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