* iio:ad7923: Use iio_push_to_buffers_with_timestamp()Lars-Peter Clausen2013-09-211-8/+2
| | | | | | | Makes the code a bit shorter and less ugly. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio: Remove unnecessary casts for iio_push_to_buffers()Lars-Peter Clausen2013-09-151-1/+1
| | | | | | | | Now that iio_push_to_buffers() takes a void pointer for the data parameter we can remove those casts to u8*. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio: adc: ad7923: Use devm_* APIsSachin Kamat2013-08-031-13/+7
| | | | | | | | devm_* APIs are device managed and make code simpler. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio:adc:ad7923: Add support for the ad7904/ad7914/ad7924Lars-Peter Clausen2013-03-171-13/+50
| | | | | | | | | | | | | The ad7924 is software compatible with the ad7923. The ad7904 and ad7914 are the 8 and 10 bit version of the ad7924. While we are at it also drop the "with temperature sensor" from the Kconfig entry, since the chips do not have a temperature sensor.

* iio:ad7923: Implement scale reportingLars-Peter Clausen2013-03-171-7/+53
| | | | | | | | | | | | | | | The driver already claims to support scale reporting in its channel spec, but doesn't actually implement this yet. This patch uses the regulator API to get the reference voltage and calculates the scale based on that. The patch also moves the global configuration bits into a field in the ad7923_state struct, since depending on the RANGE bit, the range goes either from 0 to VREF or from 0 to 2 * VREF. So we need to know the setting of the RANGE bit when calculating the scale.

* iio:ad7923: Return error if we didn't get the expected resultLars-Peter Clausen2013-03-171-0/+2
| | | | | | | | | | Instead of leaving 'val' uninitialized return an error if the result's address did not match that of the channel we were trying to read.
