+Spreadtrum timers
+
+The Spreadtrum SC9860 platform provides 3 general-purpose timers.
+These timers can support 32bit or 64bit counter, as well as supporting
+period mode or one-shot mode, and they are can be wakeup source
+during deep sleep.
+
+Required properties:
+- compatible: should be "sprd,sc9860-timer" for SC9860 platform.
+- reg: The register address of the timer device.
+- interrupts: Should contain the interrupt for the timer device.
+- clocks: The phandle to the source clock (usually a 32.768 KHz fixed clock).
+
+Example:
+ timer@40050000 {
+ compatible = "sprd,sc9860-timer";
+ reg = <0 0x40050000 0 0x20>;
+ interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&ext_32k>;
+ };
