14   Pin controller devices should contain the pin configuration nodes that client
17   The contents of each of those pin configuration child nodes is defined
18   entirely by the binding for the individual pin controller device. There
20   provides generic helper bindings that the pin controller driver can use.
22   The pin configuration nodes need not be direct children of the pin controller
25   nodes, is again defined entirely by the binding for the individual pin
26   controller device.
30     pattern: "^(pinctrl|pinmux)(@[0-9a-f]+)?$"
32   "#pinctrl-cells":
34       Number of pin control cells in addition to the index within the pin
35       controller device instance.
37   pinctrl-use-default:
40       Indicates that the OS can use the boot default pin configuration. This
41       allows using an OS that does not have a driver for the pin controller.
42       This property can be set either globally for the pin controller or in
43       child nodes for individual pin group control.
