[PATCH 1/3] wdt: sunxi: Introduce a new compatible for the A10 and A31

[Maxime Ripard]

For historical reasons, the Allwinner A10 compatibles are not following the
patterns used for this other Allwinner SoCs.

Introduce a new compatible following the usual pattern, and deprecate the olders.

 Required properties:
 
-- compatible : should be "allwinner,<soc-family>-wdt", the currently supported
-  SoC families being sun4i and sun6i
+- compatible : should be either "allwinner,sun4i-a10-wdt" or
+               "allwinner,sun6i-a31-wdt" (deprecated:
+               "allwinner,sun4i-wdt", "allwinner,sun6i-wdt")
 - reg : Specifies base physical address and size of the registers.
 
 Example:
 
 wdt: watchdog at 01c20c90 {
-	compatible = "allwinner,sun4i-wdt";
+	compatible = "allwinner,sun4i-a10-wdt";
 	reg = <0x01c20c90 0x10>;
