Registers to set Mute, Volume and Posture are inside firmware,
which means they should be added to the list of registers set inside
firmware, in case they vary across Device or Revision.
These three registers are also used for controls, so additional
handling is required to be able to obtain and set the register inside
ALSA controls.

'devid' is an enum, thus cast of pointer on 64-bit compile test with
clang and W=1 causes:
tas2764.c:879:19: error: cast to smaller integer type 'enum tas2764_devid' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
One of the discussions in 2023 on LKML suggested warning is not suitable
for kernel. Nothing changed in this regard for more than a year, so
assume the warning will stay and we want to have warnings-free builds.

Add a codec driver for the Cirrus Logic CS48L32 audio DSP.
The CS48L32 is a low-power audio DSP with microphone inputs for
"Always on Voice" (i.e. voice trigger) and voice command processing.
It has a programmable Halo Core DSP and a variety of power-efficient
fixed-function audio processors, with configurable digital mixing
and routing.
There are two I2S/TDM audio serial ports.
Four analogue inputs are available through IN1. These feed into a
2-channel ADC through an analogue mux. There is an ALSA control for
each IN1 ADC channel to select which analogue input to use.
A dedicated digital mic (DMIC) PDM input is available on IN2.
Two PDM outputs can feed DMIC inputs on another codec or a host DMIC/PDM
input.
An on-board regulator provides a power supply or bias voltage to
attached microphones. Three switchable MICBIAS outputs are fed from this
allowing only the microphone in use to be powered-up. There are DAPM
widgets for these outputs: MICBIAS1A, MICBIAS1B and MICBIAS1C. The machine
driver must create a DAPM route from the required MICBIAS1x widget to the
INn input widgets to make the MICBIAS switch on when the audio input is
powered-up. For example if the microphone feeding CS48L32 pin IN1LN_1 is
powered from MICBIAS1A, the machine driver must create the path:
(sink) IN1LN_1 <----- (source) MICBIAS1A

This series introduces a number of changes to the drivers for
the Texas Instruments TAS2764 and TAS2770 amplifiers in order to
introduce (and improve in the case of TAS2770) support for the
variants of these amps found in Apple Silicon Macs.
Apple's variant of TAS2764 is known as SN012776, and as always with
Apple is a subtly incompatible variant with a number of quirks. It
is not publicly available. The TAS2770 variant is known as TAS5770L,
and does not require incompatible handling.
Much as with the Cirrus codec patches, I do not
expect that we will get any official acknowledgement that these parts
exist from TI, however I would be delighted to be proven wrong.
This series has been living in the downstream Asahi kernel tree[1]
for over two years, and has been tested by many thousands of users
by this point[2].
v4 drops the TDM idle TX slot behaviour patches. I experimented with
the API discussed in v3, however this did not work on any of the machines
I tested it with. More tweaking is probably needed.

TAS2764 contains an ADC that reports the chip's die temperature.
The temperature in degrees Celsius is yielded by subtracting 93
from the raw value reported by the ADC.
Expose the codec die temperature to the hwmon interface.
The chip will initialise the temperature register to 2.6 *C
to avoid triggering over temp protection. As the ADC is powered
down during software shutdown, this value will persist until the
chip is fully powered up (e.g. when the PCM it's attached to is
opened). When the chip is powered back down, the last value sampled
will persist in the register.

TAS2770 includes an ADC which reports the chip's die temperature.
As per the datasheet, the temperature in degrees Celsius is derived
by taking the raw value stored in the ADC's registers, dividing by 16,
then subtracting 93.
Create and register a hwmon device to expose the chip's die temperature
to the hwmon interface.
The ADC is shut down during software shutdown mode, and its registers
are initialised to 0 on reset. This means that the die temperature will
read -93 *C until the chip has been fully powered up at least once (e.g.
the PCM its attached to is opened). Once the chip is put into software
shutdown again, the ADC will also shut down. The last value sampled
before this happens will persist in the ADC's registers.

Apple's SN012776 driver has some peculiar aspects to its behavior that
are suspected to work around issues in the codec part. Add a module
parameter for enabling individual quirks that should be imitated after
the Apple driver.
Setting some of these by default seems to be required. For example,
setting 0xf fixes an issue with transient overcurrent errors which
can crash the chip until the next system reboot. To be safe, let's
enable all of them by default.

TAS2764 has a number of undocumented registers between
page 0xf0 and 0xff. These are used to apply in-silicon
quirks and workarounds at runtime.
Raise the regmap max register to 0xffff to cover any
quirks registers.

IRQ handling was added in commit dae191fb957f ("ASoC: tas2764: Add IRQ
handling") however that same commit masks all interrupts coming from
the chip. Unmask the "main" interrupts so that we can see and
deal with a number of errors including clock, voltage, and current.

When the part is reset in component_probe, do not forget to reinit the
regcache, otherwise the cache can get out of sync with the part's
actual state. This fix is similar to commit 0a0342ede303
("ASoC: tas2770: Reinit regcache on reset") which concerned the
tas2770 driver.
Fixes: 827ed8a0fa50 ("ASoC: tas2764: Add the driver for the TAS2764")

We don't actually support configuring the PDM input right now. Rather,
this is useful as a hack.
On Apple Silicon machines, amps are split between two I2S buses which
are logically ANDed internally at the SoC. Odd and even slot groups are
driven by amps on either bus respectively. Since the signals are ANDed,
unused slot groups must be driven as zero to avoid corrupting the data
from the other side.
On most recent machines (TAS2764-based), this is accomplished using the
"SDOUT zero mask" feature of that chip. Unfortunately, TAS2770 does not
support this. It does support zeroing out *all* unused slots, which
works well for machines with a single amp per I2S bus. That is all,
except one.
The 13" M1 MacBook Pro is the only machine using TAS2770 and two amps
per I2S bus:
L Bus: SPK0I SPK0V Hi-Z Hi-Z SPK2I SPK2V Hi-Z Hi-Z
R Bus: Hi-Z Hi-Z SPK1I SPK2V Hi-Z Hi-Z SPK3I SPK3V
To ensure uncorrupted data, we need to force all the Hi-Z periods to
zero. We cannot use the "force all zero" feature, as that would cause a
bus conflict between both amps. We can use the pull-down feature, but
that leaves a few bits of garbage on the trailing edge of the speaker
data, since the pull-down is weak.
This is where the PDM transmit feature comes in. With PDM grounded and
disabled (the default state), the PDM slot is transmitted as all zeroes.
We can use that to force a zero 16-bit slot after the voltage data for
each speaker, cleaning it up. Then the pull-down ensures the line stays
low for the subsequent slot:
L Bus: SPK0I SPK0V PDM0 PulDn SPK2I SPK2V PDM0 PulDn
R Bus: PDM0 PulDn SPK1I SPK2V PDM0 PulDn SPK3I SPK3V
Yes, this is a horrible hack, but it beats adding dummy slots that would
be visible to the userspace capture side. There may be some other way to
fix the logical AND behavior on the MCA side... that would make this
unnecessary.
("How does Apple deal with this"? - they don't, macOS does not use
IVSENSE on TAS2770 machines even though it's physically wired up,
but we want to do so on Linux.)

The ISENSE/VSENSE blocks are only powered up when the amplifier
transitions from shutdown to active. This means that if those controls
are flipped on while the amplifier is already playing back audio, they
will have no effect.
Fix this by forcing a power cycle around transitions in those controls.
