Subject: [PATCH 3/3] drm/msm/mdp5: Disable pingpong autorefresh at tearcheck init
Date: Tue,  6 Apr 2021 23:47:26 +0200	[thread overview]
Message-ID: <20210406214726.131534-4-marijn.suijten@somainline.org> (raw)
In-Reply-To: <20210406214726.131534-1-marijn.suijten@somainline.org>

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>

If pp autorefresh is up (from bootloader splash), we will surely get
vblank and pp timeouts.  Ensure it is turned off.
