5 The Ambiq Apollo4 pin controller is a node responsible for controlling
6 pin function selection and pin properties, such as routing a UART0 TX
19 /* You can put this in places like a board-pinctrl.dtsi file in
20 * your board directory, or a devicetree overlay in your application.
23 /* include pre-defined combinations for the SoC variant used by the board */
24 #include <dt-bindings/pinctrl/ambiq-apollo4-pinctrl.h>
33 input-enable;
38 The 'uart0_default' child node encodes the pin configurations for a
39 particular state of a device; in this case, the default (that is, active)
43 Each group can specify a list of pin function selections in the 'pinmux'
46 A group can also specify shared pin properties common to all the specified
47 pins, such as the 'input-enable' property in group 2.
