Enhance interrupt generation in the dummy driver and expand its usage by introducing the irq_work infrastructure to trigger an interrupt. This way, the irq_work_queue() wrapper permits calling both of the top half and threaded part from a hard irq context, unlike handle_nested_irq(), which only calls the threaded part. As an outcome, the driver succeeds in simulating real hardware interrupts, while keeping the normal interrupt flow. Signed-off-by:

There are air quality sensors that report data back in parts per million of VOC (Volatile Organic Compounds) which are usually indexed from CO2 or another common pollutant. This patchset adds an IIO_CONCENTRATION type that returns a percentage of substance because no other channels types fit this use case. Modifiers for IIO_MOD_CO2 and IIO_MOD_VOC gas types are defined.

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by:

This doesn't actually change anything since the core names the sysfs folder for the iio event attributes "events" anyways. It only leaves the job to the core. Signed-off-by:

MMA8652FC and MMA8653FC don't provide the transient interrupt source, so the motion interrupt source is used by providing a new iio_chan_spec definition, so that other supported devices are not affected by this. Datasheets for the newly supported devices are available at Freescale's website: http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8652FC.pdf http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8653FC.pdfSigned-off-by:

This adds support for the 10 bit version if Freescale's accelerometers of this series. The datasheet is available at Freescale's website: http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8453Q.pdf It creates a devicetree bindings file to document the new functionality and removes the driver from the trivial-devices list.

This adds a struct mma_chip_info to hold data that will remain specific to the chip in use. It is provided during probe() and linked in struct of_device_id. Also this suggests that the driver is called "mma8452" and now handles the MMA8452Q device, but is not limited to it. Signed-off-by:

The tsl4531_check_id() function returned 1 on "found" and 0 on "not found" and negative error codes on failure. This was non-standard and bug prone. The caller treated all non-zero values including error codes as "found". This patch fixes it by changing the tsl4531_check_id() to return zero on success or a negative error code, and updates the caller. Signed-off-by:

Implemented Low pass 3db frequency filter which configures FIR and IIR values within the configuration register of EEPROM. For more standardized interface we have fixed the FIR value to 1024, while changes in IIR value are directly connected to filter responses. The new datasheet version will provide a simplified table (also in reStructured text format below) with this change, to provide quick overview of possible settings. Below sensor timings (bandwidth) are calculated for 3db frequency low pass filter. +--------------------+-----------------+ | Filter setting (%) | Band width (Hz) | | (rounded to 1.0) | | +====================+=================+ | 13 | 0.15 | +--------------------+-----------------+ | 17 | 0.20 | +--------------------+-----------------+ | 25 | 0.31 | +--------------------+-----------------+ | 50 | 0.77 | +--------------------+-----------------+ | 57 | 0.86 | +--------------------+-----------------+ | 67 | 1.10 | +--------------------+-----------------+ | 80 | 1.53 | +--------------------+-----------------+ | 100 | 7.23 | +--------------------+-----------------+ The diff is made towards togreg branch.

The maximum possible value for the relative humidity is 55575 (100%RH). This value, if shifted right by 2 bits, uses 14 bits and masking it with a 12 bit mask removes 2 meaningful bits. The masking has been replaced with a range check that sets the minimum value at 786 (0%RH) and the maximum at 13893 (99.998%RH). Signed-off-by:

The SPI core always reports the MODALIAS uevent as "spi:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: SPI id table or OF match table). So drivers needs to export the SPI id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added.
