From: Jonathan Albrieux <jonathan.albri...@gmail.com>
Enable sound and modem for the Longcheer L8910 (BQ Aquaris X5).
The setup is similar to most MSM8916 devices, i.e.:
- QDSP6 audio
- Earpiece/headphones/microphones via digital/analog codec in
MSM8916/PM8916
- Audio jack detection via analog codec in PM8916
- WWAN Internet via BAM-DMUX
except:
- Awinic AW8738 connected to HPH_R (headphones) output of the analog
codec. Note that unlike for wingtech-wt88047 there is no analog
switch that would allow disabling output via the headphone jack
when the speaker is enabled.
