[PATCH v3 3/5] arm64: dts: realtek: Add irq mux to RTD129x

Andreas Färber
2017-10-17T12:47:05Z

Update UART nodes with interrupts.

Signed-off-by: Andreas F?rber <afaerber@suse.de>
---
v2 -> v3:
* Added nodes to rtd129x.dtsi instead of rtd1295.dtsi
* Adopted misc compatible string
* Renamed node label from irq_mux to misc_irq_mux for clarity

v1 -> v2:
* Rebased
