Subject: [RFC PATCH 0/3] OMAP SSI driver

Hi !

This patchset adds an OMAP SSI driver to the HSI framework.

After leaving Nokia Carlos Chinea had no more time to work on this patchset;
Thus I tried updating the driver to fix the mentioned issues.

I applied the following changes to the last patch from Carlos:

 * convert driver to use hwmod and add SSI information to hwmod database
 * convert driver to use runtime_pm
 * change platform data, so that it forwards the wake_gpio to avoid irq_to_gpio
 * move the ssi.h and rename to hsi-omap-ssi.h (multiplatform support)

The code compiles and is initialized on the RX51. I also verified, that it
does not break the boot on my Pandaboard.

The driver has been written by Carlos Chinea and has already been sent for
public review as part of the HSI framework RFC before:
