Subject[PATCH v2 0/4] media: meson: vdec: add g12a platform
Date
This patchset adds support for the current Amlogic Video Decoder
driver for the Amlogic G12A & compatible SoCs.

The bindings are converted to YAML and dt-schemes to ease validation
of the bindings and the Amlogic DT.

Then support is added for the currently supported MPEG1 & MPEG2 decoders
and additional clock for upcoming HEVC/VP9 decoder support.

M2M Decoder compliance is handled in a separate patchset at [1].
