		Qualcomm Technologies, Inc. WCD GPIO block

		This binding describes the GPIO block found in the WCD934X series of
		audio codec's from QTI.

		- compatible:
		Usage: required
		Value type: <string>
		Definition: must be "qcom,wcd-pinctrl"

		- qcom,num-gpios:
		Usage: required
		Value type: <u32>
		Definition: Number of GPIO's supported by the controller

		- gpio-controller:
		Usage: required
		Value type: <none>
		Definition: Mark the device node as a GPIO controller

		- #gpio-cells:
		Usage: required
		Value type: <u32>
		Definition: Must be 2;
		the first cell will be used to define gpio number and the
		second denotes the flags for this gpio

		Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.

		Please refer to pinctrl-bindings.txt in this directory for details of the
		common pinctrl bindings used by client devices, including the meaning of the
		phrase "pin configuration node".

		The pin configuration nodes act as a container for an arbitrary number of
		subnodes. Each of these subnodes represents some desired configuration for a
		pin or a list of pins. This configuration can include the
		mux function to select on those pin(s), and various pin configuration
		parameters, as listed below.


		SUBNODES:

		The name of each subnode is not important; all subnodes should be enumerated
		and processed purely based on their content.

		Each subnode only affects those parameters that are explicitly listed. In
		other words, a subnode that lists a mux function but no pin configuration
		parameters implies no information about any pin configuration parameters.
		Similarly, a pin subnode that describes a pullup parameter implies no
		information about e.g. the mux function.

		The following generic properties as defined in pinctrl-bindings.txt are valid
		to specify in a pin configuration subnode:

		- pins:
		Usage: required
		Value type: <string-array>
		Definition: List of gpio pins affected by the properties specified in
		this subnode. Valid pins are:
		gpio1-gpio5 for wcd9340

		- bias-disable:
		Usage: optional
		Value type: <none>
		Definition: The specified pins should be configured as no pull.

		- bias-pull-down:
		Usage: optional
		Value type: <none>
		Definition: The specified pins should be configured as pull down.

		- bias-pull-up:
		Usage: optional
		Value type: <empty>
		Definition: The specified pins should be configured as pull up.

		- qcom,pull-up-strength:
		Usage: optional
		Value type: <u32>
		Definition: Specifies the strength to use for pull up, if selected.

		- bias-high-impedance:
		Usage: optional
		Value type: <none>
		Definition: The specified pins will put in high-Z mode and disabled.

		- input-enable:
		Usage: optional
		Value type: <none>
		Definition: The specified pins are put in input mode.

		- output-high:
		Usage: optional
		Value type: <none>
		Definition: The specified pins are configured in output mode, driven
		high.

		- output-low:
		Usage: optional
		Value type: <none>
		Definition: The specified pins are configured in output mode, driven
		low.

		- qcom,drive-strength:
		Usage: optional
		Value type: <u32>
		Definition: Selects the drive strength for the specified pins.

		Example:

		wcd: wcd_pinctrl@5 {
		compatible = "qcom,wcd-pinctl";
		qcom,num-gpios = <5>
		gpio-controller;
		#gpio-cells = <2>;

		spkr_1_wcd_en_active: spkr_1_wcd_en_active {
		mux {
		pins = "gpio2";
		};

		config {
		pins = "gpio2";
		output-high;
		};
		};

		spkr_1_wcd_en_sleep: spkr_1_wcd_en_sleep {
		mux {
		pins = "gpio2";
		};

		config {
		pins = "gpio2";
		input-enable;
		};
		};
		};
