[PATCH v2 0/4] Add support Yuridenki-Shokai Kakip board

[Nobuhiro Iwamatsu]

Hi all,

This patch series add basic support for Yuridenki-Shokai[0] Kakip board[1] based
on R9A09G057H48.
And this series supports the following:

  - Memory
  - Input clocks
  - Pin Control
  - SCIF
  - OSTM0 - OSTM7
  - SDHI0

v2:
  - Fix the rule of binding for boards.
    kakip board uses r9a09g057h48 only.
  - Drop bootargs from chosen.
  - Fix binding name for regulators.
  - Fix the name style of the regulator.
  - Use DTS coding style.

Best regatrds,
  Nobuhiro
