Hi,

This is v2 of my Avaota A1 SPI NAND enablement series.

Changes since v1:
- DT bindings (Krzysztof)
  - Moved "allOf:" block after "required:" block
  - Dropped "type:" from child node in conditional block
- Collected tags
- Link to v1:
  https://lore.kernel.org/linux-sunxi/20260227175157.2339758-1-wens@kernel.org/

This series enables the SPI NAND found on the Avaota A1 in Quad SPI
mode. The SPI driver already supports Dual SPI and Quad SPI, but the
bindings need to be updated to allow it.

Patch 1 updates the binding to allow Dual SPI and Quad SPI on the newer
SoCs. It also allows describing no TX or no RX available.

Patch 2 adds another set of pins for spi0 on the A523 SoC family. This
set is used for the SPI NAND on the Avaota A1 board.

Patch 3 enables the SPI NAND found on the board. No partition layout
is provided at the moment.


Please have a look.


Thanks
ChenYu

I'd have expected to take this one?

Normally you merge patches pretty quickly, so I thought maybe you weren't
going to take this one.

I can back it out if you want to take it through the SPI tree.


Thanks

I tend to leave a week or two if I think it's likely someone's going to
review.

Probably safer for conflicts.

Now backed out.

Thanks!

      https://git.kernel.org/broonie/misc/c/743956bb9990

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
