[RFC PATCH v2 00/30] Device Tree support for SH7751 based board

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.

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