The Amp Name will be a channel identifier (L or R), and an

CLSA0100 Laptop does not contain configuration inside ACPI,
instead the hardware configuration needs to be hardcoded.
Hardcode GPIO2 Interrupt in the driver for CSLA0100.

The CS35L41 can produce interrupts on error.
When the interrupts occur, the driver will report
the error, but errors will only be fixed after playback
finishes.

This API was required for CLSA0100 laptop, which did not
have correct properties inside ACPI. The required values
are now hardcoded inside the driver so this is no longer
needed.
Without this api, there CLSA0100 can now use the generic
cs35l41 fixup, like the other laptops.
All other laptops will read the Speaker Position from
ACPI and set the channel map from within the driver.

External boost enables sequences for devices with or without GPIO1 as
VSPK switch are the same if devices are put in safe mode from reset.
As a previous patch put all external boost devices into safe mode
from reset, all external boost devices can be handled in the same way
for stream open and close.
The only difference is that devices without an VSPK switch can not be
put in reset and devices with it can be put into reset if a
configuration is applied.
The function cs35l41_hda_safe_reset is created to handle the safe reset
of the chip, and as systems without VSPK switch are not supported
anymore, only the CS35L41 HDA driver should check its return.

For each case, only log the last regmap access, so it doesn't get
overwritten, and as all regmap access should show the same issues
logging the last one should be enough.
Change to dev_err to log this error.
Also, differentiate between a regmap access failure and invalid
playback action.

Remove cs35l41_hd_reg_sequence as it adds a layer of flexibility not needed.
As cs35l41_hda_(start/stop)_bst is a single register, it can be replaced by

Having CS35L41_PWR_CTRL2 on cs35l41_hda_config overwrites the boost
configuration for internal boost.
So move it to the initialization part and use regmap_update_bits to
only change the correct bits.

Up to now cs35l41_hda_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.

regmap_register_patch can't be used to apply the probe sequence as a
patch is already registers with the regmap by
cs35l41_register_errata_patch and only a single patch can be attached to
a single regmap. The driver doesn't currently rely on a cache sync to
re-apply this probe sequence so simply switch it to a multi write.
