The contents of each of those pin configuration child nodes is defined entirely by the binding for the individual pin controller device. There exists no common standard for this content. The pinctrl framework only provides generic helper bindings that the pin controller driver can use. The pin configuration nodes need not be direct children of the pin controller device; they may be grandchildren, for example. Whether this is legal, and whether there is any interaction between the child and intermediate parent nodes, is again defined entirely by the binding for the individual pin controller device. properties: $nodename: pattern: "^(pinctrl|pinmux)(@[0-9a-f]+)?$" "#pinctrl-cells": description: > Number of pin control cells in addition to the index within the pin controller device instance. pinctrl-use-default: type: boolean description: > Indicates that the OS can use the boot default pin configuration. This allows using an OS that does not have a driver for the pin controller. This property can be set either globally for the pin controller or in child nodes for individual pin group control. additionalProperties: true
