Export the Q7.8 volume control helpers to allow reuse
by other ASoC drivers. These functions handle 16-bit
signed Q7.8 fixed-point format values for volume controls.
Changes include:
- Rename q78_get_volsw to sdca_asoc_q78_get_volsw
- Rename q78_put_volsw to sdca_asoc_q78_put_volsw
- Add a convenience macro SDCA_SINGLE_Q78_TLV and
SDCA_DOUBLE_Q78_TLV for creating mixer controls
This allows other ASoC drivers to easily implement controls
using the Q7.8 fixed-point format without duplicating code.

According to the Intel sof design, it will create the name prefix
appended with amp index for the amp codec only, such as:
rt1318-1, rt1318-2, etc...
But the rt1320 is a codec with amp and mic codec functions, it doesn't
have the amp index in its name prefix as above.
And then it will be hard to identify the codec if in multi-rt1320 case.
So we add a flag to force the amp index to be appended.

Normally the SDCA jack detection controls will be named after the GE

controlled by the jack selection. However, in the case that the jack
selection only controls a single widget the control will be named after
the SU widget that implements that. It is rather confusing to have the
jack detection controls change naming scheme between devices. Add a new
widget type, similar to mixer widgets, to force use of the control name
rather than falling back to the widget names.
There is already a version of the mixer widget that forces use of the

James Calligeros <jcalligeros99@gmail.com> says:
This series introduces some infrastructure to allow platform drivers
to specify what a DAI should be doing when it is not active on the
bus. The primary use case for this is configuring bus keepers which
may be integrated into various codecs. The instigating use case for
this functionality is an interesting bus topology on Apple Silicon
laptops with multiple codecs.
Most Apple Silicon laptops have six codecs split into groups of
three, driving a pair of dual opposed woofers and a tweeter for
L/R stereo sound. These codecs report the voltage and current across
their connected voice coils back to the SoC via the SDOUT pin,
represented as PCM data sent via configurable TDM slots. This data is
used in conjunction with the connected speaker's Thiele/Small Parameters
to ensure that the speaker is not being driven to levels that would
permanently damage them. This is integrated into CoreAudio on macOS.
speakersafetyd[1] handles this for Linux.
All of the codec SDOUT pins are attached to a single receiver port
on the SoC's I2S peripheral, however are split across two physical
data lines (one each for the left and right codec groups). The receiver
has an OR gate in front of it, which is used to sum the two lines.
If at any point a codec is trying to transmit data, and the "opposite"
line ends up floating high, the transmitting codec's data will be
corrupted. We need to guarantee that the idle line stays idle.
In the downstream Asahi Linux kernel[2], we set up one codec in each
group to zero-fill or pull down its line while a codec on the opposite
line is actively transmitting. This is done entirely in the codec
driver, however this approach is over-fit for this one use case. This
sort of functionality may also be of use for other hardware, so following
previous mailing list discussions[3], I have tried to expose the
functionality in a more configurable and generic way.
I have integrated this approach into our downstream platform driver
and select Devicetrees as an example of how this mechanism is intended
to be used[4].

Some audio devices, like certain Texas Instruments codecs, integrate
configurable bus keepers that dictate the codec's behaviour during
idle TDM slots. Now that we have definitions for various idle modes,
add a snd_soc_dai_set_tdm_idle() operation to control this in a
standardised way.
This is useful on Apple Silicon laptops, where a single I2S bus is
comprised of two physical lines which are ORed just before the
receiving port. When a codec on one line is transmitting, we must
guarantee that the other line is low. We can achieve this by
configuring one codec on each line to use its bus keeper to fill
its line with zeroes during the active slots of the other line.

Some audio devices, such as certain Texas Instruments codecs,
include configurable bus keepers. We currently don't have
a standardised way to configure such hardware, and instead
rely on the hardware initialising setting itself up into a
sane state. There are situations where this is insufficient,
however, and some platforms require more concrete guarantees
as to the state of the bus, and being able to explicitly
configure bus keepers enables this.
For example, some Apple Silicon machines have an odd bus topology where
the SDOUT pins of all codecs are split across two data lines, which
are summed via an OR gate in front of the receiving port on the
SoC's I2S peripheral. Each line must transmit 0 while a codec
on the other line is actively transmitting data, or the SoC
will receive garbage data. To do this, one codec on each line
must be configured to transmit zeroes during the other line's
active TDM slots.
Thus, we define seven possible bus-keeping modes that a device can
be in: NONE (UB/as initialised), OFF (explicitly disabled), ZERO
(actively transmit a 0), PULLDOWN, HIZ (floating), PULLUP, and
DRIVE_HIGH.
These will be consumed by CODEC/CPU drivers via a common DAI
op, enabling the explicit configuration of bus keepers where
required.

Move the ASP register patches to a separate struct and apply this from the
ASP DAI probe() function so that the registers are only patched if the DAI
is part of a DAI link.
Some systems use the ASP as a special-purpose interconnect and on these
systems the ASP registers are configured by a third party (the firmware,
the BIOS, or another device using the amp's secondary host control
interface).
If the machine driver does not hook up the ASP DAI then the ASP registers
must be omitted from the patch to prevent overwriting the third party
configuration.
If the machine driver includes the ASP DAI in a DAI link, this implies that
the machine driver and higher components (such as alsa-ucm) are taking
ownership of the ASP. In this case the ASP registers are patched to known
defaults and the machine driver should configure the ASP.

When simple-audio-card programs sysclk for CPU and codec DAIs during
hw_params, the ordering of these calls may matter on some platforms.
Some CPU DAIs finalize or adjust the MCLK rate as part of their
set_sysclk() callback (for example by calling clk_set_rate()). If the
codec sysclk is configured before the CPU DAI applies the final MCLK
rate, the codec may configure its internal clocking based on a
non-final MCLK value.
Such situations can arise depending on the clock provider/consumer
relationship between the CPU DAI and the codec.
Introduce an explicit sysclk ordering enum in simple-card-utils and use
it to control the order of snd_soc_dai_set_sysclk() calls in the mclk-fs
handling path. The default behaviour remains unchanged (codec-first)
to avoid regressions.

Now, all DAPM users are using function to handling it.
We can capsuling it. This patchset moves struct snd_soc_dapm_context into
soc-dapm.c, and remove un-used functions.

The main goal is to convert drivers to use GPIO descriptors. While reading
the code, I think it is time to remove ak4641 and pxa2xx-ac97 driver,
more info could be found in commit log of each patch.
Then only need to convert sound/arm/pxa2xx-ac97-lib.c to use GPIO
descriptors. Not have hardware to test the pxa2xx ac97.
Since commit d6df7df7ae ("ARM: pxa: remove unused board files"), there
has been no in-tree user of the AK4641 codec driver. The last user
(HP iPAQ hx4700) was a non-DT PXA board file that instantiated the device
via I2C board data; that code was removed as part of the PXA board-file
purge.
The AK4641 driver was introduced ~2011 and still probes only via the I2C
device-ID table ('.id_table'), without an 'of_match_table', so there are
no upstream Devicetree users to retain. With no in-tree users left, remove
the driver.

Because struct snd_soc_dapm_context is soc-dapm framework specific, user
driver don't need to access its member directly, we would like to hide
them. struct snd_soc_dapm_context will be removed from header in the
future.
Current card/component are using dapm_context instance. But it will be
moved to soc-dapm.c, and we can use will be only pointer. Makes it to
pointer.

Add a function cs_amp_devm_get_vendor_specific_variant_id() to return
a vendor-specific hardware identifier string (if there is one) and use
it to fetch an identifier from Dell SSIDExV2 UEFI variable content.
Dell use the same PCI SSID on multiple products that might have different
audio hardware and thus need different firmware for the amplifier DSP.
The SSIDExV2 string contains additional system identifiers, and the
second field is a 2-character audio hardware identifier.
There are older Dell models with Cirrus Logic amplifiers that have the
SSIDExV2 UEFI variable but do not have the 2-character audio ID in the
second field. The SSIDExV2 is ignored if the second field is not
2 characters.
