39 The only exception is that no bus will be created for a state named "idle". If
40 such a state is defined, it must be the last entry in pinctrl-names. For

50 If an idle state is defined, whenever an access is not being made to a device
51 on a child bus, the idle pinctrl state will be programmed into hardware.
