From 3c5b218c3606840048a9cacae4a29692ab1afc7c Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Mon, 29 Nov 2021 19:26:29 +0100 Subject: [PATCH] media: hantro: move postproc enablement for old cores 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.
