2015-05-02Documentation: dt: add common bindings for hwspinlockSuman Anna
This patch adds the generic common bindings used to represent a hwlock device and use/request locks in a device-tree build. Each hwspinlock provider should have the '#hwlock-cells' property, which represents the number of cells to be used for representing a specific hwspinlock. Client users shall use the property 'hwlocks' for requesting specific lock(s). Note that the document is named hwlock.txt deliberately to keep it a bit more generic.
