Nikita Travkin 1ab407193d arm64: dts: qcom: msm8916-longcheer-l8150: Add sound and modem
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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
