If Hibern8 enter/exit fails and we also see some UIC errors at the same
time, we would see following 2 recovery paths running in parallel to
restore the host and device communication.
Context-1: ufshcd_uic_hibern8_exit() -> ufshcd_link_recovery() ->
ufshcd_reset_and_restore()
Context-2: ufshcd_err_handler()->ufshcd_reset_and_restore()
This change fixes this race by making the ufshcd_link_recovery() to wait
for the already scheduled ufshcd_err_handler() to finish running and then
schedule the error handler again to make sure that host-device link is
reestablished.
While we are fixing the above race, similar race could happen between
ufshcd_eh_host_reset_handler() and ufshcd_err_handler() hence fix the
error handling in ufshcd_eh_host_reset_handler() same way as fixed in
ufshcd_link_recovery().

When device switch to suspend state the gpio and pinctrl need to be
configured properly to prevent the touch controller current leakage in
device suspend state. The pinctrl must be configure first before
the gpio configuration. Select the pinctrl sleep state and after that
in gpio configuration part free both IRQ and reset gpio, and also set
direction of reset gpio to be input. If the gpio and pinctrl is not in
proper state the touch controller will not switch to the deep sleep state
and it will start consume current during the device suspend state.
To prevent this leakage current issue, pinctrl and gpio must be
configured properly.

devm_pinctrl_get() does not release the ownership of mux function
of pins in the associated pin-group whenever a failure occurs in
driver probe routine. i.e struct pin_desc's mux_owner field is
still marked as being in use after a failure occurs in probe.
As a result of this, if another driver tries to acquire the
ownership of same pin, it gets an error while applying that
setting. To fix this, explicitly release the mux function
ownership of the the pin, by adding a new pin-group in pinctrl
DT and a new pinctrl state in touch device's DT node. This new
pin-group does not have a function setting (qcom,pin-func property).
This new state is explicitly activated during a probe failure
and driver remove routine to release the mux function ownership.
The patch also reorganizes the pinctrl related code in driver.

Earlier, QSEECom driver had several problems such as exposing many

tunnel to communicate between secure and non secure world. SMCInvoke
driver aims to achieve that.
