Binding for Cadence UART Controller
Required properties:
-- compatible : should be "cdns,uart-r1p8", or "xlnx,xuartps"
+- compatible :
+ Use "xlnx,xuartps","cdns,uart-r1p8" for Zynq-7xxx SoC.
+ Use "xlnx,zynqmp-uart","cdns,uart-r1p12" for Zynq Ultrascale+ MPSoC.
- reg: Should contain UART controller registers location and length.
- interrupts: Should contain UART controller interrupts.
- clocks: Must contain phandles to the UART clocks
