| * 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 |
| - qcom,wcnss-adc_tm: ADC handle for vbatt notification APIs. |
| |
| 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. |
| |
