If your primary focus is to only test eMMC support for the Orange Pi 5
Max, then apply the patches on top linux-rockchip for-next.
https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/log/?h=for-next
That generated DTB should be able to run against an older kernel since
the Orange Pi 5 Plus already works.

It's complicated since the HDMI Bridge support is in the pipeline for
6.13-rc1 but it goes through different trees..
The driver itself is merged into drm-misc next

Where as the DTS updates are in linux-rockchip branch

Also, regarding v3, I rebased on top of linux-rockchip for-next to
include the updates for HDMI and GPU on the Orange Pi 5 Plus.

For my development testing, I used Collabora's rk3588-test development
branch, so all the needed patches were already in one place (since
they test on a Radxa Rock 5B with the RK3588).
https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/commits/rk3588-test/?ref_type=heads

So for v3, I had to first cherry-pick the Orange Pi 5 Plus changes
from linux-rockchip for-next.

Note: for v3 I held off on adding the USB 3 support for the Max, I was
going to let the Orange Pi 5 Plus finish their USB 3 submission before
trying to refactor the common DTS nodes.
