Specifying the pin number and flags, as defined + in <dt-bindings/gpio/gpio.h> + +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 + + sdc2_clk, sdc2_cmd, sdc2_data + Supports bias and drive-strength + + ufs_reset + Supports bias and drive-strength + +- function: + Usage: required + Value type: <string> + Definition: Specify the alternative function to be configured for the + specified pins.
