    1 Faraday Technology timer
    2 
    3 This timer is a generic IP block from Faraday Technology, embedded in the
    4 Cortina Systems Gemini SoCs and other designs.
    5 
    6 Required properties:
    7 
    8 - compatible : Must be one of
    9   "faraday,fttmr010"
   10   "cortina,gemini-timer", "faraday,fttmr010"
   11   "moxa,moxart-timer", "faraday,fttmr010"
   12   "aspeed,ast2400-timer"
   13   "aspeed,ast2500-timer"
   14   "aspeed,ast2600-timer"
   15 
   16 - reg : Should contain registers location and length
   17 - interrupts : Should contain the three timer interrupts usually with
   18   flags for falling edge
   19 
   20 Optionally required properties:
   21 
   22 - clocks : a clock to provide the tick rate for "faraday,fttmr010"
   23 - clock-names : should be "EXTCLK" and "PCLK" for the external tick timer
   24   and peripheral clock respectively, for "faraday,fttmr010"
   25 - syscon : a phandle to the global Gemini system controller if the compatible
   26   type is "cortina,gemini-timer"
   27 
   28 Example:
   29 
   30 timer@43000000 {
   31         compatible = "faraday,fttmr010";
   32         reg = <0x43000000 0x1000>;
   33         interrupts = <14 IRQ_TYPE_EDGE_FALLING>, /* Timer 1 */
   34                    <15 IRQ_TYPE_EDGE_FALLING>, /* Timer 2 */
   35                    <16 IRQ_TYPE_EDGE_FALLING>; /* Timer 3 */
   36         clocks = <&extclk>, <&pclk>;
   37         clock-names = "EXTCLK", "PCLK";
   38 };
