2010-09-21staging: iio: amend macros for SCAN_EL creation to add separate index attrJonathan Cameron1-3/+12
As Manuel Stahl observed, putting data into the naming of an attribute (beyond what it is for) breaks the one value per attribute rule (in spirit at least). Hence we introduce a separate _index attribute for each scan element to tell userspace the ordering in output from the buffer. This will generate a lot of sparse warnings as all drivers will have unused iio_const_attrs created. The rest of the set will clean these up. The final patch will remove the old indexing method. It is not here so as to maintain one or other interface for all devices as this set progresses.

2010-09-14staging: iio: ak8975: Add ak8975 magnetometer sensorAndrew Chew3-0/+569
This is for the Asahi Kasei AK8975 3-axis magnetometer. It resides within the magnetometer section of the IIO subsystem, and implements the raw magn_x,y,z_raw attributes, as well as magn_x,y,z_scale attributes for converting to Gauss. Changed to use the magn_x,y,z_scale attributes, and made those attributes give the scale factor to conert to Gauss. Also applied more fixes from feedback. Keeping mode as an unsigned long. I'm going to add proper power management at some point anyway, which would deprecate this attribute.
