| * Qualcomm WCNSS Platform Driver |
| |
| WCNSS driver is the platform driver. It is used for performing the cold |
| boot-up of the wireless device. It is responsible for adjusting |
| the necessary I/O rails and enabling appropriate gpios for wireless |
| connectivity subsystem. |
| |
| Required properties: |
| - compatible: "wcnss_wlan" |
| - reg: physical address and length of the register set for the device. |
| - reg-names: "wcnss_mmio", "wcnss_fiq", "pronto_phy_base", "riva_phy_base", |
| "riva_ccu_base", "pronto_a2xb_base", "pronto_ccpu_base", |
| "pronto_saw2_base", "wlan_tx_phy_aborts","wlan_brdg_err_source", |
| "wlan_tx_status", "alarms_txctl", "alarms_tactl", |
| "pronto_mcu_base". |
| - interupts: Pronto to Apps interrupts for tx done and rx pending. |
| - qcom,pronto-vddmx-supply: regulator to supply pronto pll. |
| - qcom,pronto-vddcx-supply: voltage corner regulator to supply WLAN/BT/FM |
| digital module. |
| - qcom,pronto-vddpx-supply: regulator to supply WLAN DAC. |
| - qcom,iris-vddxo-supply : regulator to supply RF XO. |
| - qcom,iris-vddrfa-supply : regulator to supply RFA digital. |
| - qcom,iris-vddpa-supply : regulator to supply RF PA. |
| - qcom,iris-vdddig-supply : regulator to supply RF digital(BT/FM). |
| - gpios: gpio numbers to configure 5-wire interface of WLAN connectivity |
| - qcom,has-48mhz-xo: boolean flag to determine the usage of 24MHz XO from RF |
| - qcom,has-pronto-hw: boolean flag to determine the revId of the WLAN subsystem |
| - qcom,wcnss-adc_tm: ADC handle for vbatt notification APIs. |
| - pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt |
| - pinctrl-names : Names corresponding to the numbered pinctrl states |
| - clocks: from common clock binding: handle to xo and rf_clk clocks. |
| - clock-names: Names of all the clocks that are accessed by the subsystem |
| |
| Optional properties: |
| - qcom,has-autodetect-xo: boolean flag to determine whether Iris XO auto detect |
| should be performed during boot up. |
| - qcom,wlan-rx-buff-count: WLAN RX buffer count is a configurable value, |
| using a smaller count for this buffer will reduce the memory usage. |
| - qcom,is-pronto-vt: boolean flag to determine the pronto hardware version |
| in use. subsequently Pronto and IRIS voltage regulator range is configured |
| according to the ponto HW version |
| - qcom,is-pronto-v3: boolean flag to determine the pronto hardware version |
| in use. subsequently correct workqueue will be used by DXE engine to push frames |
| in TX data path and correct voting to RPM will be decided for booting. |
| - qcom,wcnss-pm : <Core rail LDO#, PA rail LDO#, XO settling time, |
| RPM power collapse enabled, standalone power collapse enabled> |
| Power manager related parameter for LDO configuration. |
| 11 - WCN CORE rail LDO number |
| 21 - WCN PA rail LDO number |
| 1200 - WCN XO settling time (usec) |
| 1 - WCN RPM power collapse enabled |
| 1 - WCN standalone power collapse enabled |
| 6 - GPIO strength value |
| |
