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
