[v2,05/14] arm64: dts: qcom: msm8916-samsung-a2015: Add sound and modem
Commit Message
Enable sound and modem for the Samsung A2015 based devices (A3, A5, E5,
E7, Grand Max). The setup is similar to most MSM8916 devices, i.e.:
- QDSP6 audio
- Earpiece/headphones/microphones via digital/analog codec in
MSM8916/PM8916
- WWAN Internet via BAM-DMUX
except:
- NXP TFA9895 codec for speaker on Quaternary MI2S
- Samsung-specific audio jack detection (not supported yet)
[Lin: Add e2015 and grandmax]
