| * @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_INIT: normally the pinctrl will be set to "default" | |
| * before the driver's probe() function is called. There are some | |
| * drivers where that is not appropriate becausing doing so would | |
| * glitch the pins. In those cases you can add an "init" pinctrl | |
| * which is the state of the pins before drive probe. After probe | |
| * if the pins are still in "init" state they'll be moved to | |
| * "default". | |
| * @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. | |
