Subject: [PATCH] dt-bindings: timer: sprd-timer: convert to YAML
Convert the Spreadtrum SC9860 timer bindings to DT schema.
Changes during conversion:
- rename file to match compatible
- add sprd,sc9860-suspend-timer which was previously undocumented
- minor grammar fix in description

-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>;
- };
