5   The Nuvoton pin controller is a singleton node responsible for controlling
6   pin function selection and pin properties. For example, you can use these
7   nodes to select peripheral pin functions.
9   Here is a list of supported standard pin properties:
10     - bias-pull-down: Enable pull-down resistor.
11     - bias-pull-up: Enable pull-up resistor.
12     - drive-open-drain: Output driver is open-drain.
14   Custom pin properties for npcx series are available also:
15     - pinmux-locked: Lock pinmux configuration for peripheral device
16     - pinmux-gpio: Inverse pinmux back to gpio
17     - psl-in-mode: Select the assertion detection mode of PSL input
18     - psl-in-pol: Select the assertion detection polarity of PSL input
23     #include <nuvoton/npcx/npcx7/npcx7-pinctrl.dtsi>
26   internal 3.3V pull-up if its i2c frequency won't exceed 400kHz.
28   To change a pin's pinctrl default properties, add a reference to the
29   pin in the board's DTS file and set the properties as below:
32       bias-pull-up; /* Enable internal pull-up for i2c0_0 */
33       pinmux-locked; /* Lock pinmuxing */
37       pinctrl-0 = <&i2c0_0_sda_scl_gpb4_b5>;
38       pinctrl-names = "default";
