[PATCH v3 25/26] drm: sun4i: de33: fmt: add Display Engine 3.3 (DE33) support
From: Ryan Walklin <hidden>
Date: 2024-08-17 23:08:42
Also in:
dri-devel, linux-clk, linux-devicetree, linux-sunxi
Subsystem:

From: Jernej Skrabec <jernej.skrabec@gmail.com> Like the DE3, the DE33 has a FMT (formatter) module, which provides YUV444 to YUV422/YUV420 conversion, format re-mapping and color depth conversion, although the DE33 module appears significantly more capable, including up to 4K video support. Add support for the DE33.
