 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 are:
 		      gpio0-gpio149
 		        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.
