* Spreadtrum serial UART
Required properties:
-- compatible: must be "sprd,sc9836-uart"
+- compatible must contain:
+ * "sprd,sc9836-uart" for SC9836 and all Spreadtrum SoCs
+ This also can be specific with:
+ * "sprd, sc9860-uart" for SC9860
+
- reg: offset and length of the register set for the device
- interrupts: exactly one interrupt specifier
- clocks: phandles to input clocks.
