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.

You can get it working with qemu found here.
https://gitlab.com/yoshinori.sato/qemu/-/tree/landisk

v4 changes.
- cpg-sh7750: use clk-divider and clk-gate.
- pci-sh7751: unified header files to old PCI driver.
- irq-renesas-sh7751: IPR registers direct mapping.
- irq-renesas-sh7751irl: useful register bit mapping.
- sm501 and sm501fb: re-write dt parser.
- j2_minus: fix build error.
- dt-binding schema: fix some errors.
- *.dts: cleanup.

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.

Thanks a lot for the updated version!

Unfortunately, I still cannot download this series with the "b4" utility
for some reason. Can you tell how you generated and sent the patches?

Thanks,
Adrian

Never mind. It was an issue on my side, your patch set is fine and applies without
problems on top of v6.7-rc1. Will try later this week whether it still boots on my
SH7785LCR.
