- A pinctrl node should contain at least one subnodes representing the
- pinctrl groups available on the machine. Each subnode will list the
- pins it needs, and how they should be configured, with regard to muxer
- configuration, pullups, drive strength, input enable/disable and
- input schmitt.
- An example of using macro:
- pincontroller {
- /* GPIO0 set as multifunction GPIO0 */
- state_0_node_a {
- pinmux = <PINMUX_GPIO0__FUNC_GPIO0>;
- };
- /* GPIO1 set as multifunction PWM */
- state_0_node_b {
- pinmux = <PINMUX_GPIO1__FUNC_PWM_1>;
- };
- };

- Supported pin number and mux varies for different SoCs, and are defined
