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
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

24       #include <dt-bindings/pinctrl/ambiq-apollo4-pinctrl.h>

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.
