+/**
+ * @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.
+ * @PINCTRL_STATE_IDLE: the state the pinctrl handle shall be put into
+ * when the pins are idle. Could typically be set from a
+ * pm_runtime_suspend() operation.
+ * @PINCTRL_STATE_SLEEP: the state the pinctrl handle shall be put into
+ * when the pins are sleeping. Could typically be set from a
+ * common suspend() function.
