Subject: [PATCH v2 11/14] drm/imx: dc-ed: Drop initial source selection
Date: Tue, 23 Sep 2025 10:08:01 +0800 [thread overview]
Message-ID: <20250923-imx8-dc-prefetch-v2-11-5d69dc9ac8b5@nxp.com> (raw)
In-Reply-To: <20250923-imx8-dc-prefetch-v2-0-5d69dc9ac8b5@nxp.com>
It's unnecessary to set initial ExtDst source selection because KMS
driver would do that when doing atomic commits. Drop the selection.
This is needed as a preparation for reading ExtDst source selection
when trying to disable CRTC at boot in an upcoming commit.
