5     The nRF pin controller is a singleton node responsible for controlling
6     pin function selection and pin properties. For example, you can use this
7     node to route UART0 RX to pin P0.1 and enable the pull-up resistor on the
8     pin.
17     All device pin configurations should be placed in child nodes of the
20       /* You can put this in places like a board-pinctrl.dtsi file in
33             /* configure P0.3 as UART_RX and P0.4 as UART_CTS */
34             psels = <NRF_PSEL(UART_RX, 0, 3)>, <NRF_PSEL(UART_CTS, 0, 4)>;
35             /* both P0.3 and P0.4 are configured with pull-up */
36             bias-pull-up;
41     The 'uart0_default' child node encodes the pin configurations for a
43     state. You would specify the low-power configuration for the same device
46     As shown, pin configurations are organized in groups within each child node.
47     Each group can specify a list of pin function selections in the 'psels'
48     property. The NRF_PSEL macro is used to specify a pin function selection.
49     If a pin needs to be explicitly disconnected, there is also the
51     Available pin functions can be found in the
52     include/zephyr/dt-bindings/pinctrl/nrf-pinctrl.h header file.
54     A group can also specify shared pin properties common to all the specified
55     pins, such as the 'bias-pull-up' property in group 2. Here is a list of
56     supported standard pin properties:
58     - bias-disable: Disable pull-up/down (default behavior, not required).
59     - bias-pull-up: Enable pull-up resistor.
60     - bias-pull-down: Enable pull-down resistor.
61     - low-power-enable: Configure pin as an input with input buffer
66     To link this pin configuration with a device, use a pinctrl-N property
70        #include "board-pinctrl.dtsi"
73              pinctrl-0 = <&uart0_default>;
74              pinctrl-names = "default";
