[PATCH v2 0/5] ARM: add omap3 INCOstartec board support

[Christoph Fritz]

This set of patches adds board support for an omap3 system from INCOstartec.
It's based on next-20140122.

Previously it was based on next-20140115. There, everything works as expected.

On branch git://git.linaro.org/people/ulf.hansson/clk.git linaro_clk/clk-next
which holdes all "clock DT conversion" commits, bootlog shows these abnormalities:

On next-20140122 the tps65930 (which should be compatible to twl4030) doesn't
set voltage on IO.1P8 any more which leads to a lot of external subsystem
failings like dss:

[    0.602264] omapdss_dss: probe of omapdss_dss failed with error -22
[    0.602691] omapdss CORE error: Failed to initialize DSS platform driver
[    0.603240] panel-dpi panel-dpi.0: failed to find video source 'dpi.0'

Changes compared to previous version:
 - rebased on next-20140122 from next-20140115
 - using omap36xx.dtsi instead of unsupported 1ghz omap37xx100
