[PATCH 00/43] ep93xx device tree conversion
This series aims to convert ep93xx from platform to full device tree support.
Tested on ts7250 64 RAM/128 MiB Nand flash, edb9302.
Thank you Linus and Arnd for your support, review and comments, sorry if i missed something - these series are quite big for me.
Big thanks to Alexander Sverdlin for his testing, support, review, fixes and patches.

Thanks a lot for your continued work. I can't merge any of this at the moment since the upstream merge window just opened, but I'm happy to take this all through the soc tree for 6.5, provided we get the sufficient Acks from the subsystem maintainers. Merging it through each individual tree would take a lot longer, so I hope we can avoid that.

I didn't get entire patchset and cover letter does not mention dependencies, but usually there shouldn't be such. Maybe for the next versions this should be split per subsystem?

Clearly the last patch that removes the board files depends on all the previous patches, but I assume that the other ones are all independent.
We don't do complete conversions from boardfiles to DT that often any more, but in the past we tended to do this through a cross- subsystem branch in the soc tree, which helps do it more quickly and is less work for Nikita. In this case, I would make it a separate top-level branch in the soc tree.
If anyone strongly feels that the patches should go through the subsystem trees here, we'll take the longer path and do the changes separately, with the boardfile removal coming a release later.

Neat, I'd say let's merge this for 6.5 once the final rough edges are off. The DT bindings should be easy to fix.
This is a big patch set and the improvement to the ARM kernel it brings is great, so I am a bit worried about over-review stalling the merged. If there start to be nitpicky comments I would prefer that we merge it and let minor comments and "nice-to-haves" be addressed in-tree during the development cycle.
I encourage you to use b4 to manage the patch series if you have time to learn it, it could help you: https://people.kernel.org/monsieuricon/sending-a-kernel-patch-with-b4-part-1

I'm really not enthusiastic about the SPI bindings being merged as-is.

Agree, the bindings are more important than the code IMO, they tend to get written in stone.

Thank you Linus and Arnd for your support, review and comments, sorry if i missed something - these series are quite big for me.
Big thanks to Alexander Sverdlin for his testing, support, review, fixes and patches.
If anyone is interested I still have a TS-7300 board [1] that is fully functional and could be sent out to a new home.
