| 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" |
