Merge tag 'mtu-clk-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/multiplatform
From Linus Walleij <linus.walleij@linaro.org>:
This tag contains two MTU patches based on top of the ux500 sparse IRQ
commit to avoid merge clashes.
* tag 'mtu-clk-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
clocksource/mtu-nomadik: use apb_pclk
clk: ux500: Register mtu apb_pclocks
