[PATCH v2 0/5] OMAP: Add DT bindings to specify when devices should not be idled or reset

[Rajendra Nayak]

Changes in v2:
* Patches are split in such a way that DT and hwmod changes are kept in
seperate patches so they can be pulled in by Benoit and Paul seperately.
* Binding names are slightly updated to address the concern from Tony and Benoit [1]
* Added a patch [5/5] to prevent GPIO reset on AM335x EVM-SK board, which
was also the original motivation of this series since the board fails to
boot from mainline despite support for AM335x and a am335x-evmsk.dts file
existing in mainline for quite a while.

We have devices like co-processors, SoC internal busses, memory controllers
etc which should not be idled or reset. In some cases erratas around IP blocks
prevent them from either being idled or reset. Have a way to pass this
information from Device tree, and get rid of similar information that
exists as part of the omap_hwmod data files for various DT only OMAP SoCs.

Boot tested on OMAP4 panda es, AM335x EVM and AM335x EVM-SK
