Subject: [PATCH v2 9/9] ARM: dts: aspeed: Clean up UART nodes
- Shorten size of reg property so it covers only the implemented
registers
- Add VUART compatible, and change node name to serial@
- Remove outdated current-speed property. Different bootloaders use
different speeds, so this is no longer helpful
Signed-off-by: Joel Stanley <joel@....id.au>
---
v2:
- move node reordering to seperate patch
- fix vuart node name
- actually remove current-speed from g4
