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: + Definition: List of gpio pins affected by the properties specified in + this subnode. + + Valid pins are: + gpio0-gpio118 + 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 + + ufs_reset + Supports bias and drive-strength + +- function: + Usage: required + Value type: + Definition: Specify the alternative function to be configured for the + specified pins.
