[PATCHv2 0/9] Convert twl4030-madc to IIO API and add DT support

[Sebastian Reichel]

Hi,

This is PATCHv2 for converting twl4030-madc to the IIO API and
adding DT support. The plan is to remove the private twl4030-madc
API once all users have been removed or converted to the IIO API.
The patchset compiles and has been tested on my Nokia N900.

Changes since PATCHv1 [0]:
 * Fix warning about unused variable
 * Add IIO_CHAN_INFO_PROCESSED to all channels, since voltage
   channels also need some postprocessing

TODO:
 * Wait for feedback from DT binding maintainers
 * Wait for feedback from Marek Belisko, who is testing the
   changes with twl4030-madc-battery driver on GTA04
