In the initial driver we cancelled deferred work, but there is still a
window of time where a new interrupt could result in new deferred work
executed after the link is disabled, leading to an IO error. While we
did not see this IO error on RT5682-based platforms, the code pattern
is similar to the RT700 case where the IO error was noted, so the fix
is added for consistency.
This patch uses an 'disable_irq_lock' mutex to prevent new interrupts
from happening after the start of the system suspend. The choice of a
mutex v. a spinlock is mainly due to the time required to clear
interrupts, which requires a command to be transmitted by the
SoundWire host IP and acknowledged with an interrupt. The
'interrupt_callback' routine is also not meant to be called from an
interrupt context.
An additional 'disable_irq' flag prevents race conditions where the
status changes before the interrupts are disabled, but the workqueue
handling status changes is scheduled after the completion of the
system suspend. On resume the interrupts are re-enabled already by the
io_init routine so we only clear the flag.
The Fixes tag points to a 5.10 commit, there's no need to propagate
this change to earlier upstream versions.

The resume operation relies on multiple transactions to synchronize
the regmap state, make sure the timeout is one order of magnitude
larger than an individual transaction, so that timeouts of failed
transactions are detected first.

The (new?) style of clk registration uses clk_hw based APIs so that we
can more easily see the difference between clk providers and clk
consumers. Use the clk_hw based APIs to do this and migrate to devm for
the clkdev creation so that we can reduce the amount of code.

With SND_SOC_AMD_RV_RT5682_MACH using the i2c version of the
driver, we can easily get a build failure when I2C is built-in
but soundwire is not:
WARNING: unmet direct dependencies detected for SND_SOC_RT5682
Depends on [m]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && (I2C [=y] || SOUNDWIRE [=m]) && (SOUNDWIRE [=m] || !SOUNDWIRE [=m]) && (I2C [=y] || !I2C [=y])
Selected by [y]:
- SND_SOC_AMD_RV_RT5682_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_ACP3x [=y] && I2C [=y] && CROS_EC [=y]

Rework the driver to have three separate modules, with the
main driver just dealing with the common bits and the actual
initialization as part of i2c and sdw specific modules.
The conversion is fairly mechanical to keep it easy to review,
i.e. it moves code around with the minimal required renaming
and changes.

There is a need to use RT5682 as DAI clock master for other codecs
within a platform, which means that the DAI clocks are required to
remain, regardless of whether the RT5682 is actually running
playback/capture.
The RT5682 CCF basic functions are implemented almost by the existing
internal functions and asoc apis. It needs a clk provider (rt5682 mclk)
to generate the bclk and wclk outputs.
The RT5682 CCF supports and restricts as below:
1. Fmt of DAI-AIF1 must be configured to master before using CCF.
2. Only accept a 48MHz clk as the clk provider.
3. Only provide a 48kHz wclk and a set of multiples of wclk as bclk.
There are some temporary limitations in this patch until a better
implementation.

The field "is_sdw" is used for distinguishing the driver whether is run
in soundwire mode or not. That will run the separated setting in runtime
to make sure the driver can be run with the same build between i2s mode
and soundwire mode.
