5     The SmartBond pin controller is a singleton node responsible for controlling
6     pin function selection and pin properties, such as routing a UART RX to pin
7     P1.8 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/smartbond-pinctrl.h>
27         /* configuration for uart device, default state */
36             /* route UART RX to P0.8 and enable pull-up */
38             bias-pull-up;
43     The 'uart0_default' child node encodes the pin configurations for a
44     particular state of a device; in this case, the default (that is, active)
47     As shown, pin configurations are organized in groups within each child node.
48     Each group can specify a list of pin function selections in the 'pinmux'
52     A group can also specify shared pin properties common to all the specified
53     pins, such as the 'bias-pull-up' property in group 2. Here is a list of
54     supported standard pin properties:
56     - bias-pull-up: Enable pull-up resistor.
57     - bias-pull-down: Enable pull-down resistor.
59     Note that bias options are mutually exclusive.
61     To link this pin configuration with a device, use a pinctrl-N property
65        #include "board-pinctrl.dtsi"
68              pinctrl-0 = <&uart_default>;
69              pinctrl-names = "default";
