ARM: dts: armada-38x: Add generic compatible to UART nodes
PATCH 1/1 ARM: dts: armada-38x: Add generic compatible to UART nodes
Add generic compatible string "ns16550a" to serial port nodes of Armada 38x.
This makes it possible to use earlycon.
Fixes 0d3d96ab0059 ("ARM: mvebu: add Device Tree description of the Armada 380/385 SoCs")
