[x] Found how to power up RT5677 codec (now it doesn't available via I2C but should be at I2C1, 0x2c).
[x] Write ACPI match and board support code for Intel Cherry Trail and RT5677 combination (there is first version exist)
[x] Add support for TS3A227E accessory detector and configuration switch (there is a driver in mainline kernel but Yoga Book doesn't have separated ACPI entry for this chip). I2C1, 0x3b.

Hi. I almost get the audio works (I believe). Only thing that I need is the alsa ucm config. can be found on internet but all of them won't work. always stuck at this error

ALSA lib main.c:438:(execute_sequence) unable to execute cset 'name='Speaker Switch' on'

ALSA lib main.c:1712:(set_verb_user) error: failed to initialize new use case: HiFi

alsaucm: error failed to set _verb=HiFi: No such file or directory

Not yet but almost, I planned to port the driver from android kernel and make the loadable module, but RN I'm using kernel 5.1, soon will move to 5.1.16 (under the 5.1.16)

Thank. Are looking forward to.

FYI a little bit off topic, recently the Front facing camera (ov2740) just has the driver in latest kernel source.

Sound playback works, microphones still not tested (please create separated issue if recording doesn't work).
