2016-07-03iio: adc: add missing of_node references to iio_devMatt Ranostay1-0/+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>
2016-06-30iio:core: timestamping clock selection supportGregor Boirie1-1/+2
Adds a new per-device sysfs attribute "current_timestamp_clock" to allow userspace to select a particular POSIX clock for buffered samples and events timestamping. Following clocks, as listed in clock_gettime(2), are supported: CLOCK_REALTIME, CLOCK_MONOTONIC, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_BOOTTIME and CLOCK_TAI.

2016-06-27iio: adc: ti-adc081c: add ACPI device ID matchingDan O'Donovan1-1/+25
Add ACPI device ID matching for TI ADC081C/ADC101C/ADC121C ADCs. Signed-off-by: Dan O'Donovan <dan@emutex.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-04-17ti-adc081c: Initial triggered buffer supportCrestez Dan Leonard1-13/+64
Using this requires software triggers like CONFIG_IIO_HRTIMER_TRIGGER. The device can be configured to do internal periodic sampling but does not offer some sort of interrupt on data ready. Interrupts can only trigger when values get out of a specific range. Signed-off-by: Crestez Dan Leonard <leonard.crestez@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-04-17ti-adc081c: Add support for adc101c and adc121cCrestez Dan Leonard1-4/+47
These chips have an almost identical interface but support a different number of value bits.

2016-02-27iio: convert to common i2c_check_functionality() return valueMatt Ranostay1-1/+1
Previously most drivers that used a i2c_check_functionality() check condition required various error codes on failure. This patchset converts to a standard of -EOPNOTSUPP Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-07-11iio: Drop owner assignment from i2c_driverKrzysztof Kozlowski1-1/+0
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-10-18iio: adc: ti-adc081c: Include linux/of.h headerSachin Kamat1-0/+1
'of_match_ptr' is defined in linux/of.h. Include it explicitly to avoid build breakage in the future. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-08-03iio: adc: ti-adc081c: Use devm_* APIsSachin Kamat1-13/+5
devm_* APIs are device managed and make code simpler. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Reviewed-by: Thierry Reding <thierry.reding@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-03-17iio:adc:ti-adc081 move to info_mask_(shared_by_type/separate)Jonathan Cameron1-2/+2
The original info_mask is going away in favour of the broken out versions. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Thierry Reding <thierry.reding@avionic-design.de>
2012-11-30iio: adc: Add Texas Instruments ADC081C021/027 supportThierry Reding1-0/+161
Add support for reading conversion results from the ADC and provide them through a single IIO channel. A proper scaling factor is also exported based on the reference voltage provided by a regulator.
