[PATCH 0/3] Add basic HiHope RZ/G2M board support

[PATCH 0/3] Add basic HiHope RZ/G2M board support

[Biju Das]

The HiHope RZ/G2M board from HopeRun consists of main board
(HopeRun HiHope RZ/G2M main board) and sub board(HopeRun 
HiHope RZ/G2M sub board). The HiHope RZ/G2M sub board sits
below the HiHope RZ/G2M main board.

This series adds the device trees to describe the HW configuration
of the HiHope RZ/G2M, with some basic support.

This patch series based on linux-next next-20190528.
