    Subject[PATCHv1 0/9] Convert twl4030-madc to IIO API and add DT support
    Date
    Hi,

    This is PATCHv1 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 RFCv4 [0]:
    * Fixup all stuff found by Lee Jones and Jonathan Cameron
    in RFCv4.
    - Fixup kerneldoc comments
    - Move ARRAY_SIZE() into correct patch. I accidently rebased
    it into the wrong one.
    - Use sizeof(*madc) instead of sizeof(struct twl4030_madc_data)
    - Only call of_property_read_bool() if there is no pdata
    - I left the brackets in "reg_base + (2 * i)". They have
    been requested by Lee Jones and I think they make it easier
    to understand what is going on.
    * Add a bunch of Acked-By statements from those two
    * Add new patch, which adds *_mean_raw sysfs ABI documentation
    as requested by Jonathan Cameron
    * Add another patch, which provides iio_read_channel_average_raw(),
    so that drivers using the old API can be converted to the
    IIO API.
    * I switched from RFC to PATCH prefix.

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