Updates to clean-up the GPIOLIB dependency and a quirk for HP
SoundWire devices.

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:

This adds support for I2S/TDM links where the slot width varies
depending on the sample width, in a way that cannot be guessed by
component hw_params().

A typical example is:

- 16-bit samples use 16-bit slots
- 24-bit samples use 32-bit slots

There is no way for a component hw_params() to deduce from the information
it is passed that 24-bit samples will be in 32-bit slots.

Some audio hardware cannot support a fixed slot width or a slot width
equal to the sample width in all cases. This is usually due either to
limitations of the audio serial port or system clocking restrictions.

Merge series from Stephan Gerhold <stephan@gerhold.net>:

This series adds a simple driver and DT schema for the Awinic AW8738
audio amplifier. It's fairly simple - the main difference to
simple-amplifier is that there is a "one-wire pulse control" that
allows configuring the amplifier to one of a few pre-defined modes.
This can be used to configure the speaker-guard function (primarily
the power limit for the amplifier).

The "adata->i2s_irq" variable is unsigned so the error handling
will not work.

DETECT_MODE and PLL_START must be zero while HP_PDN and ADC_PDN are
both 1. If this condition is broken it can discharge FILT+ and it
can then take up to 1 second for FILT+ to recharge.

There is no workaround required for this, simply avoiding settings
and sequences that would break the requirement. The driver already
meets the requirement.

But it is not obvious from reading the code that this requirement
exists, or what is ensuring it is met. So it would not currently be
obvious to someone changing the code that there is certain special
behaviour that must be maintained.

To avoid accidental breakage in the future:

- Add comments into the register definitions to warn about this so
  that anyone changing the code around DETECT_MODE and PLL_START is
  aware of this requirement.

- Add a comment where PLL_START is written to 1 to highlight the
  requirement and why it is satisfied.

- Add a comment in cs42l42_setup_hs_type_detect() when DETECT_MODE is
  initialized.

The parts supported by this driver can have product-specific
firmware and tunings files. Typically these have been used on
embedded systems where the manufacturer is responsible for
installing the correct product-specific firmware files into
/lib/firmware. However, the linux-firmware repository places all
available firmwares into /lib/firmware and it is up to the driver to
select the correct product-specific firmware from that directory.

For example a product containing four smart amplifiers may provide
firmware specific for that product and each of the amplifiers may
have coefficient files containing tunings for their placement in the
mechanical design.

This change extends firmware (wmfw) and coefficient (bin) filenames
to be of the general form:

<cirrus/>part-dspN-fwtype<-system_name<-asoc_component_prefix>>.type

Where the cirrus subdirectory, system_name and asoc_component_prefix
are optional.

New files will be placed in the cirrus subdirectory to avoid
polluting the main /lib/firmware/ location. The generic name must be
searched in /lib/firmware before /lib/firmware/cirrus so that a
generic file in the new location does not override existing
product-specific files in the legacy location.

The search order for firmware files is:
  - cirrus/part-dspN-fwtype-system_name-asoc_component_prefix.wmfw
  - cirrus/part-dspN-fwtype-system_name.wmfw
  - part-dspN-fwtype.wmfw
  - cirrus/part-dspN-fwtype.wmfw

- Qualifications are added to the filename so that rightwards is more
  specific.
- The system_name is provided by the codec driver.
- The asoc_component_prefix is used to identify tunings for individual
  parts because it would already exist to disambiguate the controls
  and it makes it obvious which firmware file applies to which device.

The optional coefficient file must have the same filename
construction as the discovered wmfw except:
  - where the wmfw has only system_name then the bin file can
    optionally include the asoc_component_prefix. This is to allow a
    common wmfw for all amps but separate tunings per amp.

Some audio hardware cannot support the same slot width for all sample
widths, or a slot width equal to the sample width for all sample widths.
This is usually due either to limitations of the audio serial port or
system clocking restrictions.
A typical example would be:

- 16-bit samples in 16-bit slots
- 24-bit samples in 32-bit slots

The new dai-tdm-slot-width-map property allows setting a mapping of
sample widths and the corresponding tdm slot widths and slot counts.
Although the slot count is usually the same for all cases this does
allow for adding padding slots to maintain the same bitclk frequency.

The property is added to each endpoint node that needs the component
DAI to be told the TDM slot width and count.

Host is trying to acquire semaphore lock based on HW_SEM_RETRY_COUNT
value which is set to 10 by default. So host will loop for 10 times
trying to acquire lock before giving error msg "Failed to acquire HW
lock". Though this loop count of 10 is good enough with most of the
times but we have observed such failure msg in very few cases(~5 %).

Increase ACP_HW_SEM_RETRY_COUNT to avoid such issue and loop for a
significant time period before throwing error. We're setting newer
loop count to quite higher value of 10K but it's very unlikely that
it will loop for this count, since for most of the cases lock will
get acquired at much lesser loop iterations.
