Merge tag 'nomadik-dt-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt
From Linus Walleij:
Device tree patches for the Nomadik machine:
- Move clock registration to the device tree
- Support probing the MTU timer from the device tree
- Register user LED and user key in the device tree
- Update defconfig to account for user LED and user key
- Move pin control mappings to the device tree
* tag 'nomadik-dt-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik:
ARM: nomadik: move the pin configuration to DT
ARM: nomadik: add led and key for S8815
ARM: nomadik: register clocksource from device tree
ARM: nomadik: convert all clocks except timer to dt
clocksource: nomadik-mtu: support of probe
