[PATCH v2 7/8] arm64: dts: renesas: initial Eagle board device tree

[Sergei Shtylyov]

[-- Attachment #1: arm64-dts-renesas-initial-Eagle-board-device-tree.patch --]
[-- Type: text/plain, Size: 2651 bytes --]

Add the initial device  tree for  the R8A77970 SoC based Eagle board.
The board has 1 debug serial port (SCIF0); include support for it,
so that the serial console can work.

Based on the original (and large) patch by Vladimir Barinov
