Subject: ARM: plat-nomadik: pass IRQ to timer driver
X-Git-Tag: v3.8-rc1~137^2~3^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0813069d03f312b48b836f20e7f12073288f0f82;p=thirdparty%2Fkernel%2Flinux.git

ARM: plat-nomadik: pass IRQ to timer driver

In order to convert the MTU timer to work with sparse IRQ we need
to pass the IRQ used when initializing instead of just letting
it rely on a special name being used in the IRQ header file.
