Each of these subnodes represents some desired configuration for a 69pin, a group, or a list of pins or groups. This configuration can include the 70mux function to select on those pin(s)/group(s), and various pin configuration 71parameters, such as pull-up, drive strength, etc. 72 73 74PIN CONFIGURATION NODES: 75 76The name of each subnode is not important; all subnodes should be enumerated 77and processed purely based on their content. 78 79Each subnode only affects those parameters that are explicitly listed. In 80other words, a subnode that lists a mux function but no pin configuration 81parameters implies no information about any pin configuration parameters. 82Similarly, a pin subnode that describes a pullup parameter implies no 83information about e.g. the mux function. 84 85 86The following generic properties as defined in pinctrl-bindings.txt are valid 87to specify in a pin configuration subnode: 88 89- pins: 90 Usage: required 91 Value type: <string-array> 92 Definition: List of gpio pins affected by the properties specified in 93 this subnode. 94 95 Valid pins are: 96 gpio0-gpio149 97 Supports mux, bias and drive-strength 98 99 sdc1_clk, sdc1_cmd, sdc1_data sdc2_clk, sdc2_cmd, 100 sdc2_data sdc1_rclk 101 Supports bias and drive-strength 102 103 ufs_reset 104 Supports bias and drive-strength 105 106- function: 107 Usage: required 108 Value type: <string> 109 Definition: Specify the alternative function to be configured for the 110 specified pins.
