iio: trigger: implement devm_iio_trigger_alloc/devm_iio_triger_free

2013-08-17T18:34:52Z

Add a resource managed devm_iio_trigger_alloc()/devm_iio_triger_free() to automatically clean up triggers allocated by IIO drivers, thus leading to simplified IIO drivers code. Signed-off-by: Jacek Anaszewski Signed-off-by: Kyunmin Park Signed-off-by: Jonathan Cameron

iio: core: implement devm_iio_device_alloc/devm_iio_device_free

2013-08-03T17:40:37Z

Add a resource managed devm_iio_device_alloc()/devm_iio_device_free() to automatically clean up any allocations made by IIO drivers, thus leading to simplified IIO drivers code. In addition, this will allow IIO drivers to use other devm_*() API (like devm_request_irq) and don't care about the race between iio_device_free() and the release of resources by Device core during driver removing.

iio: Remove IIO_DEV_ATTR_RESET macro

2013-08-03T17:40:37Z

There are no users of this macro left and we have come to the conclusion that it is not a good idea to expose the raw chip reset to userspace so the macro is very unlikely to be used in new drivers. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron

iio: Added ST-sensors platform data to select the DRDY interrupt pin

2013-08-03T17:40:28Z

This patch add support to redirect the DRDY interrupt on INT1 or INT2 on accelerometer and pressure sensors. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio:trigger: Fix use_count race condition

2013-07-20T09:18:53Z

When using more than one trigger consumer it can happen that multiple threads perform a read-modify-update cycle on 'use_count' concurrently. This can cause updates to be lost and use_count can get stuck at non-zero value, in which case the IIO core assumes that at least one thread is still running and will wait for it to finish before running any trigger handlers again. This effectively renders the trigger disabled and a reboot is necessary before it can be used again. To fix this make use_count an atomic variable. Also set it to the number of consumers before starting the first consumer, otherwise it might happen that use_count drops to 0 even though not all consumers have been run yet.

iio: Fix iio_channel_has_info

2013-07-02T21:08:20Z

Since the info_mask split, iio_channel_has_info() is not working correctly. info_mask_separate and info_mask_shared_by_type, it is not possible to compare them directly with the iio_chan_info_enum enum. Correct that bit using the BIT() macro. Cc: # 3.10.x Signed-off-by: Alexandre Belloni Signed-off-by: Jonathan Cameron

iio:common: Removed stuff macros, added num_data_channels on st_sensors struct and added support on one-shot sysfs reads to 3 byte channel

2013-06-05T17:41:23Z

This patch introduce num_data_channels variable on st_sensors struct to manage different type of channels (size or number) in st_sensors_get_buffer_element function. Removed ST_SENSORS_NUMBER_DATA_CHANNELS and ST_SENSORS_BYTE_FOR_CHANNEL and used struct iio_chan_spec const *ch to catch data. Added 3 byte channel data support on one-shot reads.
