[PATCH v6 0/2] ASoC: Intel: Add Yoga Book RT5677 support

[Maurizio Casciano]

Hi,

This series adds the Cherry Trail machine driver and machine-table entry
needed by the Lenovo Yoga Book YB1-X91F/L with its RT5677 codec and
TS3A227E headset detector.

Only the SOF path is enabled. Legacy SST is deliberately not advertised
because it has not been validated on this hardware.

Changes in v6:
- Return clock-disable errors to DAPM callers.
- Propagate all headphone, speaker and ASRC GPIO/setup errors. Roll back
  the first speaker GPIO when the second update fails.
- Restore the mode-3 enable pulse and settling delay required by the
  external speaker boost amplifier, while checking every GPIO operation.
- Compact the SND_SOC_DAILINK_DEF() declarations and remove the redundant
  card comment.
- Restrict the driver and machine entry to SOF; remove the legacy SST
  firmware, board fields and conditional card naming.
- Remove snd_soc_fixup_dai_links_platform_name(). The card registers and
  all tested endpoints work without it.

Validation:
- W=1 build of cht_rt5677.o and soc-acpi-intel-cht-match.o.
- W=1 build and temporary load of snd-soc-sst-cht-rt5677.ko on the Yoga
  Book with Linux 7.2.0.
- PCM0 playback and capture.
- PCM1 deep-buffer playback.
- Manual GNOME Settings tests of both built-in speakers and microphone.
- No new kernel errors during the successful final hardware test.

The v6 series is sent as a fresh thread and Yauhen Kharuzhy is copied as
co-developer.
