The Lenovo Yoga Book YB1-X91F/L uses a Cherry Trail SSP2 connection to
an RT5677 codec, with board-specific amplifier, headphone and headset
detector wiring.  Add the machine driver, the SST machine-table match,
and the SOF topology filename used by the corresponding external SOF
topology.

The companion platform/x86 series supplies the TS3A227E device and codec
GPIO lookup entries.  The sof-cht-rt5677.tplg topology is maintained in
the SOF project and must be merged and distributed separately.

With the matching topology installed, the Yoga Book reaches the SOF
card-registration and stream setup path.  End-to-end playback and
capture acceptance is not complete, so this is posted as an RFC.

Hello,

Unless I'm missing something, this looks like a resend of a patchset 
from earlier this year [1]. Previous owner of the subject, Yauhen 
Kharuzhy, is not even CC'ed here. I do not see any of the review points 
addressed here, moreover, I see a regression when compared to v3 from June.

Hiding behind RFC (not v4) is a weird move when viewed in context of 
CHT. The configuration is mature, CHT is over 12 years old. With basic 
playback/capture not enabled, does the review make sense?

Kind regards,
Czarek

You are right. Posting this as a new RFC, omitting Yauhen from CC, and not
making the relationship to his v3 explicit were mistakes.

I replaced the RFC with a versioned series based on Yauhen's work, restored
his copyright and provenance, and completed playback and capture validation
on the YB1-X91L. The follow-up v5 also restores Yauhen's Co-developed-by and
Signed-off-by trailers on both patches and addresses Mark's v4 review.

Thank you for pointing this out.

Maurizio

Hi Cezary,

Thank you for the review. I addressed your feedback and sent the revised
v4 series here:

https://lore.kernel.org/linux-sound/20260827072517.1401173-1-mauriziocasciano7@gmail.com/

The driver is now named generically for Cherry Trail RT5677 systems,
uses per-device card, DAI-link and component copies, allocates the jack
separately with the device lifetime, and unwinds MCLK on the PLL and
sysclk error paths. I also documented the ASRC clock selections and
combined the complete SST/SOF machine entry into the series.

The v4 sources passed sparse and a clean kernel package build. They were
also tested on the Yoga Book YB1-X91L; playback and capture passed, and
the GNOME Settings speaker and microphone tests passed physical
verification.

Thanks,
Maurizio
