No - that would be a regression .. but read on > Magnetometers act as ADCs and can have high sampling rates and > complex internals, so I think that according to > drivers/staging/iio/Documentation/overview.txt they should almost always > land in IIO land. IIO is a staging project that may never go anywhere - some of us are using magnetometers in product so this alone isn't an answer that works right now. > I would be willing to work on the change as I want to submit a similar > driver for the HMC6343 magnetometer/accelerometer as well. It would be great if it got added into the IIO subystem *as well*, and in time when and if IIO goes out of staging it would then eventually replace the existing drivers. Alan
