ASoC: Constify channel mapping array arguments in set_channel_map()
There is no need for implementations of DAI set_channel_map() to modify
contents of passed arrays with actual channel mapping.  Additionally,
the caller keeps full ownership of the array.

Constify these pointer arguments so the code will be safer and easier to
read (documenting the caller's ownership).

ef752c60e4 ALSA: hda: cs35l41: Set the max PCM Gain using tuning setting
Some systems requires different max PCM Gains settings than the default.
The current default value, when running firmware is 17.5 dB, which is
used for all systems. Some systems require lower values.
Value when running without firmware is 4.5 dB and remains unchanged.

Since the gain value is dependent on Tuning and Firmware, it can
change, so it cannot be saved in _DSD. Instead we can store it inside
a configuration binary file alongside the Firmware and Tuning files.

The gain value increments in steps of 1 dB, with value 0 representing
0.5 dB. The max value is 20, which corresponds to 20.5 dB.

76c121821a ASoC: cs35l41: Detect CSPL errors when sending CSPL commands
The existing code checks for the correct state transition after sending
a command. However, it is possible for the message box to return -1,
which indicates an error, if an error has occurred in the firmware.
We can detect if the error has occurred, and return a different error.
In addition, there is no recovering from a CSPL error, so the retry
mechanism is not needed in this case, and we can return immediately.

2ee06ff5d7 ALSA: hda: cs35l41: Force a software reset after hardware reset
To ensure the chip has correctly reset during probe and system suspend,
we need to force a software reset, in case of systems where the
hardware reset is not available.

The software reset register was labelled as volatile but not readable,
however, it is readable, (just returns 0x0). Adding it to readable
registers means it will be correctly treated as volatile, and thus
will not be cached.

ASoC: cs35l41: Fix broken shared boost activation
Enabling the active/passive shared boosts requires setting SYNC_EN, but
*not* before receiving the PLL Lock signal.

Due to improper error handling, it was not obvious that waiting for the
completion operation times out and, consequently, the shared boost is
never activated.

Further investigations revealed the signal is triggered while
snd_pcm_start() is executed, right after receiving the
SNDRV_PCM_TRIGGER_START command, which happens long after the
SND_SOC_DAPM_PRE_PMU event handler is invoked as part of
snd_pcm_prepare().  That is where cs35l41_global_enable() is called
from.

Increasing the wait duration doesn't help, as it only causes an
unnecessary delay in the invocation of snd_pcm_start().  Moving the wait
and the subsequent regmap operations to the SNDRV_PCM_TRIGGER_START
callback is not a solution either, since they would be executed in an
IRQ-off atomic context.

Solve the issue by setting the SYNC_EN bit in PWR_CTRL3 register right
after receiving the PLL Lock interrupt.

Additionally, drop the unnecessary writes to PWR_CTRL1 register, part of
the original mdsync_up_seq, which would have toggled GLOBAL_EN with
unwanted consequences on PLL locking behavior.

fa3efcc36a ALSA: cs35l41: Use mbox command to enable speaker output for external boost
To enable the speaker output in external boost mode, 2 registers must
be set, one after another. The longer the time between the writes of
the two registers, the more likely, and more loudly a pop may occur.
To minimize this, an mbox command can be used to allow the firmware
to perform this action, minimizing any delay between write, thus
minimizing any pop or click as a result. The old method will remain
when running without firmware.

    like CODEC to CODEC links.
  - Clean up of the way we flag which DAI naming scheme we use to reflect
    the progress that's been made modernising things.
  - Merge of more of the Intel AVS driver stack, including some board
    integrations.
  - New version 4 mechanism for communication with SOF DSPs.

    platforms.

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.

ASoC: cs35l41: Add common cs35l41 enter hibernate function
Since the CS35L41 HDA driver also support hibernation, it
makes sense to move code from the ASoC driver to enter
hibernation into common code.

Since HDA must support laptops which do not support hibernation
due to lack of external boost GPIO it is necessary to
ensure the function returns an error when an unsupported
boost type is in use.

ASoC: cs35l41: Add support for hibernate memory retention mode
The cs35l41 supports a low power DSP memory retention mode. Add support
for entering this mode when then device is not in use.

ASoC: cs35l41: Update handling of test key registers
In preparation for the addition of PM runtime support move the test
key out of the register patches themselves. This is necessary to
allow the test key to be held during cache synchronisation, which is
required by the OTP settings which were unpacked from the device and
written by the driver.

Also whilst at it, the driver uses a mixture of accessing the test key
register by name and by address, consistently use the name.

ASoC: cs35l41: Create shared function for errata patches
ASoC and HDA systems require the same errata patches, so
move it to the shared code using a function the correctly
applies the patches by revision

Also, move CS35L41_DSP1_CCM_CORE_CTRL write to errata
patch function as is required to be written at boot,
but not in regmap_register_patch sequence as will affect
waking up from hibernation

ASoC: cs35l41: Convert tables to shared source code
To support CS35L41 in HDA systems the HDA driver
for CS35L41 would have to duplicate some functions
that already exist on ASoC driver
So instead of duplicate the code, use the new lib
source as a shared resource for both ASoC and HDA

Also, change the way CONFIG_SND_SOC_CS35L41 is
selected, as reported by Intel Kernel test robot,
it is possible to build SND_SOC_CS35L41_SPI/I2C
without the main driver, which would lead to build
failures.
