Enable sound and modem for the Longcheer L8150 (e.g. Wileyfox Swift).
The setup is similar to most MSM8916 devices, i.e.:
- QDSP6 audio
- Speaker/earpiece/headphones/microphones via digital/analog codec
in MSM8916/PM8916
- Audio jack detection via analog codec in PM8916
- WWAN Internet via BAM-DMUX
except:
- The mpss firmware region must be relocated to a different address.
This is because the wcnss firmware is not relocatable for some
reason. The mpss firmware is too large to avoid overlap with wcnss
when placed at the default address (0x86800000).
Surprisingly the vendor kernel does not handle this. The firmware
regions end up overlapping there and somehow this does not explode.
We try to handle this more safely by relocating the mpss region to
the first higher address that is working correctly: 0x8e800000.

I would say the same as on PATCH 07/13 here:

Yes, "e.g." is indeed correct here. AFAIK the MSM8916-based Android One
devices (aka "google-seed") are also based on the Longcheer L8150. They
are available under names like "Cherry Mobile One G1", "i-mobile IQ II",
and "General Mobile 4G". They are also covered by this device tree.
Thanks,
Stephan
