1 * ARM SP805 Watchdog Timer (WDT) Controller
3 SP805 WDT is a ARM Primecell Peripheral and has a standard-id register that
4 can be used to identify the peripheral type, vendor, and revision.
5 This value can be used for driver matching.
7 As SP805 WDT is a primecell IP, it follows the base bindings specified in
11 - compatible : Should be "arm,sp805-wdt", "arm,primecell"
12 - reg : Base address and size of the watchdog timer registers.
13 - clocks : From common clock binding.
14 First clock is PCLK and the second is WDOGCLK.
15 WDOGCLK can be equal to or be a sub-multiple of the PCLK frequency.
16 - clock-names : From common clock binding.
17 Shall be "apb_pclk" for first clock and "wdog_clk" for the
21 - interrupts : Should specify WDT interrupt number.
