[PATCH 0/3] OMAP3 temperature sensor

I've prepared an updated variant of the omap34xx temperature monitor driver.
It's based on the N9 driver instead of the N900 driver (and thus has omap36xx

The differences compared to the original driver are:

 * DT based
 * No includes from arch, instead uses syscon DT node + regmap
 * Removed support for raw temperature reading
  - I assume this was used for debugging and regmap can be used
    instead with newer kernels.
 * Introduction of managed resources where possible
 * Usage of module_platform_driver() macro
 * Added some comments referencing the TRM

So far the patchset is _compile-tested only_. I will test it on my N900 in
the next days.
