[PATCH 01/10] media: mtk-vcodec: abstract firmware interface

From: Alexandre Courbot
Date: Wed May 20 2020 - 04:27:50 EST

From: Yunfei Dong <yunfei.dong@xxxxxxxxxxxx>

MT8183's codec firwmare is run by a different remote processor from
MT8173. While the firmware interface is basically the same, the way to
invoke it differs. Abstract all firmware calls under a layer that will
allow us to handle both firmware types transparently.
