[PATCHv4 0/7] Convert twl4030-madc to IIO API and add DT support

[Sebastian Reichel <sre-8fiUuRrzOP0dnm+yROfE0A@public.gmane.org>]

Hi,

This is PATCHv4 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 PATCHv3 [0]:
 * Dropped the following patches (applied in iio tree)
  - iio: documentation: Add ABI documentation for *_mean_raw
  - iio: inkern: add iio_read_channel_average_raw
 * Added some more Acked-by from Jonathan Cameron
  - one of them on the basis of "Reorder that and I'm happy".
 * Changed some minor stuff requested by Jonathan
  - reorder cleanup calls in driver's remove function
  - convert another comment to kerneldoc

Status:
 * Only feedback from DT binding maintainers is missing.
   side note: The binding & the corresponding binding documentation
   patch has not changed since 2014-02-13. So depending on when the
   time frame starts the three weeks are over already ;)
 * It would be nice to see this patchset in 3.15.
