[PATCH 00/11] ASoC/soundwire: add initial support for SDCA

[PATCH 00/11] ASoC/soundwire: add initial support for SDCA

[Bard Liao]

We need to get rt712 version by reading SDCA version and functions.
This patch series adds initial support for SDCA and add a helper to tell
if the codec is RT712_VB.

This series may go via the ASoC tree with Vinod's Acked-by tag.

[PATCH 02/11] ASoC/soundwire: remove sdw_slave_extended_id

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

This structure is used to copy information from the 'sdw_slave'
structures, it's better to create a flexible array of 'sdw_slave'
pointers and directly access the information. This will also help
access additional information stored in the 'sdw_slave' structure,
such as an SDCA context.

This patch does not add new functionality, it only modified how the
information is retrieved.

[PATCH 03/11] ASoC: SDCA: add initial module

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Add new module for SDCA (SoundWire Device Class for Audio) support.
For now just add a parser to identify the SDCA revision and the
function mask.

Note that the SDCA definitions and related MIPI DisCo properties are
defined only for ACPI platforms and extracted with _DSD helpers. There
is currently no support for Device Tree in the specification, the
'depends on ACPI' reflects this design limitation. This might change
in a future revision of the specification but for SDCA 1.0 ACPI is the
only supported type of platform firmware.

The SDCA library is defined with static inline fallbacks, which will
allow for unconditional addition of SDCA support in common parts of
the code.

The design follows a four-step process:

1) Basic information related to Functions is extracted from MIPI DisCo
tables and stored in the 'struct sdw_slave'. Devm_ based memory
allocation is not allowed at this point prior to a driver probe, so we only
store the function node, address and type.

2) When a codec driver probes, it will register subdevices for each
Function identified in phase 1)

3) a driver will probe for each subdevice and addition parsing/memory
allocation takes place at this level. devm_ based allocation is highly
encouraged to make error handling manageable.

4) Before the peripheral device becomes physically attached, register
access is not permitted and the regmaps are cache-only. When
peripheral device is enumerated, the bus level uses the
'update_status' notification; after optional device-level
initialization, the codec driver will notify each of the subdevices so
that they can start interacting with the hardware.

Note that the context extracted in 1) should be arguably be handled
completely in the codec driver probe. That would however make it
difficult to use the ACPI information for machine quirks, and
e.g. select different machine driver and topologies as done for the
RT712_VB handling later in the series. To make the implementation of
quirks simpler, this patchset extracts a minimal amount of context
(interface revision and number/type of Functions) before the codec
driver probe, and stores this context in the scope of the 'struct
sdw_slave'.

The SDCA library can also be used in a vendor-specific driver without
creating subdevices, e.g. to retrieve the 'initialization-table'
values to write platform-specific values as needed.

For more technical details, the SDCA specification is available for
public downloads at https://www.mipi.org/mipi-sdca-v1-0-download

[PATCH 04/11] soundwire: slave: lookup SDCA version and functions

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Use SDCA helpers to get the basic information and store it in the
slave context. The information will be optionally be used in codec
drivers to register sub-devices for each Function.

When platforms are not based on ACPI the helpers do absolutely
nothing.

[PATCH 06/11] ASoC: rt712-sdca: detect the SMART_MIC function during the probe stage

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

We shouldn't do any devm_ based allocation in the io_init(), this need
to happen in the probe(). Luckily, we now have an SDCA helper to look
in ACPI tables if a SMART_MIC function is exposed.

FIXME: the registers are not well handled today, the regmap lists
registers which are not really supported in all platforms. The regmap
needs to throw an error if those registers are accessed without
existing.

[PATCH 07/11] ASoC: soc-acpi: introduce new 'machine check' callback

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

The existing machine_quirk() returns a pointer to a soc_acpi_mach
structure.
For SoundWire/SDCA support, we need a slightly different
functionality where a quirk function either validates or NACKs an
initial selection, based on additional firmware/DMI information.

In theory the dailinks are created based on the number of endpoints

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
