Subject: [PATCH 3/9] drm/ast: Don't clear base address and offset with default values
Date: Mon, 28 Oct 2019 16:49:22 +0100 [thread overview]
Message-ID: <20191028154928.4058-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20191028154928.4058-1-tzimmermann@suse.de>
The content of the base-address and offset registers are state of
the primary plane. Clearing it to default values will interfere with
plane functions for atomic mode setting.
