This is an updated version of something I wrote about 7 years ago.
Minimum support for R2D-plus and LANDISK.
I think R2D-1 will work if you add AX88796 to dts.
And board-specific functions and SCI's SPI functions are not supported.

v3 changes.
- Rewrite clk drivers.
- Added sh_tmu to OF support.
- Cleanup PCI stuff.
- Update sm501 and sm501fb OF support.
- Update devicetree and documents.

v2 changes.
- Rebasing v6,6-rc1
- re-write irqchip driver.
- Add binding documents.
- Cleanup review comment.

I tried to apply this series against both 6.5 and 6.6 and it unfortunately
fails. git also claims that one of the patches is empty.

Could you rebase your series against 6.7-rc1 once it's out?

In the mean time, I will add comments to the v3 series of your patches.

Adrian

Yes. I know that some changes are conflicting.
I was able to fix the comments for v3, so I will send a patch for v4
after importing v6.7-rc1.
