2017-08-22iio:light: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-1/+0
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-03-19iio: light: us5182d: Add OF device ID tableJavier Martinez Canillas1-0/+7
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2016-08-15iio: light: us5182d: Add missing error code assignment before testChristophe JAILLET1-1/+1
It is likely that checking the result of 'pm_runtime_set_active' is expected here. Fixes: f0e5f57d3ac2 ("iio: light: us8152d: Add power management support") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-06-30iio:core: timestamping clock selection supportGregor Boirie1-1/+1
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.

2015-12-22iio: light: us5182d: Refactor read_raw functionAdriana Reus1-77/+78
A bit of refactoring for better readability. Moved and slightly reorganized all the activity necessary for reading als and proximity into a different function. This way the switch in read raw becomes clearer and more compact. Signed-off-by: Adriana Reus <adriana.reus@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-12-22iio: light: us5182d: Add interrupt support and eventsAdriana Reus1-1/+270
Add interrupt support for proximity. Add two threshold events to signal rising and falling directions. Signed-off-by: Adriana Reus <adriana.reus@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-12-22iio: light: us5182d: Fix enable status inconcistencyAdriana Reus1-4/+12
When setting als only or proximity only modes make sure that we mark the other component as disabled. This fix is in preparation of adding event support because that will make it possible to switch between one-shot and continuous modes and not tracking these correctly may cause faulty behaviour (e.g wrongfully considering px enabled and not setting an appropriate mode in the chip).

2015-12-02iio: light: us5182d: Add property for choosing default power modeAdriana Reus1-12/+78
This chip supports two power modes. 1. "one-shot" mode - the chip activates and executes one complete conversion loop and then shuts itself down. This is the default mode chosen for raw reads. 2. "continuous" mode - the chip takes continuous measurements. Continuous mode is more expensive power-wise but may be more reliable. Add a property so that if preferred, the default power mode for raw reads can be set to continuous. Separate one-shot enabling in a separate function that will be used depending on the chosen power mode. Also create a function for powering the chip on and off.
