9008, misc device name is ks_bridge and for PID:9048/904C,
+misc device name is efs_bridge. After KS opens the misc device, IN
+URBs will be submitted to H/W; By default IN URBS are configured
+to 20.
+
+TX PATH
+-------
+Transmit path is very simple. Bridge driver will exposes write system
+call to kickstart. Data from write call will be put into a list and a
+work is scheduled to take the data from the list and write to HSIC.
+
+Functions:
+ksb_fs_write: System call invoked when kickstart writes the data
+ksb_tomdm_work: Work function which submits data to HSIC h/w.
+
+Data Structures:
+to_mdm_list: Data is stored in this list
+to_mdm_work: mapped to ksb_tomdm_work function
+
+RX PATH
+-------
+During initialization 20 IN URBs are submitted to hsic controller. In
+completion handler of each URB, buffer is de-queued and add to a list.
+Read function is woken-up. A new buffer is created and submitted to
+controller.
+
+Functions:
+ksb_fs_read: system call invoked by ks when it tries to read the data
+ksb_rx_cb: rx urb completion handler
+ksb_start_rx_work: function called during initialization.
+
+Data Structures:
+ks_wait_q: read system call will block on this queue until data is
+available or device is disconnected
+to_ks_list: data queued to this list by rx urb completion handler,
+later de-queued by read system call.

+ * This function is a "CDC Ethernet Networking Control Model" (CDC ECM)
+ * Ethernet link. The data transfer model is simple (packets sent and
+ * received over bulk endpoints using normal short packet termination),
+ * and the control model exposes various data and optional notifications.
+ *
+ * ECM is well standardized and (except for Microsoft) supported by most
+ * operating systems with USB host support. It's the preferred interop
+ * solution for Ethernet over USB, at least for firmware based solutions.
+ * (Hardware solutions tend to be more minimalist.) A newer and simpler
+ * "Ethernet Emulation Model" (CDC EEM) hasn't yet caught on.
+ *
+ * Note that ECM requires the use of "alternate settings" for its data
+ * interface. This means that the set_alt() method has real work to do,
+ * and also means that a get_alt() method is required.
+ *
+ * This function is based on USB CDC Ethernet link function driver and
+ * contains MSM specific implementation.

+ * This function is an RNDIS Ethernet port -- a Microsoft protocol that's
+ * been promoted instead of the standard CDC Ethernet. The published RNDIS
+ * spec is ambiguous, incomplete, and needlessly complex. Variants such as
+ * ActiveSync have even worse status in terms of specification.
+ *
+ * In short: it's a protocol controlled by (and for) Microsoft, not for an
+ * Open ecosystem or markets. Linux supports it *only* because Microsoft
+ * doesn't support the CDC Ethernet standard.
+ *
+ * The RNDIS data transfer model is complex, with multiple Ethernet packets
+ * per USB message, and out of band data. The control model is built around
+ * what's essentially an "RNDIS RPC" protocol. It's all wrapped in a CDC ACM
+ * (modem, not Ethernet) veneer, with those ACM descriptors being entirely
+ * useless (they're ignored). RNDIS expects to be the only function in its
+ * configuration, so it's no real help if you need composite devices; and
+ * it expects to be the first configuration too.
+ *
+ * There is a single technical advantage of RNDIS over CDC Ethernet, if you
+ * discount the fluff that its RPC can be made to deliver: it doesn't need
+ * a NOP altsetting for the data interface. That lets it work on some of the
+ * "so smart it's stupid" hardware which takes over configuration changes
+ * from the software, and adds restrictions like "no altsettings".
+ *
+ * Unfortunately MSFT's RNDIS drivers are buggy. They hang or oops, and
+ * have all sorts of contrary-to-specification oddities that can prevent
+ * them from working sanely. Since bugfixes (or accurate specs, letting
+ * Linux work around those bugs) are unlikely to ever come from MSFT, you
+ * may want to avoid using RNDIS on purely operational grounds.
+ *
+ * Omissions from the RNDIS 1.0 specification include:
+ *
+ * - Power management ... references data that's scattered around lots
+ * of other documentation, which is incorrect/incomplete there too.
+ *
+ * - There are various undocumented protocol requirements, like the need
+ * to send garbage in some control-OUT messages.
+ *
+ * - MS-Windows drivers sometimes emit undocumented requests.
+ *
+ * This function is based on RNDIS link function driver and
+ * contains MSM specific implementation.
