[PATCH 1/2] ASoC: amd: acp: add Cirrus SoundWire configs for ACP7.F

[PATCH 1/2] ASoC: amd: acp: add Cirrus SoundWire configs for ACP7.F

[Syed Saba Kareem]

From: Syed Saba Kareem <Syed.SabaKareem@amd.com>

Extend the ACP7.F SoundWire machine table with additional Cirrus Logic
codec configurations:
- CS42L43 jack + CS35L56 quad amp (L0+L1, L1)
- CS42L45 jack + CS35L63 stereo/quad amp (L0+L1 combinations)
- CS35L56 quad amp standalone (L1)
- Standalone CS42L43 / CS42L43B / CS42L45 jack (L0)

Add the corresponding endpoint, adr_device and link_adr descriptors for
the CS42L43/CS42L45 jack codecs and the CS35L56/CS35L63 amplifiers, with
speaker endpoints grouped for aggregated multi-amp playback. The CS42L45
entries reuse the CS42L43 endpoint array minus the speaker endpoint since
CS42L45 has no internal speaker path.

[PATCH 2/2] ASoC: amd: acp: add SoundWire speaker quirks for Dell platforms

[Syed Saba Kareem]

From: Syed Saba Kareem <Syed.SabaKareem@amd.com>

Add sof_sdw_quirk_table DMI entries for the Dell 0EF1, 0EF2, 0EF3, 0EF4,
0F12 and 0F13 platforms, setting the ASOC_SDW_CODEC_SPKR quirk so that
the SoundWire speaker amplifiers are enabled on these systems.
