[RFC PATCH v3 00/35] Device Tree support for SH7751 based board

[Yoshinori Sato <ysato@users.sourceforge.jp>]

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.
