* 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.

+Example:
+ uart0: serial@70000000 {
+ compatible = "sprd,sc9838-uart",
+ "sprd,sc9836-uart";
+ reg = <0x000000 0x100>;
+ interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&ext_26m>;
+ status = "disabled";
