[PATCH v1 4/5] arm64: dts: mt7622: add bananapi BPI-R64 board

From: Ryder Lee
Date: Sat Aug 18 2018 - 12:03:35 EST


Add support for the bananapi R64 (BPI-R64) development board from
BIPAI KEJI. Detailed hardware information for BPI-R64 which could be
found on http://wiki.banana-pi.org/Banana_Pi_BPI-R64

Signed-off-by: Ryder Lee <ryder.lee@xxxxxxxxxxxx>
---
changes since v1:
- add missing sata nodes.
- fix pinctrl-0 for pcie@1,0.
- switch goio keys from polling mode to intterupt mode.
- add gpio-led nodes.
