2
3This timer is a generic IP block from Faraday Technology, embedded in the
4Cortina Systems Gemini SoCs and other designs.
5
6Required 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
20Optionally 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
28Example:
29
30timer@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};
