6     Microchip XEC Pin controller Node
7     Based on pincfg-node.yaml binding.
8     The MCHP XEC pin controller is a singleton node responsible for controlling
9     pin function selection and pin properties. For example, you can use this
10     node to select peripheral pin functions.
19     All device pin configurations should be placed in child nodes of the
22     A group can also specify shared pin properties common to all the specified
23     pins, such as the 'bias-pull-up' property in group 2. Here is a list of
24     supported standard pin properties:
26     - bias-disable: Disable pull-up/down (default behavior, not required).
27     - bias-pull-down: Enable pull-down resistor.
28     - bias-pull-up: Enable pull-up resistor.
29     - drive-push-pull: Output driver is push-pull (default, not required).
30     - drive-open-drain: Output driver is open-drain.
31     - output-high: Set output state high when pin configured.
32     - output-low: Set output state low when pin configured.
34     Custom pin properties for drive strength and slew rate are available:
35     - drive-strength
36     - slew-rate
38     Driver strength and slew rate hardware defaults vary by SoC and pin.

46     and want the chip select 0 to be open-drain.
48     To change a pin's pinctrl default properties add a reference to the
49     pin in the board's DTS file and set the properties.

121         is "1x" for most pins. PIO pins are 2, 4, 8, or 12 mA. PIO-24 pins
122         are 4, 8, 16, or 24 mA. Please refer to the data sheet for each
123         pin's PIO type and default drive strength.
