[PATCH v5 0/6] Add Meson 8b / GXBB support to the IR driver

[Martin Blumenstingl]

Newer Amlogic platforms (Meson 8b and GXBB) use a slightly different
register layout for their Infrared Remoete Controller. The decoder mode
is now configured in another register. Without the changes to the
meson-ir driver we are simply getting incorrect "durations" reported
from the hardware (because the hardware is not in time measurement aka
software decode mode).

This problem was also noticed by some people trying to use this on an
ODROID-C1 and ODROID-C2 - the workaround there (probably because the
datasheets were not publicy available yet at that time) was to switch
to ir_raw_event_store_edge (which leaves it up to the kernel to measure
the duration of a pulse). See [0] and [1] for the corresponding
patches.

Changes in v5:
- changed pin function and group names to remote_input_ao so they match
  with the datasheet
