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: + Definition: List of gpio pins affected by the properties specified in + this subnode. + + Valid pins: + 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: + Definition: Specify the alternative function to be configured for the + specified pins.
