Rockchip RK3528 is a quad-core ARM Cortex-A53 SoC designed for
multimedia application. This series add a basic device tree with CPU,
interrupts and UART nodes for it and is able to boot into a kernel with
only UART console.

Has been tested on Radxa E20C board[1] with vendor U-boot, successfully
booted into initramfs with this log[2].

Ping on this thread. Is it possible to get this merged in v6.12? Or
anything else I need to do?

Thanks for your time.

sadly nope. From a timeline point of view things should ideally be in the
Rockchip tree by -rc6 . Which then move to the soc tree and from there
to Linus' tree.

There is this rule that all new development for a -rc1 kernel should be
present in linux-next _before_ the merge-window opens.

The thing we need to figure out for your series is the uart binding,
because that _should_ go through the tree handling serial drivers.
Greg is in your cc list but with the amount of mail he gets, I don't
think he has single-parts of patch series on his radar.

So I guess the easiest way would be to send the uart-binding from patch 1
as a completely separate patch with adapted Cc list, so that it's obvious
this should go through the serial tree.

Yeah, I missed this as it was part of a larger series.

Yes, please just send that one patch and I can pick it up.

Will do it, thanks for the suggestion.

Thanks for your reply.
