		Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
		a general description of GPIO and interrupt 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, a group, or a list of pins or groups. This configuration can include the
		mux function to select on those pin(s)/group(s), and various pin configuration
		parameters, such as pull-up, drive strength, etc.


		PIN CONFIGURATION NODES:

		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:
		gpio0-gpio155
		Supports mux, bias and drive-strength

		sdc1_clk, sdc1_cmd, sdc1_data sdc2_clk, sdc2_cmd,
		sdc2_data sdc1_rclk
		Supports bias and drive-strength

		function:
		Usage: required
		Value type: <string>
		Definition: Specify the alternative function to be configured for the
		specified pins. Functions are only valid for gpio pins.
