If surge protection is enabled, it interferes with HPHL
and does not give proper impedance for high impedance cable.
Disable surge protection before impedance detection and
enable it again after impedance detection on wcd937x and wcd938x.

OCP is resulting in mute issues during audio playback.
Talos has surge protection enabled in hw. Thus
OCP can be disabled for talos.

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.

This calls removal of swr master device attached. Once removal occurs
further headset insertion/removal does not get detected. Do not remove

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.
