Subject[PATCH v2 1/6] Documentation: DT: Consolidate SP805 binding docs
Date
Consolidate two SP805 binding documents "arm,sp805.txt" and
"sp805-wdt.txt" into "arm,sp805.txt" that matches the naming of the
desired compatible string to be used

ARM AMBA Primecell SP805 Watchdog

+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" & "arm,primecell"
- reg: Should contain location and length for watchdog timer register.
-- interrupts: Should contain the list of watchdog timer interrupts.
- clocks: clocks driving the watchdog timer hardware. This list should be 2
- clocks. With 2 clocks, the order is wdogclk clock, apb_pclk.
+ clocks. With 2 clocks, the order is wdog_clk, apb_pclk.
+ wdog_clk can be equal to or be a sub-multiple of the apb_pclk frequency
+- clock-names : Shall be "wdog_clk" for first clock and "apb_pclk" for the
+ second one.
+
+Optional properties:
+- interrupts : Should specify WDT interrupt number.

Example:
watchdog@66090000 {
compatible = "arm,sp805", "arm,primecell";
reg = <0x66090000 0x1000>;
interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&apb_pclk>,<&apb_pclk>;
- clock-names = "wdogclk", "apb_pclk";
+ clocks = <&wdt_clk>, <&apb_pclk>;
+ clock-names = "wdog_clk", "apb_pclk";

-As SP805 WDT is a primecell IP, it follows the base bindings specified in

-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
