The ACP7.0 SoundWire machine table did not cover boards that combine TI
TAS2783 smart amplifiers on SoundWire link 0 with a Realtek RT712-VB
codec on link 1.  In addition, the TAS2783 SoundWire codec driver was
not selected by the AMD legacy SoundWire machine config, so it was not
built for these platforms.

Select SND_SOC_TAS2783_SDW from SND_SOC_AMD_LEGACY_SDW_MACH so the
TAS2783 SoundWire codec driver is built together with the AMD legacy
(no-DSP) SoundWire machine.

Add a new link/address map, acp70_tas2783a_l0_rt712_vb_l1, describing
the TAS2783 amplifiers on link 0 and the RT712-VB codec on link 1, and
register a corresponding entry in snd_soc_acpi_amd_acp70_sdw_machines[].
The entry uses snd_soc_acpi_amd_sdca_is_device_rt712_vb() as its
machine_check callback so it only matches platforms that actually
expose the RT712-VB device.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.3

Thanks!

[1/1] ASoC: amd: acp: enable TAS2783 and add RT712-VB SoundWire machine
      https://git.kernel.org/broonie/sound/c/28114992dd2f

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
