Subject[PATCH v7 7/7] arm64: dts: mediatek: Initial mt8365-evk support
Date
From: Fabien Parent <fparent@baylibre.com>

This adds minimal support for the Mediatek 8365 SOC and the EVK reference
board, allowing the board to boot to initramfs with serial port I/O.

Signed-off-by: Fabien Parent <fparent@baylibre.com>
[bero@baylibre.com: Removed parts depending on drivers that aren't upstream yet, cleanups, add CPU cache layout, add systimer, fix GIC]
Signed-off-by: Bernhard Rosenkränzer <bero@baylibre.com>
Tested-by: Kevin Hilman <khilman@baylibre.com>
