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" |
