* iio: adc: add missing of_node references to iio_devMatt Ranostay2016-07-031-0/+1
| | | | | | | | Adding missing indio_dev->dev.of_node references to allow iio consumers to access the device channels. Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio: adc: ad7791: claim direct mode when writing frequencyAlison Schofield2016-06-031-22/+14
| | | | | | | | | | | | | | Driver was checking for direct mode and trying to lock it, but left a gap where mode could change before the desired operation. Use iio_device_claim_direct_mode() to guarantee device stays in direct mode. Refactor function to clarify look-up followed by lock sequence.

* iio: adc: ad7791: Use devm_* APIsSachin Kamat2013-08-031-14/+5
| | | | | | | | 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>
* Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-5/+5
| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
