[PATCH 0/3] drm/rockchip: vop2: Add 8K support for RK3588 vop2

[Chaoyi Chen]

Hi,

This series adds support for 8K output on the RK3588 VOP2. HDMI is not
ready yet, but I believe @Sebastian and @Cristian might be interested in
this?

8K output on the RK3588 is done by splicing two VPs together, with VP0
outputting the left half of the screen and VP1 the right half. In
addition, 8K planes have to be split in half as well to stay within the
width limit of a single plane. Similarly, there are a few post-processing
details that need to be handled.

Note that splice mode is not only usable for 8K output. This means the
mode can be tested at 4K and even lower resolutions, by simply changing 
this one line:

-#define VOP2_MAX_VP_OUTPUT_WIDTH    4096
+#define VOP2_MAX_VP_OUTPUT_WIDTH    (3840 / 2) /* for 4K test */

And yes, this has been tested at 4K over HDMI on the RK3588 EVB1 :)
