This information is written into the non-volatile area
where keeps data whether factory reset or OS update.

This patch adds support for the 8 channel PDM-to-I2S/TDM converter. The
ADAU7118 converts four stereo pulse density modulation (PDM) bitstreams
into one pulse code modulation (PCM) output stream. The source for the PDM
data can be eight microphones or other PDM sources. The PCM audio data is
output on a serial audio interface port in either inter-IC serial (I2S) or
time domain multiplexed (TDM) format.

The snd_pcm_hw_constraint_minmax() works fine when a single codec is
connected to a single CPU DAI, but in multicodec or DPCM setup the
constraints placed by the driver will apply to the whole PCM stream (FE
included) and thus prevents more than 8 playback channels for example.

According the documentation for snd_soc_update_bits the API
will return a 1 if the update was successful with a value change,
a 0 if the update was successful with no value change or a negative
if the command just failed.
So the value of return in the driver needs to be checked for being less
then 0 or the caller may indicate failure when the value actually
changed.

referring to registers not existing on that device.
It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2
Volume" controls was failing during ALSA state restoring at boot time:
"amixer: Mixer hw:0 load error: Device or resource busy"
Reading some registers through I2C was failing with EBUSY error and
indeed these registers were not available according to the datasheet.
To fix this controls not available on WM1811 are moved to a separate
array and registered only for WM8994 and WM8958.
There are some further differences between WM8994 and WM1811,
e.g. registers 603h, 604h, 605h, which are not covered in this patch.

static const. Makes the object code smaller by 37 bytes.

This patch supports some type of machine drivers that set 0 to mclk
when sound device goes to idle state. After applied this patch,
sysclk == 0 means there is no constraint of sound rate and other
values will set constraints which is derived by sysclk setting.
Original code refuses sysclk == 0 setting. But some boards and SoC
(such as RockPro64 and RockChip I2S) has connected SoC MCLK out to
ES8316 MCLK in. In this case, SoC side I2S will choose suitable
frequency of MCLK such as fs * mclk-fs when user starts playing or
capturing.
Bad scenario as follows (mclk-fs = 256):
- Initialize sysclk by correct value (Ex. 12.288MHz)
- ES8316 set constraints of PCM rate by sysclk
48kHz (1/256), 32kHz (1/384), 30.720kHz (1/400),
24kHz (1/512), 16kHz (1/768), 12kHz (1/1024)
- Play 48kHz sound, it's acceptable
- Sysclk is not changed
- Play 32kHz sound, it's acceptable
- Set sysclk by 8.192MHz (= fs * mclk-fs = 32k * 256)
- ES8316 set constraints of PCM rate by sysclk
32kHz (1/256), 21.33kHz (1/384), 20.48kHz (1/400),
16kHz (1/512), 10.66kHz (1/768), 8kHz (1/1024)
- Play 48kHz again, but it's NOT acceptable because constraints
list does not allow 48kHz

This patch removes redundant null checks for optional MCLK clock.
And fix DT binding document for changing clock property to optional
from required.

This patch introduce clock property for MCLK master freq control.
Driver will set rate of MCLK master if set_sysclk is called and
changing sysclk by board driver.

There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

Now, the ChromeOS EC core driver has nothing related to an MFD device, so
move that driver from the MFD subsystem to the platform/chrome subsystem.
