5   The Ambiq Apollo3 pin controller is a node responsible for controlling
6   pin function selection and pin properties, such as routing a UART0 TX
7   to pin 60 and enabling the pullup resistor on that pin.
16   All device pin configurations should be placed in child nodes of the
19   /* You can put this in places like a board-pinctrl.dtsi file in
23   /* include pre-defined combinations for the SoC variant used by the board */
24   #include <dt-bindings/pinctrl/ambiq-apollo3-pinctrl.h>
33         input-enable;
38   The 'uart0_default' child node encodes the pin configurations for a
42   As shown, pin configurations are organized in groups within each child node.
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.
