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:
