Because of a HW limitation in DSP, while switching
RCG from TX MCLK to VA MCLK for SVA use cases
a glitch is seen on AHB bus leading to data
corruption in registers.
So, while doing a mux switch for VA RCG clock selection,
do not configure the muxsel register in HLOS as it is
taken care in DSP itself as a workaround for HW limitation.

Vote for codec core and NPL clocks before regcache_sync
to avoid unclocked access of bolero registers.
Unvote once the regcache sync is done.

Reset GFMUX reg for va-macro and wsa-macro when adsp is up
after SSR. And check if clock is enabled before accessing
register to avoid kernel panic.

After SSR/PDR, the lpass clocks will be in off state. Force restart
clocks after SSR/PDR, if enabled before SSR/PDR, to reenable the clocks.

Exposure of driver bind/unbind to userspace via sysfs may
lead to unexpected behavior.
Hide bind and unbind by driver attribute.

When SSR happens, use dev_up flag in codec
to bail out from clock enablement routine.
During interrupt processing if clock enable fails during
SSR, exit isr routine without disabling clock.

bolero clocks for all the concurrency usecases like record
+ voice activation.
