Subject: [PATCH 4/7] media: hantro: move postproc enablement for old cores
Date: Mon, 22 Nov 2021 19:46:59 +0100	[thread overview]
Message-ID: <20211122184702.768341-5-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20211122184702.768341-1-jernej.skrabec@gmail.com>

Older G2 cores, like that in Allwinner H6, seem to have issue with
latching postproc register values if this is first thing done in job.
Moving that to the end solves the issue.
