Add IIO_OUT type for DAC like devices In case of IIO_OUT make sure the channel device attribute is writable Ideally we add a flag to iio_chan_spec that tells the core that the channel device attribute is writable... Signed-off-by:

New driver for AD7792/AD7793 3-Channel, Low Noise, Low Power, 16-/24-Bit Sigma-Delta ADC with On-Chip In-Amp and Reference. The AD7792/AD7793 features a dual use data out ready DOUT/RDY output. In order to avoid contentions on the SPI bus, it's necessary to use spi bus locking. The DOUT/RDY output must also be wired to an interrupt capable GPIO. In INDIO_RING_TRIGGERED mode, this driver may block its SPI bus segment for an extended period of time. Changes since V1: Use bool where applicable. Use data buffer that lives in their own cache line. Restructure ad7793_calibrate_all to use an array. Use msleep. Query REG_ID instead of doing a write/read This is a test. Add support for unipolar mode. Drop range attribute in favor of write scale. Add proper locking. Use new validate_trigger callbacks. Use IIO_IN_DIFF for differential channels. Change attribute naming. Use available_scan_masks. Some other miscellaneous cleanup (none functional changes). Signed-off-by:

Here the ordering is a little tricky, so to keep changes minimal, a copy of the gpio number is introduced. Signed-off-by:

Very simple driver, so not much to do. Signed-off-by:

I've currently squashed the vel + pos combined attribute. If people need them precisely paired I doubt they will get them from the sysfs interface anyway. If that is a requirement it should come via a buffer implementation. Note this patch leaves the completely non standard interface alone. That will get fixed later. Signed-off-by:

Note I haven't made any changes to the userspace interface as yet. This is all about cleaning up what was actually there (handling all errors etc). Signed-off-by:
