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.

Why send this as one huge series?

These are the mailing lists that you have on CC:
linux-ide, devicetree, linux-kernel,
linux-renesas-soc, linux-clk, dri-devel,
linux-pci, linux-serial, linux-fbdev

I really think that you will be able to get all these changes accepted much
faster if you split this series in to one series per subsystem/mailing list.


Kind regards,
Niklas

Could you push your v7 version to your Gitlab [1] repository so I can fetch
it from there?

Thanks,

Thanks!

Sounds good! Maybe we can start merging the patches that contain fixes only
and that have already been reviewed. This way, we can reduce the overall size
of the series a bit.
