Protection domain mapper is a QMI service providing mapping between
'protection domains' and services supported / allowed in these domains.
For example such mapping is required for loading of the WiFi firmware or
for properly starting up the UCSI / altmode / battery manager support.
The existing userspace implementation has several issue. It doesn't play
well with CONFIG_EXTRA_FIRMWARE, it doesn't reread the JSON files if the
firmware location is changed (or if the firmware was not available at
the time pd-mapper was started but the corresponding directory is
mounted later), etc.
However this configuration is largely static and common between
different platforms. Provide in-kernel service implementing static
per-platform data.
NOTE: this is an RFC / RFC, the domain mapping data might be inaccurate
(especially for SM6xxx and SC7xxx platforms), which is reflected by
several TODO and FIXME comments in the code.
Changes since RFC v1:
- Swapped num_domains / domains (Konrad)
- Fixed an issue with battery not working on sc8280xp
- Added missing configuration for QCS404
