ASoC: Updates for v6.19
This is a very large set of updates, as well as some more extensive
cleanup work from Morimto-san we've also added a generic SCDA class
driver for SoundWire devices enabling us to support many chips with
no custom code. There's also a batch of new drivers added for both
SoCs and CODECs.
- Added a SoundWire SCDA generic class driver, pulling in a little
regmap work to support it.
- A *lot* of cleaup and API improvement work from Morimoto-san.
- Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm
drivers.
- Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
TAS5815, TAS5828 and TAS5830.
This also pulls in some gpiolib changes supporting shared GPIOs in the
core there so we can convert some of the ASoC drivers open coding
handling of that to the core functionality.

Currently, on ASUS projects, the TAS2781 codec attaches the speaker GPIO
to the first tasdevice_priv instance using devm. This causes
tas2781_read_acpi to fail on subsequent probes since the GPIO is already
managed by the first device. This causes a failure on Xbox Ally X,
because it has two amplifiers, and prevents us from quirking both the
Xbox Ally and Xbox Ally X in the realtek codec driver.
It is unnecessary to attach the GPIO to a device as it is static.
Therefore, instead of attaching it and then reading it when loading the
firmware, read its value directly in tas2781_read_acpi and store it in
the private data structure. Then, make reading the value non-fatal so
that ASUS projects that miss a speaker pin can still work, perhaps using
fallback firmware.

Create debugfs files that can be used to perform factory calibration.
During manufacture, the production line must perform a factory calibration
of the amps. This commit adds this functionality via debugfs files.
As this is only needed during manufacture, there is no need for this to be
available in a normal system so a Kconfig item has been added to enable
this. The new Kconfig option is inside a sub-menu because items do not
group and indent if the parent is invisible or there are multiple parent
dependencies. Anyway the sub-menu reduces the clutter.
cs35l56_hda_apply_calibration() has been changed to return an error code
that can be reported back through the debugfs write. The original call to
this function doesn't check the return code because in normal use it
doesn't matter whether this fails - the firmware will default to a safe
calibration for the platform. But tooling using the debugfs files might
want to know if there was an error.

A moderately large collection of driver specific fixes, plus a few new
quirks and device IDs. The NAU8821 changes are a little large but more
in mechanical ways than in ways that are complex.

case of tas5825
The software reset for TAS5825 is different form other chips, as it will
set as 0x11 instead of 0x1 during reset in the tasdevice_reset(). So set
tas2781_hda::tasdevice_priv::chip_id as TAS5825, tasdevice_reset() can
work correctly.

The __component_match_add function may assign the 'matchptr' pointer
the value ERR_PTR(-ENOMEM), which will subsequently be dereferenced.
The call stack leading to the error looks like this:
hda_component_manager_init
|-> component_match_add
|-> component_match_add_release
|-> __component_match_add ( ... ,**matchptr, ... )
|-> *matchptr = ERR_PTR(-ENOMEM); // assign
|-> component_master_add_with_match( ... match)
|-> component_match_realloc(match, match->num); // dereference
Add IS_ERR() check to prevent the crash.

Pull pin control updates from Linus Walleij:
"We have GPIO awareness in the pin control core and an interesting
AAEON driver.
Core changes:
- Allow pins to be identified/marked as GPIO mode with a special
callback.
The pin controller core is now "aware" if a pin is in GPIO mode if
the callback is implemented in the driver, and can thus be marked
as "strict", i.e. disallowing simultaneous use of a line as GPIO
and another function such as I2C.
This is enabled in the Qualcomm TLMM driver and also implemeted
from day 1 in the new Broadcom STB driver
- Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL
to better describe what the config is doing, as well as making it
more intuitive what shall be returned when reading this property
New drivers:
- Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver
- Qualcomm Glymur family pin controller driver
- Broadcom STB family pin controller driver
- Tegra186 pin controller driver
- AAEON UP pin controller support.
This is some special pin controller that works as an external
advanced line MUX and amplifier for signals from an Intel SoC. A
cooperative effort with the GPIO maintainer was needed to reach a
solution where we reuse code from the GPIO aggregator/forwarder
driver
- Renesas RZ/T2H and RZ/N2H pin controller support
- Axis ARTPEC-8 subdriver for the Samsung pin controller driver
Improvements:
- Output enable (OEN) support in the Renesas RZG2L driver
- Properly support bias pull up/down in the pinctrl-single driver
- Move over all GPIO portions using generic MMIO GPIO to the new
generic GPIO chip management which has a nice and separate API
- Proper DT bindings for some older Broadcom SoCs
- External GPIO (EGPIO) support in the Qualcomm SM8250
Deleted code:
- Dropped the now unused Samsung S3C24xx drivers"

This generic pin config property is confusingly named so let's
rename it to make things clearer.
There are already drivers in the tree that use PIN_CONFIG_OUTPUT
to *read* the value of an output driven pin, which is a big
semantic confusion for the head: are we then reading the
setting of the output or the actual value/level that is put
out on the pin?
We already have PIN_CONFIG_OUTPUT_ENABLE that turns on driver
buffers for output, so this can by logical conclusion only
drive the voltage level if it should be any different.
But if we read the pin, are we then reading the *setting* of
the output value or the *actual* value we can see on the
line?
If the pin has not first been set into output mode with
PIN_CONFIG_OUTPUT_ENABLE, but is instead in some input mode
or tristate, what will reading this property actually
return?
Reading the current users reading this property it is clear
that what we read is the logical level of the pin as 0 or 1
depending on if it is low or high.
Rename it to PIN_CONFIG_LEVEL so it is crystal clear that
we set or read the voltage level of the pin and nothing else.

Now move the all remaining codec drivers from sound/pci/hda to
sound/hda/codecs subdirectory. Some drivers are put under the further
vendor subdirectory, and the vendor helper code (*_helper.c) are put
under helpers subdirectory. Also the sub-codec drivers are moved under
a different subdirectory, sound/hda/codecs/sub-codecs, for
distinguishing from the main HD-audio codec drivers.
The prefix patch_ and hda_ as well as the suffix _helper are dropped
from file names as they are mostly superfluous.
No functional changes but just file path shuffling.
