Minor OMAP DTS fixes

Quoted 31 lines · Suman Anna

Hi Tony, Benoit,

This series includes couple of minor fixes in the OMAP DTS files. The patches are based on 3.15-rc2.

The first patch fixes the only WARN_ON trace present during kernel boot on OMAP5 uEVM, and this has been present since some time now.

The last patch eliminates the following traces on AM3517 based boards.

There are a few other such traces remaining, but these are all on valid nodes.

[    0.420275] platform 480c5000.aes: Cannot lookup hwmod 'aes'

Thanks applying all three into omap-for-v3.15/fixes-v2 with patch updated with the above warnings. Next time, please include the warnings into the patch description, just leave out the time stamps.
