| bool "External SOCs Control" |
| help |
| External SOCs can be powered on and monitored by user |
| space or kernel drivers. Additionally they can be controlled |
| to respond to control commands. This framework provides an |
| interface to track events related to the external slave socs. |

| config ESOC_DEV |
| bool "ESOC userspace interface" |
| help |
| Say yes here to enable a userspace representation of the control |
| link. Userspace can register a request engine or a command engine |
| for the external soc. It can receive event notifications from the |
| control link. |
| |
| config ESOC_CLIENT |
| bool "ESOC client interface" |
| depends on OF |
| help |
| Say yes here to enable client interface for external socs. |
| Clients can specify the external soc that they are interested in |
| by using device tree phandles. Based on this, clients can register |
| for notifications from a specific soc. |
| |
| config ESOC_DEBUG |
| bool "ESOC debug support" |
| help |
| Say yes here to enable debugging support in the ESOC framework |
| and individual esoc drivers. The config basically adds extra |
| logging information such that, in the event of a bug, this |
| logging information could be helpful to trace it. |
| |
| config ESOC_MDM_4x |
| bool "Add support for external modems" |
| help |
| In some qualcomm boards, an external modem such as mdm9x55 or sdx50m |
| is connected to a primary msm. The primary soc can control/monitor |
| the modem via gpios. The data communication with such modems can |
| occur over PCIE or HSIC. |
| |
| config ESOC_MDM_DRV |
| tristate "Command engine for 4x series external modems" |
| help |
| Provides a command engine to control the behavior of an external |
| modems (such as mdm9x55 or sdx50m). That is, it extends the SSR |
| framework to power-off, power-on or handle crash scenarios. It |
| also listens for events on the external modem. |
| |
| config ESOC_MDM_DBG_ENG |
| tristate "debug engine for 4x series external modems" |
| depends on ESOC_MDM_DRV |
| help |
| Mainly used as a debug interface to probe the modem against various |
| scenarios. It basically provides a user interface to mask out certain |
| commands sent by command engine to the external modem. It also allows |
| masking of certain notifications being sent to the external modem. |
| |
| config MDM_DBG_REQ_ENG |
| tristate "manual request engine for 4x series external modems" |
| depends on ESOC_MDM_DBG_ENG |
| help |
| Provides a user interface to handle incoming requests from |
| the external modem. Allows for debugging of IPC mechanism |
| between the external modem and the primary soc. |
