Subject: [PATCH v2 1/3] drm/sun4i: Unify sun8i_*_layer structs
Date: Sat, 24 Feb 2024 16:05:58 +0100	[thread overview]
Message-ID: <20240224150604.3855534-2-megi@xff.cz> (raw)
In-Reply-To: <20240224150604.3855534-1-megi@xff.cz>

From: Ondrej Jirman <megi@xff.cz>

These structs are identical, use a single struct to represent private
data for the DRM plane. This is a preparation for configuring layer
routing from the CRTC (mixer) instead of current approach of setting
up routing from individual layer's atomic_update callback.
