[PATCH v2 08/14] arm64: dts: qcom: msm8916-alcatel-idol347: Add sound and modem

From: Stephan Gerhold
Date: Tue Oct 03 2023 - 09:19:17 EST

From: Vincent Knecht <vincent.knecht@xxxxxxxxxx>

Enable sound and modem for the Alcatel Idol 3 (4.7"). The setup is
similar to most MSM8916 devices, i.e.:

- QDSP6 audio
- Microphones via digital/analog codec in MSM8916/PM8916
- WWAN Internet via BAM-DMUX

except:

- Stereo NXP TFA9890 codecs for speakers on Quaternary MI2S
- These are also used as earpieces at the top/bottom.
- Asahi Kasei AK4375 headphone codec on Secondary MI2S
-> Primary MI2S is not used for playback

There are some trivial conflicts unless
https://lore.kernel.org/linux-arm-msm/20230921-msm8916-rmem-fixups-v1-3-34d2b6e721cf@xxxxxxxxxxx/
is applied first. But given that there are important fixups for the
dynamic reserved memory changes in that series it should preferably
get applied before this one anyway.
