Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

/**
|
|
* @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.
