[-- 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
<vladimir.barinov-M4DtvfQ/ZS1MRgGoP+s0PdBPR1lH4CV8@public.gmane.org>.

Nitpicking: the schematics say 16.6666 MHz
At 100 ppm accuracy that's the same, though.

I don't think that's really needed, as the difference is smaller than the
accuracy anyway.
