[PATCH] ARM: dts: add interrupt-names property to get interrupt resource by name

[Vikas Sajjan <vikas.sajjan@linaro.org>]

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/
