Native audio playback is muted after adsp subsystem restart,
because codec device_reset() API is called even before device_down()
API finishes execution. This causes audio to mute, as codec is not
in proper reset state. Add new lock to synchronize codec subsystem
restart APIs.

TASHA_IS_1_1 macro checks only for version number.
This macro returns true for tavil codec. So modify
tasha macros to check for codec and version.

As there are many hardware version of wcd934x codec. Add version
check in the code so that userspace can get the version info.

WCD9XXX irq driver uses device tree APIs in the
IRQ handler. Device tree APIs disable interrupts
for the duration of their execution. Do not use
these APIs in the wcd9xxx irq handler to reduce
the interrupt off (irqsoff) latency.

Depending on the impedance across HPHL and HPHR, set classh
configurations so as to avoid false OCP events.
Move wcd9xxx_registers.h to uapi folder, as this header
file is used by userspace for wdc9330 codec.

DMIC clock on ECPP(Echo Cancellation Ping-Pong) path can be set to
lower clock rate to avoid power consumption. Change configures the
DMIC clock rate on ECPP path based on device tree settings.

Codec reset gpio configuration needs to be updated
before slimbus master component is initialized otherwise
codec cannot be enumerated on the bus. Add a new platform
device driver to update the codec reset gpio configuration
to valid state (output, drive-strength) before slimbus
is initialized.

as the bus is not available. Avoid codec read/write, until the
