1ARM AMBA Primecell SP805 Watchdog
2
3SP805 WDT is a ARM Primecell Peripheral and has a standard-id register that
4can be used to identify the peripheral type, vendor, and revision.
5This value can be used for driver matching.
6
7As SP805 WDT is a primecell IP, it follows the base bindings specified in
8'arm/primecell.txt'
9
10Required properties:
11- compatible:  Should be "arm,sp805" & "arm,primecell"
12- reg:         Should contain location and length for watchdog timer register
13- clocks:      Clocks driving the watchdog timer hardware. This list should be
14               2 clocks. With 2 clocks, the order is wdog_clk, apb_pclk
15               wdog_clk can be equal to or be a sub-multiple of the apb_pclk
16               frequency
17- clock-names: Shall be "wdog_clk" for first clock and "apb_pclk" for the
18               second one
19
20Optional properties:
21- interrupts:  Should specify WDT interrupt number
22- timeout-sec: Should specify default WDT timeout in seconds. If unset, the
23               default timeout is determined by the driver
24
25Example:
26	watchdog@66090000 {
27		compatible = "arm,sp805", "arm,primecell";
28		reg = <0x66090000 0x1000>;
29		interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;
30		clocks = <&wdt_clk>, <&apb_pclk>;
31		clock-names = "wdog_clk", "apb_pclk";
32	};
