Enable sound and modem on most of the MSM8916/MSM8939
smartphones/tablets supported upstream by:
- Adding the BAM-DMUX DT nodes to msm8939.dtsi for WWAN Internet
- Adding the QDSP6 DT nodes to both msm8916.dtsi and msm8939.dtsi.
This is needed because audio must be routed through the QDSP6
services provided by the modem firmware when the modem is active.
- Setting up the sound/codec related nodes for all the devices.
Most of the sound/modem setup is very similar on all MSM8916/MSM8939
devices because the device-specific details are abstracted by the modem
firmware. Reduce duplication by adding "msm8916-modem-qdsp6.dtsi" which
contains most of the common definitions. The board-specific DT part is
limited to extra codecs or board-specific sound setup.
With this patch set, the following functionality works on most
MSM8916/MSM8939 devices supported upstream:
- Sound: Speaker/earpiece/headphones/microphones
- Modem: Calls, SMS, WWAN Internet (e.g. with ModemManager)
And with extra pending patches also:
- Voice call audio
- GPS
These patches have been contributed by different people and have been
used/tested in postmarketOS for several years. Until now they had to
wait for other changes to be upstreamed (QDSP6 audio support for
MSM8916, dynamic reserved memory, ...).

BAM DMUX is used as the network interface to the modem. This is copied
as-is from msm8916.dtsi.
