Merge "qcom: wcd934x: add pinctrl driver for wcd934x"

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.
