Subject: [PATCH 11/13] arm64: dts: qcom: msm8916-samsung-gt5: Add sound and
modem
From: Jasper Korten <jja2000@...il.com>
Enable sound and modem for the Samsung Galaxy Tab A 2015 tablets.
The setup is similar to most MSM8916 devices, i.e.:
- QDSP6 audio
- Headphones/microphones via digital/analog codec in
MSM8916/PM8916. Earpiece exists on samsung-gt58 only.
- WWAN Internet via BAM-DMUX
except:
- gt510: Stereo Maxim MAX98357A codecs for speaker on Quaternary MI2S
- gt58: Mono NXP TFA9895 codec for speaker on Quaternary MI2S
- For some reason connected to GPIOs where no hardware I2C
controller is available -> need to use i2c-gpio
- Samsung-specific audio jack detection (not supported yet)
