+/**
+ * @PINCTRL_STATE_DEFAULT: the state the pinctrl handle shall be put
+ *     into as default, usually this means the pins are up and ready to
+ *     be used by the device driver. This state is commonly used by
+ *     hogs to configure muxing and pins at boot, and also as a state
+ *     to go into when returning from sleep and idle in
+ *     .pm_runtime_resume() or ordinary .resume() for example.
+ * @PINCTRL_STATE_IDLE: the state the pinctrl handle shall be put into
+ *     when the pins are idle. This is a state where the system is relaxed
+ *     but not fully sleeping - some power may be on but clocks gated for
+ *     example. Could typically be set from a pm_runtime_suspend() or
+ *     pm_runtime_idle() operation.
+ * @PINCTRL_STATE_SLEEP: the state the pinctrl handle shall be put into
+ *     when the pins are sleeping. This is a state where the system is in
+ *     its lowest sleep state. Could typically be set from an
+ *     ordinary .suspend() function.
