-* ARM SP805 Watchdog Timer (WDT) Controller
-
-SP805 WDT is a ARM Primecell Peripheral and has a standard-id register that
-can be used to identify the peripheral type, vendor, and revision.
-This value can be used for driver matching.
-
-As SP805 WDT is a primecell IP, it follows the base bindings specified in
-'arm/primecell.txt'
-
-Required properties:
-- compatible : Should be "arm,sp805-wdt", "arm,primecell"
-- reg : Base address and size of the watchdog timer registers.
-- clocks : From common clock binding.
- First clock is PCLK and the second is WDOGCLK.
- WDOGCLK can be equal to or be a sub-multiple of the PCLK frequency.
-- clock-names : From common clock binding.
- Shall be "apb_pclk" for first clock and "wdog_clk" for the
- second one.
-
-Optional properties:
-- interrupts : Should specify WDT interrupt number.
-
-Examples:
-
- cluster1_core0_watchdog: wdt@c000000 {
- compatible = "arm,sp805-wdt", "arm,primecell";
- reg = <0x0 0xc000000 0x0 0x1000>;
- clocks = <&clockgen 4 3>, <&clockgen 4 3>;
- clock-names = "apb_pclk", "wdog_clk";
- };
