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";
};
