Merge tag 'vt8500-for-next' of git://git.code.sf.net/p/linuxwmt/code into next/dt
From Tony Prisk:
Update arch-vt8500 and drivers to device tree and
remove existing non-dt code.
* tag 'vt8500-for-next' of git://git.code.sf.net/p/linuxwmt/code:
arm: vt8500: Update arch-vt8500 to devicetree support.
arm: vt8500: gpio: Devicetree support for arch-vt8500
arm: vt8500: doc: Add device tree bindings for arch-vt8500 devices
arm: vt8500: clk: Add Common Clock Framework support
video: vt8500: Add devicetree support for vt8500-fb and wm8505-fb
serial: vt8500: Add devicetree support for vt8500-serial
rtc: vt8500: Add devicetree support for vt8500-rtc
arm: vt8500: Add device tree files for VIA/Wondermedia SoC's
Resolved add/change conflict in drivers/clk/Makefile.
