The FIMD driver expects the "vsync" interrupt to be mentioned as the 1st parameter in the FIMD DT node. So to meet this expectation of the driver, the FIMD DT node was forced to be made by keeping "vsync" as the 1st parameter.
this resolves the above mentioned "hack" by introducing "interrupt-names", so that FIMD driver can get the interrupt resource by name as discussed at http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg16211.html
patch is dependent on https://patchwork.kernel.org/patch/2184981/
