* Qualcomm Connectivity SubSystem Platform Driver
|
|
|
|
This platform driver adds support for the CNSS subsystem used for SDIO
|
|
based Wi-Fi devices. It also adds support to manage two 1.8V voltage
|
|
regulators and WLAN power enable 3.3V regulators. The main purpose of this
|
|
device tree entry below is to invoke the CNSS SDIO platform driver
|
|
and provide handle to the WLAN power enable 3.3V pmic GPIO and two 1.8V
|
|
PMIC voltage regulator resources.
|
|
|
|
Required properties:
|
|
- compatible: "qcom,cnss_sdio"
|
|
- reg: memory resource to save firmware dump, optional.
|
|
- reg-names: memory resource name.
|
|
- subsys-name: cnss sdio subsytem device name, required.
|
|
- vdd-wlan-supply: phandle to the WLAN vdd regulator device tree node.
|
|
- vdd-wlan-dsrc-supply: phandle to the WLAN dsrc vdd regulator device tree node.
|
|
- vdd-wlan-io-supply: phandle to the WLAN IO regulator device tree node.
|
|
- vdd-wlan-xtal-supply: phandle to the WLAM XTAL regulator device tree node.
|
|
|
|
Example:
|
|
qcom,cnss-sdio {
|
|
compatible = "qcom,cnss_sdio";
|
|
reg = <0x87a00000, 0x200000>;
|
|
reg-names = "ramdump";
|
|
subsys-name = "AR6320";
|
|
vdd-wlan-supply = <&rome_vreg>;
|
|
vdd-wlan-dsrc-supply = <&sdcard_ext_vreg>;
|
|
vdd-wlan-io-supply = <&mdm9607_l11>;
|
|
vdd-wlan-xtal-supply = <&mdm9607_l2>;
|
|
};
