* iio: Add I/Q modifiersLars-Peter Clausen2015-05-233-0/+50
| | | | | | | | | | | I/Q modifiers can be used to denote signals which are represented by a in-phase and a quadrature component. The ABI documentation describes the I and Q modifiers for current and voltage channels for now as those will be the most likely users.

* iio: adc: add support for BerlinAntoine Tenart2015-05-233-0/+386
| | | | | | | | | | | | | This patch adds the support of the Berlin ADC, available on Berlin SoCs. This ADC has 8 channels available, with one connected to a temperature sensor. The particularity here, is that the temperature sensor connected to the ADC has its own registers, and both the ADC and the temperature sensor must be configured when using it.

* iio: accel: bmc150: decouple buffer and triggersVlad Dogaru2015-05-171-20/+35
| | | | | | | | | | | | | | | | If the interrupt pins are not available, we should still be able to use the buffer with an external trigger. However, we won't be able to use the hardware fifo since we have no means of signalling when the watermark is reached. I also added a comment to indicate that the timestamps in bmc150_accel_data are only used for hardware fifo, since initially I was confused about duplication with pf->timestamp.

* iio: mma8452: Initialise before activatingMartin Fuzzey2015-05-171-4/+33
| | | | | | | | | | | | | | Many of the hardware configuration registers may only be modified while the device is inactive. Currently the probe code first activates the device and then modifies the registers (eg to set the scale). This doesn't actually work but is not noticed since the scale used is the default value. While at it also issue a hardware reset command at probe time. Signed-off-by: Martin Fuzzey <mfuzzey@parkeon.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

The reported timestamps may be slightly different, but the advantage is that we no longer assume that the buffer of bmg160 is triggered by its own trigger.

* iio: __iio_update_buffers: Perform request_update() only for new buffersLars-Peter Clausen2015-05-171-11/+25
| | | | | | | | | | | | | | We only have to call the request_update() callback for a newly inserted buffer. The configuration of the already previously active buffers will not have changed. This also allows us to move the request_update() call to the beginning of __iio_update_buffers(), before any currently active buffers are stopped. This makes the error handling a lot easier since no changes were made to the buffer list and no rollback needs to be performed.

* iio: __iio_update_buffers: Slightly refactor scan mask memory managementLars-Peter Clausen2015-05-171-10/+13
| | | | | | | | | | | | | | Add a small helper function iio_free_scan_mask() that takes a mask and frees its memory if the scan masks for the device are dynamically allocated, otherwise does nothing. This means we don't have to open-code the same check over and over again in __iio_update_buffers. Also free compound_mask as soon a we are done using it. This constrains its usage to a specific region of the function will make further refactoring and splitting the function into smaller sub-parts more easier.

* iio: Replace printk in __iio_update_buffers with dev_dbgLars-Peter Clausen2015-05-171-5/+7
| | | | | | | | | | | | | | | | While more verbose error messages are useful for debugging we should really not put those error messages into the kernel log for normal errors that are already reported to the application via the error code, when running in non-debug mode. Otherwise application authors might expect that this is part of the ABI and to get the error they should scan the kernel log. Which would be rather error prone itself since there is no direct mapping between a operation and the error message so it is impossible to find out which error message belongs to which error.

Sensors complying with the standard are exposed as ACPI devices with ACPI0008 as hardware ID and provide standard methods by which the OS can query properties of the ambient light environment the system is currently operating in. This driver currently allows only to get the current ambient light illuminance reading through the _ALI method, but is ready to be extended extended to handle _ALC, _ALT and _ALP as well.

New functionality * IIO_CHAN_INFO_CALIBEMISSIVITY for thermopile sensors. * kxcjk1013 - make driver operational with external trigger. * Add iio targets to the tools Makefile. Cleanups * st sensors - more helpful error message if device id wrong or irq request fails, explicitly make the Block Data Update optional rather than relying on writes to address 0 not doing anything, make interrupt support optional (Not always wired, and not all devices actually have an interrupt line.) * kxcjk-1013 white space additions for readability, add the KXCJ9000 ACPI id as seen in the wild. * sx9500 - GPIO reset support, refactor the GPIO interrupt code, add power management, optimize power usage by powering down when possible, rename the gpio interrupt pin to be more useful, trivial return path simplification, trivial formatting fixes. * isl29018 - move towards ABI compliance with a view to moving this driver out of staging, add some brackets to ensure code works as expected. Note there is no actual bug as the condition being tested is always true (with current devices). * ltr501 - add regmap support to get caching etc for later patches, fix a parameter sanity check that always fails (bug introduced earlier in this series), ACPI enumeration support, interrupt rate control support, interrupt support in general and integration time control support, code alignment cleanups. * mma9553 - a number of little cleanups following a review from Hartmut after I'd already applied the original driver patch. * tmp006 - prefix some defines with TMP006 for consistency. * tsl4531 - cleanup some wrong prefixes, presumably from copy and paste. * mlx90614 - check for errors in read values, add power management, add emissivity setting, add device tree binding documentation, fix a duplicate const warning. * ti_am335x_adc - refactor the DT parsing into a separate function.
