ASoC: cs35l56: Disable low-power hibernation mode
Do not allow the CS35L56 to be put into its lowest power
"hibernation" mode. This only affects I2C because "hibernation"
is already disabled on SPI and SoundWire.

Recent firmwares need a different wake-up sequence. Until
that sequence has been specified, the chip "hibernation" mode
must be disabled otherwise it can intermittently fail to wake.

THIS WILL NOT APPLY CLEANLY TO 6.5 AND EARLIER:
We will send a separate backport patch to stable.

ASoC: cs35l56: Add an ACPI match table
An ACPI ID has been allocated for CS35L56 ASoC devices so that they can
be instantiated from ACPI Device entries.

ASoC: cs35l56: Move shared data into a common data structure
The ASoC and HDA drivers have structures that contain some of the same
information - instead of maintaining two locations for this data the
drivers should share a common data structure as this will enable common
utility functions to be created.

The first step is to move the location of these members in the ASoC
driver.

ASoC: Switch two more i2c drivers back to use .probe()
The previous conversion back to .probe() applied in commit 9abcd24002bf
("ASoC: Switch i2c drivers back to use .probe()") was created based on
v6.3. Since then two more drivers were added which need to be convert
back in the same way before eventually .probe_new() can be dropped from
struct i2c_driver.

ASoC: cs35l56: Rework IRQ allocation
The irq member was being set before calling the init function and then
cs35l56_irq_request() was called only when the init was successful.
However cs35l56_release() calls devm_free_irq() when the irq member is
set and therefore if init() fails then this will cause an attempted free
of an unallocated IRQ.

Instead pass the desired IRQ number to the cs35l56_irq_request()
function and set cs35l56->irq only when it has been successfully
allocated.

ASoC: cs35l56: Add driver for Cirrus Logic CS35L56
The CS35L56 combines a high-performance mono audio amplifier, Class-H
tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost
converter supporting Class-H tracking.

Supported control interfaces are I2C, SPI or SoundWire.
Supported audio interfaces are I2S/TDM or SoundWire.

Most chip functionality is controlled by on-board ROM firmware that is
always running. The driver must apply patch/tune to the firmware
before using the CS35L56.
