10  * @PINCTRL_STATE_DEFAULT: the state the pinctrl handle shall be put
11  *	into as default, usually this means the pins are up and ready to
12  *	be used by the device driver. This state is commonly used by
13  *	hogs to configure muxing and pins at boot, and also as a state
16  * @PINCTRL_STATE_INIT: normally the pinctrl will be set to "default"
20  *	which is the state of the pins before drive probe.  After probe
21  *	if the pins are still in "init" state they'll be moved to
22  *	"default".
23  * @PINCTRL_STATE_IDLE: the state the pinctrl handle shall be put into
24  *	when the pins are idle. This is a state where the system is relaxed
25  *	but not fully sleeping - some power may be on but clocks gated for
28  * @PINCTRL_STATE_SLEEP: the state the pinctrl handle shall be put into
29  *	when the pins are sleeping. This is a state where the system is in
30  *	its lowest sleep state. Could typically be set from an
