Subject: [PATCH 06/10] media: mtk-vcodec: venc: specify supported formats per-chip
Date: Wed, 20 May 2020 17:27:19 +0900	[thread overview]
Message-ID: <20200520082723.96136-7-acourbot@chromium.org> (raw)
In-Reply-To: <20200520082723.96136-1-acourbot@chromium.org>

Different chips have different supported bitrate ranges. Move the list
of supported formats to the platform data, and split the output and
capture formats into two lists to make it easier to find the default
format for each queue.
