    1 SPRD Hardware Spinlock Device Binding
    2 -------------------------------------
    3 
    4 Required properties :
    5 - compatible : should be "sprd,hwspinlock-r3p0".
    6 - reg : the register address of hwspinlock.
    7 - #hwlock-cells : hwlock users only use the hwlock id to represent a specific
    8         hwlock, so the number of cells should be <1> here.
    9 - clock-names : Must contain "enable".
   10 - clocks : Must contain a phandle entry for the clock in clock-names, see the
   11         common clock bindings.
   12 
   13 Please look at the generic hwlock binding for usage information for consumers,
   14 "Documentation/devicetree/bindings/hwlock/hwlock.txt"
   15 
   16 Example of hwlock provider:
   17         hwspinlock@40500000 {
   18                 compatible  = "sprd,hwspinlock-r3p0";
   19                 reg = <0 0x40500000 0 0x1000>;
   20                 #hwlock-cells = <1>;
   21                 clock-names = "enable";
   22                 clocks = <&clk_aon_apb_gates0 22>;
   23         };
