[PATCH v2] dt-bindings: timer: Convert faraday,fttmr010 to DT schema

[Rob Herring (Arm)]

Convert the Faraday fttmr010 Timer binding to DT schema format. Adjust
the compatible string values to match what's in use. The number of
interrupts can also be anywhere from 1 to 8. The clock-names order was
reversed compared to what's used.

v2:
 - Fix clock-names order in example

-Faraday Technology timer
-
-This timer is a generic IP block from Faraday Technology, embedded in the
-Cortina Systems Gemini SoCs and other designs.
-
-Required properties:
-
-- compatible : Must be one of
-  "faraday,fttmr010"
-  "cortina,gemini-timer", "faraday,fttmr010"
-  "moxa,moxart-timer", "faraday,fttmr010"
-  "aspeed,ast2400-timer"
-  "aspeed,ast2500-timer"
-  "aspeed,ast2600-timer"
-
-- reg : Should contain registers location and length
-- interrupts : Should contain the three timer interrupts usually with
-  flags for falling edge
-
-Optionally required properties:
-
-- clocks : a clock to provide the tick rate for "faraday,fttmr010"
-- clock-names : should be "EXTCLK" and "PCLK" for the external tick timer
-  and peripheral clock respectively, for "faraday,fttmr010"
-- syscon : a phandle to the global Gemini system controller if the compatible
-  type is "cortina,gemini-timer"
-
-Example:
-
-timer@43000000 {
-	compatible = "faraday,fttmr010";
-	reg = <0x43000000 0x1000>;
-	interrupts = <14 IRQ_TYPE_EDGE_FALLING>, /* Timer 1 */
-		   <15 IRQ_TYPE_EDGE_FALLING>, /* Timer 2 */
-		   <16 IRQ_TYPE_EDGE_FALLING>; /* Timer 3 */
-	clocks = <&extclk>, <&pclk>;
-	clock-names = "EXTCLK", "PCLK";
-};
