[PATCH v2 0/2] ASoC/soundwire: revisit support for clock registers

[PATCH v2 0/2] ASoC/soundwire: revisit support for clock registers

[Bard Liao]

SoundWire clock base and scale registers are only supported for SDCA
devices. That's fine, but that leaves SoundWire 1.2 with optional
registers not supported. This is a corner case that needs to be supported.

The change is mainly on soundwire. But rt1318-sdw.c was applied to
ASoC tree recently and not in SoundWire tree yet. @Vinod, Are you good
if we go throutgh ASoC tree? Or @Mark can provide a tag and we can go
through SoundWire tree?

changes:
v2:
 - remove is_sdca flag from rt1318-sdw codec driver, too.

  ASoC/soundwire: remove is_sdca boolean property
  soundwire: enable optional clock registers for SoundWire 1.2 devices

[PATCH v2 1/2] ASoC/soundwire: remove is_sdca boolean property

[Bard Liao]

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

The Device_ID registers already tell us if a device supports the SDCA
specification or not, in hindsight we never needed a property when the
information is reported by both hardware and ACPI.

Hey Mark,

sound/soc/codecs/rt1318-sdw.c does not exist for me in sdw/next. Can I
get a tag for the changes merged into ASoC for this
