* 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"
|
||
|
|
- interupts: Pronto to Apps interrupts for tx done and rx pending.
|
||
|
|
- qcom,pronto-vddmx-supply: regulator to supply pronto pll.
|
||
|
|
- qcom,pronto-vddcx-supply: 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
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
