[PATCH v2 0/7] RATP i2c and GPIO support

This series of patches implements support for i2c and GPIO operations via RATP. 

It addresses most of the comments from the first series review, except for Sascha's suggestion to implement name resolving for the i2c buses and Andrey's suggestion to prepare a new helper method to initialize the i2c_client structure. I already have a patch for the latter, but will send it for review once these have been accepted and merged, as it's really a bit orthogonal to the whole RATP logic.

Another different w.r.t. v1 apart from addressing the comments is the review is that I made the RATP i2c support depend on CONFIG_I2C and the RATP GPIO support on CONFIG_GENERIC_GPIO. That was missing, and was breaking build if RATP was selected but no i2c or GPIO support was included in the build.

Comments welcome!
