47ceabd99a ALSA: hda: cs35l41: Support Firmware switching and reloading 
This is required to support CS35L41 calibration.

By default, speaker protection firmware will be loaded, if
available. However, different firmware is required to run
the calibration sequence, so it is necessary to add support
to be able to unload, switch and reload firmware.

This patch adds 2 ALSA Controls for each amp:
"DSP1 Firmware Load"
"DSP1 Firmware Type"

"DSP1 Firmware Load" can be used to unload and
load the firmware.
"DSP1 Firmware Type"  can be used to switch the
target firmware to be loaded by "DSP1 Firmware Load"

Since loading firmware can add new ALSA controls, it is
necessary to ensure the firmware loading is run asynchronously
from the ALSA control itself to prevent deadlocks.

Note: When switching between firmwares, an ALSA control is
only added if it has not previously existed. If it had existed
previously, it will be re-enabled instead.

1873ebd30c ALSA: hda: cs35l41: Support Hibernation during Suspend 
CS35L41 supports hibernation during suspend when using
DSP firmware.
When the driver suspends it will hibernate the part, if
firmware is running, and resume will wake from hibernation.
CS35L41 driver will suspend/resume when requested by
hda driver.
Note that suspend/resume and hibernation is only supported
when firmware is running.

The Subsystem ID is read from the HDA driver, and will
be used by the CS35L41 driver to be able to uniquely
identify the laptop, which is required to be able to
define firmware to be used by specific models.

2e81e1fffd ALSA: hda: cs35l41: Add initial DSP support and firmware loading 
This patch adds support for the CS35L41 DSP.
The DSP allows for extra features, such as running
speaker protection algorithms and hibernations.

To utilize these features, the driver must load
firmware into the DSP, as well as various tuning
files which allow for customization for specific
models.

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
regmap_update_bits with usleep_range to wait for the same 3000us that
reg_sequence had.

85c25662d1 ALSA: hda: cs35l41: Make cs35l41_hda_remove() return void 
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.
