Subject: [PATCH AUTOSEL 6.0 19/39] ASoC: rt711-sdca: fix the latency time of clock stop prepare state machine transitions

From: Shuming Fan <shumingf@...ltek.com>

[ Upstream commit c7d7d4e7bb1290cc473610b0bb96d9fa606d00e7 ]

Due to the hardware behavior, it takes some time for CBJ detection/impedance sensing/de-bounce.
The ClockStop_NotFinished flag will be raised until these functions are completed.
In ClockStopMode0 mode case, the SdW controller might check this flag from D3 to D0 when the
jack detection interrupt happened.
