Pierre-Louis Bossart c7929b15b6 ASoC: soc-acpi: allow for partial match in parent name
To change the module dependencies and simplify Kconfigs, we need to
introduce new driver names (sof-audio-acpi-intel-byt and
sof-audio-acpi-intel-bdw), and move from an exact string match to a
partial one.

ASoC: soc-acpi: add helper to identify parent driver.
Intel machine drivers are used by parent platform drivers based on
closed-source firmware (Atom/SST and catpt) and SOF-based ones.

In some cases for ACPI-based platforms, the behavior of machine
drivers needs to be modified depending on the parent type, typically
for card names and power management.

An initial solution based on passing a boolean flag as a platform
device parameter was tested earlier. Since it looked overkill, this
patch suggests instead a simple string comparison to identify an SOF
parent device/driver.

ASoC: Intel: add codec name prefix to ACPI machine description
The current SOF machine driver adds a name prefix for each codec,
mainly to differentiate ALSA controls for left and right amplifiers.

This is a good idea, but the machine driver duplicates some of the
information that already exists in ACPI descriptors, so add those
prefixes there. Follow-up patches will make use of the information
encoded in these tables and remove duplication.

ASoC: soc-acpi: expand description of _ADR-based devices
For SoundWire, we need to know if endpoints needs to be 'aggregated'
(MIPI parlance, meaning logically grouped), e.g. when two speaker
amplifiers need to be handled as a single logical output.

We don't necessarily have the information at the firmware (BIOS)
level, so add a notion of endpoints and specify if a device/endpoint
is part of a group, with a position.

This may be expanded in future solutions, for now only provide a group
and position information.

Since we modify the header file, change all existing upstream tables
as well to avoid breaking compilation/bisect.

ASoC: soc-acpi: add _ADR-based link descriptors
For SoundWire support, we added a 'link_mask' to describe the PCB hardware
layout. This helped form a signature that can be used as a first-order way
of detecting the hardware and selecting the machine driver.

The concept of link_mask is however not enough. Some BIOS enable all links,
even when there are no devices physically connected. We can also see
variations with multiple devices attached on one link, or different types
of devices connected on the same link. To accurately represent the
hardware, we need to build static tables where each link exposes a list of
expected devices represented by the 64-bit _ADR field (which uniquely
identifies each device).

The new 'links' field is optional when the link_mask is sufficient to
represent a platform in a unique way.

The existing mechanism to support I2C devices is left as is, it'd be too
invasive to change the existing support for _HID and the notion of link is
not relevant either.

ASoC: Intel: skl-hda-dsp-generic: use snd-hda-codec-hdmi
Add support for using snd-hda-codec-hdmi driver for HDMI/DP
instead of ASoC hdac-hdmi. This is aligned with how other
HDA codecs are already handled.

When snd-hda-codec-hdmi is used, the PCM device numbers are
parsed from card topology and passed to the codec driver.
This needs to be done at runtime as topology changes may
affect PCM device allocation.

ASoC: soc-acpi: add link_mask field
When interfaces can be pin-muxed, static information from ACPI might
not be enough. Add information on which links needs to be enabled by
hardware/firmware for a specific machine driver to be selected.

When walking through the list of possible machines, links will be
checked, which implies that configurations where multiple links are
required need to be checked first.

Additional criteria will be needed later, such as which SoundWire
Slave devices are actually enabled, but for now this helps detect
between basic configurations.

ASoC: acpi: define common interface for machine driver configuration
The machine drivers may need information provided by the platform
driver.  Currently the information is passed using pdata specific to
each plaform driver. This prevents other drivers, such as SOF, from
reusing machine drivers directly.

Add a new structure which contains the required fields.

This proposal requires a bit more work on the platform side but this
generic interface helps reuse code directly.
