Audio is distorted during first 3 secs on headset record
while doing device switch from dmic to headset mic.
Disable BCS before slow insertion detection and enable it
afterwards to resolve the issue.

Enabling watchdog interrupt during bind causes spurious
interrupts. Disable interrupts during bind and enable
during path setup to fix this. Also enable and
disable interrupt for ear pa for wcd938x.

OCP is resulting in mute issues during audio playback.

Invalid memory access happens in wcd937x_suspend if
component bind for slave fails. This is because
as part of component_unbind devres_release_group is called
which removes every node from list and frees corresponding memory.
This results in invalid memory access for wcd937x in wcd937x_suspend.
Do kfree and set drvdata to NULL if component_bind fails
to resolve the issue.

Get Logical Address failure comes after SSR during rigorous testing.
This calls removal of swr master device attached. Once removal occurs
further headset insertion/removal does not get detected. Do not remove
swr master device attached to fix the issue.

If we start playback on special hs after record is done and perform
SSR/PDR then playback gets paused. This happens because ANA_TX_DIV2_CLK
which needs to be enabled for special hs gets disabled after record
is stopped. Maintain a count for ANA_DIV2_CLK to enable/disable it
as required.

the buck, is not cleared during powerup if it is already enabled.
This causes suspend to disable buck even during active usecase.
