Subject: [PATCH 13/13] arm64: dts: qcom: msm8939-samsung-a7: Add sound and
 modem

From: "Lin, Meng-Bo" <linmengbo0689@...tonmail.com>

Enable sound and modem for the Samsung A7. 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 for the same differences as the MSM8916-based Samsung A2015
devices:

 - NXP TFA9895 codec for speaker on Quaternary MI2S
 - Samsung-specific audio jack detection (not supported yet)
