2015-10-03iio: fix drivers that use 0 as a valid IRQ in client->irq (part 2)Octavian Purdila2-2/+2
Since commit dab472eb931bc291 ("i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned") 0 is not a valid i2c client irq anymore, so change all driver's checks accordingly. The same issue occurs when the device is instantiated via device tree with no IRQ, or from the i2c sysfs interface, even before the patch above.

2015-09-23iio: mma8452: add support for MMA8652FC and MMA8653FCMartin Kepplinger2-8/+92
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.pdf Signed-off-by: Martin Kepplinger <martin.kepplinger@theobroma-systems.com> Signed-off-by: Christoph Muellner <christoph.muellner@theobroma-systems.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new device support, features and cleanup for the 4.3 cycle. Take 2 also includes a fix set that was too late for the 4.2 cycle. As we had a lot of tools and docs work in this set, I have broken those out into their own categories in this description. Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'. * Poll functions for both event chardev and the buffer one were returning negative error codes (via a positive value). * A recent change to lsiio adding some error handling that was wrong and stopped the tool working. * bmg160 was missing some dependencies in Kconfig * berlin2-adc had a misshandled register (wrote a value rather than a bitmap) New device support * TI opt3001 light sensor * TXC PA12 ALS and proximity sensor. * mcp3301 ADC support (in mcp320x driver) * ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors common support to allow different WHOAMI register addresses, devices with fixed scale and allow interrupt equiped magnetometers). * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver) * ADIS16266 gyro (in the adis16260 driver) * ADIS16137 gyro (in the adis16136 driver) New functionality * mmc35240 DT bindings. * Inverse unit conversion macros to aid handing of values written to sysfs attributes. Core cleanup * Forward declaration of struct iio_trigger to avoid a compile warning. Driver cleanup / fixes * mxs-lradc - Clarify which parts are supported. - Fix spelling erorrs. - Missing/extra includes - reorder includes - add datasheet name listings for all usable channels (to allow them to be bound by name from consumer drivers) * acpi-als - add some function prefixes as per general iio style. * bmc150_magn - replace a magic value with the existing define. * vf610 - determine possible sample frequencies taking into account the electrical characteristics (defining a minimum sample time) * dht11 - whitespace - additional docs - avoid mulitple assignments in one line - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick previously used for timing. * Fix all drivers that consider 0 a valid IRQ for historical reasons. * Export I2C module alias info where previously missing (to allow autoprobing) * Export OF module alias info where previously missing. * mmc35240 - switch some variables into arrays to improve readability. * mlx90614 - define some magic numbers for readability. * bmc150_magn - expand area locked by a mutex to cover all the use of the data->buffer. - use descriptive naming for a mask instead of a magic value. * berin2-adc - pass up an error code rather that a generic error - constify the iio_chan_spec - some other little tidy ups. * stk8312 - fix a dependency on triggered buffers in kconfig - add a check for invalid attribute values - improve error handling by returning error codes where possible and return immediately where relevant - rework macro defs to use GENMASK etc - change some variable types to reduce unnecessary casting - clean up code style - drop a local buffer copy for bulk reads and use the one in data->buffer instead. * adis16400 - the adis16448 gyroscope scale was wrong. * adis16480 - some more wrong scales for various parts. * adis16300 - has an undocumented product id and serial number registers so use them. * iio_simple_dummy - fix some wrong code indentation. * bmc150-accel - use the chip ID to detect the chip present rather than verifying the expected part was there. This was in response to a wrong ACPI entry on the WinBook TW100. * mma8452 - fix _get_hp_filter_index - drop a double include - pass up an error code rather than rewriting it - range check input values to attribute writes - register defs tidy up using GENMASK and reordering them to be easier to follow. - various coding style cleanups - put the Kconfig entry in the write place (alphabetically). Tools related * Tools cleanup - drop an explicity NULL comparison, some unnecessary braces, use the ARRAY_SIZE macro, send error messages to stderr instead of dropping them in the middle of normal output. * Fix tools to allow that scale and offset attributes are optional. * More tools fixes including allowing true 32bit data (previously an overflow prevented more than 31bits) * Drop a stray header guard that ended up in a c file. * Make calc_digits static as it isn't exported or in the header. * Set ci_array pointer to NULL after free as a protection against non safe usage of the tools core code. Also convert a double pointer to a single one as the extra level of indirection was unnecessary. Docs * DocBook introduction by Daniel Baluta. Glad we are beginning to draw together some more introductory docs to suplement the various tools / examples. * Drop bytes_per_datum sysfs attribute docs as it no longer exists. * A whole load of missing / fixing of kernel-doc for the core of IIO. * Document the trigger name sysfs attribute in the ABI docs. * Minor typos in the ABI docs related to power down modes.

2015-08-02iio: Export OF module alias information in missing driversJavier Martinez Canillas1-0/+1
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First set of IIO fixes for the 4.2 cycle. * Fix a regression in hid sensors suspend time as a result of adding runtime pm. The normal flow of waking up devices in order to go into suspend (given the devices are normally suspended when not reading) to a regression in suspend time on some laptops (reports of an additional 8 seconds). Fix this by checking to see if a user action resulting in the wake up, and make it a null operation if it didn't. Note that for hid sensors, there is nothing useful to be done when moving into a full suspend from a runtime suspend so they might as well be left alone. * rochip_saradc: fix some missing MODULE_* data including the licence so that the driver does not taint the kernel incorrectly and can build as a module. * twl4030 - mark irq as oneshot as it always should have been. * inv-mpu - write formats for attributes not specified, leading to miss interpretation of the gyro scale channel when written. * Proximity ABI clarification. This had snuck through as a mess. Some drivers thought proximity went in one direction, some the other. We went with the most common option, documented it and fixed up the drivers going the other way. Fix for sx9500 included in this set. * ad624r - fix a wrong shift in the output data. * at91_adc - remove a false limit on the value of the STARTUP register applied by too small a type for the device tree parameter. * cm3323 - clear the bits when setting the integration time (otherwise we can only ever set more bits in the relevant field). * bmc150-accel - multiple triggers are registered, but on error were not being unwound in the opposite order leading to removal of triggers that had not yet successfully been registered (count down instead of up when unwinding). * tcs3414 - ensure right part of val / val2 pair read so that the integration time is not always 0. * cc10001_adc - bug in kconfig dependency. Use of OR when AND was intended.

2015-06-14iio: accel: mma9551_core: use size in words for word buffersIrina Tirdea2-18/+18
Change the prototype for the mma9551_read/write_*_words functions to receive the length of the buffer in words (instead of bytes) since we are using a word buffer. This will prevent users from sending an odd number of bytes for a word array. Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
