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"
