* Qualcomm Technologies Inc. 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", "pronto_qfuse".

- 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

iris and pronto regulators in micro-amps.

Optional properties:

- qcom,has-autodetect-xo: boolean flag to determine whether Iris XO auto detect

should be performed during boot up.

- qcom,snoc-wcnss-clock-freq: indicates the wcnss snoc clock frequency in Hz.

If wcnss_snoc clock is specified in the list of clocks, this property needs

to be set to make it functional.

- 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-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.

- qcom,is-dual-band-disable: boolean flag to determine the WLAN dual band

capability.

- qcom,is-pronto-vadc: boolean flag to determine Battery voltage feature

support for pronto hardware.

- 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

- qcom,has-vsys-adc-channel: boolean flag to determine which ADC HW channel need

to use for VBATT feature.

- qcom,has-a2xb-split-reg: boolean flag to determine A2xb split timeout limit

register is available or not.

	  The driver will help route diag traffic from modem side over the QDSS

	  sub-system to USB on APSS side. The driver acts as a bridge between the

	  MHI and USB interface. If unsure, say N.

	help

	 When Apps receives a WDOG bite from WCNSS, collecting a register dump

	 of WCNSS is helpful to root cause the failure. WCNSS may not be

	 properly clocked in some WCNSS bite cases, and that may cause unclocked

	 register access failures. So this feature is to enable/disable the

	 register dump on WCNSS WDOG bite.

	  Add crypto support for the WLAN  driver module.

	  This feature enable wlan driver to use the crypto APIs exported
