      The OMAP hwspinlock users will use a 0-indexed relative hwlock number as
      the argument specifier value for requesting a specific hwspinlock within
      a hwspinlock bank.

      Please look at the generic hwlock binding for usage information for
      consumers, "Documentation/devicetree/bindings/hwlock/hwlock.txt"
