1 ARM AMBA Primecell SP805 Watchdog
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" & "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
17 - clock-names: Shall be "wdog_clk" for first clock and "apb_pclk" for the
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
