-SPRD Hardware Spinlock Device Binding
--------------------------------------
-
-Required properties :
-- compatible : should be "sprd,hwspinlock-r3p0".
-- reg : the register address of hwspinlock.
-- #hwlock-cells : hwlock users only use the hwlock id to represent a specific
-	hwlock, so the number of cells should be <1> here.
-- clock-names : Must contain "enable".
-- clocks : Must contain a phandle entry for the clock in clock-names, see the
-	common clock bindings.
-
-Please look at the generic hwlock binding for usage information for consumers,
-"Documentation/devicetree/bindings/hwlock/hwlock.txt"
-
-Example of hwlock provider:
-	hwspinlock@40500000 {
-		compatible  = "sprd,hwspinlock-r3p0";
-		reg = <0 0x40500000 0 0x1000>;
-		#hwlock-cells = <1>;
-		clock-names = "enable";
-		clocks = <&clk_aon_apb_gates0 22>;
-	};

nit: double space here before the =

> +        reg = <0 0x40500000 0 0x1000>;

nit: if there's a respin, drop the 0s and use size/address cells of 1.
