     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
     14 *	to go into when returning from sleep and idle in
     15 *	.pm_runtime_resume() or ordinary .resume() for example.
     16 * @PINCTRL_STATE_INIT: normally the pinctrl will be set to "default"
     17 *	before the driver's probe() function is called.  There are some
     18 *	drivers where that is not appropriate becausing doing so would
     19 *	glitch the pins.  In those cases you can add an "init" pinctrl
     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
     26 *	example. Could typically be set from a pm_runtime_suspend() or
     27 *	pm_runtime_idle() operation.
     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
     31 *	ordinary .suspend() function.
