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-gpio145 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.
