Thanks, I noticed this the other day as well.

Btw, since all 3 files are null-patches, they could be extracted from a .patch and be put bare in the dt_uboot/dt_upstream_rockchip/defconfig folders via the 000.patching_config.yaml magic.

[rpardini]

(I expect the r76s to land upstream soon enough, so the whole thing might go away soon. I'd just rather keep v2026.01 null-patch-free if possible)

[EvilOlaf]

Perhaps @SuperKali wants to take care of that?

[rpardini]

Might wanna hold off a bit, as torvalds/linux@7fee888 just landed in 6.19-rc1 -- might take a while until u-boot rebases dts/upstream onto it

@EvilOlaf I missed this PR, I just read it now, let's wait as @rpardini says.
