* Qualcomm Atheros mobile chipsets

Required properties:
    - compatible: Can be "qca,ar6004-sdio" for SDIO device and
    "qca,ar6004-hsic" for HSIC device. For AR6003, "qca,ar6003-sdio" can be
    used.
    - qca,chip-pwd-l-gpios: specify GPIO for CHIP_PWD_L.

Optional Properties:
    - cell-index: WLAN Hardware index.
    - qca,pm-enable-gpios: Specify this GPIO if internal PMU needs to be used.
    - qca,vbatt-supply: Specify this if VBATT is provided through a regulator.
    - qca,vdd-io-supply: Specify this if VDD-IO is provided through a
    regulator.

Example:

	wlan0: qca,wlan {
		cell-index = <0>;
		compatible = "qca,ar6004-sdio";
		qca,chip-pwd-l-gpios = <&msmgpio 62 0>;
		qca,pm-enable-gpios = <&pm8019_gpios 3 0x0>;
		qca,vdd-io-supply = <&pm8019_l11>;
	};
