Sorry, I failed to explain properly what was expected.

dts/upstream should never be touched except with 
dts/update-dts-subtree.sh script.

Sadly, your board is not supported in v6.9 yet, only in the upcoming 
v6.10 :/

So we have two options, we keep the dts in arch/arm/dts/ like you used 
to do, until we merge v6.10 dts in U-Boot (probably for v2024.10?), or 
we cherry-pick the changes for your board with dts/update-dts-subtree.sh 
script, see the instructions in the docs Tom has started writing: 
https://lore.kernel.org/u-boot/20240517174930.1028063-2-trini@konsulko.com/. 
I would very much like to see someone starting to look into the second 
option :)

However... it seems we'll likely need to also cherry-pick patches for 
the GPU (should probably be straightforward as nothing would be using 
the GPU anyway in U-Boot) and the USBDP PHY... but this one we would 
need to update all -u-boot.dtsi for rk3588(s) boards that have it 
already to make it use the new label/DT, make sure that the driver still 
works... etc. Maybe not a small feat, but someone will have to do it at 
some point anyway :)

You'd be the first one to do this cherry-picking into dts/upstream, so 
it'd be really interesting to us if you could provide feedback on what 
is unclear/not working, etc... so we can update the documentation or fix 
tools if they were to be insufficient.

Looking forward to your next patch,
Cheers,
Quentin
