There19 exists no common standard for this content. The pinctrl framework only20 provides generic helper bindings that the pin controller driver can use.21 22 The pin configuration nodes need not be direct children of the pin controller23 device; they may be grandchildren, for example. Whether this is legal, and24 whether there is any interaction between the child and intermediate parent25 nodes, is again defined entirely by the binding for the individual pin26 controller device.27 28properties:29 $nodename:30 pattern: "^(pinctrl|pinmux)(@[0-9a-f]+)?$"31 32 "#pinctrl-cells":33 description: >34 Number of pin control cells in addition to the index within the pin35 controller device instance.36 37 pinctrl-use-default:38 type: boolean39 description: >40 Indicates that the OS can use the boot default pin configuration.
