* iio: light: add MAX30100 oximeter driver supportMatt Ranostay2015-12-121-0/+21
| | | | | | | | | | | | | MAX30100 is an heart rate and pulse oximeter sensor that works using two LEDS of different wavelengths, and detecting the light reflected back. This patchset adds support for both IR and RED LED channels which can be processed in userspace to determine heart rate and blood oxygen levels.

* Documentation: devicetree: Add property for controlling power saving mode ↵Adriana Reus2015-12-021-0/+11
| | | | | | | | | | | | | | for the us5182 als sensor Add a property to allow changing the default power-saving mode. By default, at read raw the chip will activate and provide one measurent, then it will shut itself down. However, the chip can also work in "continuous" mode which may be more reliable but is also more power consuming.

It's been in the works for a long time and it will be interesting to see what hardware support shows up now that this is available. New core features + associate cleanup. * Add generic DMA buffer infrastructure * Add a DMAengine framework based buffer Also associated minor changes. - Set the device buffer watermark based on the minimum watermark for all attached buffers rather than just the 'primary' one. - iio_buffer_init - only set the watermark default if one hasn't already been provided. This allows simple support for devices with a fixed watermark. - read only attribute for watermark on fixed watermark devices. - add explicit buffer enable/disable callbacks to allow the buffer to do more than trivial actions when it is being turned on and off. * IIO_VAL_INT support in write_raw_get_fmt function. New device support * Freescale MMA7455/7456L accelerometers * Memsic MXC6255XC accelerometer * ST lis2dh12 accelerometer * TI ADS8688 ADC * TI Palamas (twl6035/7) gpadc New driver features * mma8452 - support either of the available interrupt pins to cope with the case where board layout has lead to a particular one being connected. Staging graduation * Dummy driver - this driver acts as both an example and a test device for those with out hardware to develop userspace code against. Cleanups and minor bits and bobs. * treewide - Sort out the ordering of iio_device_register/unregister vs runtime pm function calls so that it's all nice and consistent and not race prone. - Check sscanf return values. None of the cases will actually happen as the strings are supplied internally, but best to be consistent on this. * ad7780 - switch over to the gpio descriptor interface and remove the now unused platform data which gets rid of a header entirely. * ad7793 - drop a pointless else statement. * at91_adc - Swap kmalloc_array in for a kmalloc doing the same job. * dummy - get rid of some commented out lines that snuck in during the move of the driver. * lm3533-als - Print an error message on provision of an invalid resistance. * mcp320x - Add compatible strings with vendor prefix and deprecate those with no vendor prefix. * mxs-lradc - Use BIT macro in various places rather than shifted ones. * pa12203001 - Power off the chip if the registration fails. * pulsedlight-lidar-lite - add runtime PM support. * xilinx XADC - constify an iio_buffer_setup_ops structure.

| * iio: mma8452: support either of the available interrupt pinsMartin Kepplinger2015-10-251-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is important in order for everyone to be easily able to use the driver for one of the supported accelerometer chips! Until now, the driver blindly assumed that the INT1 interrupt line is wired on a user's board. But these devices have 2 interrupt lines and can route their interrupt sources to one of them. Now, if "INT2" is found and matches i2c_client->irq, INT2 will be used. The chip's default actually is INT2, which is why probably many boards will have it wired and can make use of this. Of course, this also falls back to assuming INT1, so for existing users nothing will break. The new functionality is described in the bindings doc.

* iio: adc: vf610: Determine sampling frequencies by using minimum sample timeSanchayan Maity2015-07-201-0/+5
| | | | | | | | | | | | | | | | | | | | | The driver currently does not take into account the minimum sample time as per the Figure 6-8 Chapter 9.1.1 12-bit ADC electrical characteristics. We set a static amount of cycles instead of considering the sample time as a given value, which depends on hardware characteristics. Determine sampling frequencies by first reading the device tree property node and then calculating the required Long Sample Time Adder (LSTAdder) value, based on the ADC clock frequency and sample time value obtained from the device tree. This LSTAdder value is then used for calculating the sampling frequencies possible. In case the sample time property is not specified through the device tree, a safe default value of 1000ns is assumed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for system sleep and runtime power management. To wake up the device, the SDA line should be held low for at least 33ms while SCL is high. As this is not possible using the i2c API (and not supported by all i2c adapters), a GPIO connected to the SDA line is needed. The GPIO is named "wakeup" and can be specified in a device tree with the "wakeup-gpios" binding. If the wake-up GPIO is not given, disable power management for the device. Entering sleep requires an SMBus byte access, hence power management is also disabled if byte access is not supported by the adapter.

New drivers * CM3323 color sensor. * MS5611 pressure and temperature sensor. New functionality * mup6050 - create mux clients for devices described via ACPI. The reasoning and approach taken in this patch are complex. Basically there is no otherway of finding out what is there than by some esoteric look ups in the ACPI data. * cm3232 - PM support * itg3200 - suspend/resume support * mcp320x - add more ADCs to the kconfig to reflect what the driver supports (this patch and the bindings got left behind when the support was added a while back). Docs / utils * ti-adc128s052 - DT bindings. * mcp3422 - DT bindings. * mcp320x - DT bindings * ABI docs for event threshold scale attributes, in_magn_offset, proximity scan_element and thresh falling/rising values for accelerometers. All elements long in use that have slipped by being explicitly documented. * Tidy up the tools previously in drivers/staging/iio/Documentation and move them out to /tools/iio. Yet another move that should have happened long ago. This time Roberta Dobrescu did the leg work. Thanks! Core Cleanups * Export userspace IIO headers. We should have done the appropriate header splitting a long time ago. Thanks to Daniel for sorting this out. * Refactor the registring of attributes for buffers to move all non-custom ones to a vector allowing easier additions to the current set in the future. Driver Cleanups * gpiod related cleanups. Make use of the additional parameter to specify initial direciton to avoid extra code. * bmc150 - Various refactorings to reduce code repitition and prepare for hardware buffer support. Some of these cleanups are good even without the new functionality. * kmx61 - direct use of index to an array avoiding a structure element which was always the index to an element in an array of that structure. * vf610 - avoid incorrect type for return from wait_for_completion_timeout. * gp2ap020a00f - use put_unaligned_le32 for slight code simplification. * ade7754 - improve error handling including suppressing some build warnings. * ade7759 - improve error handling including suppressing some build warnings. * hmc5843 - Long line and indentation fixes. Also some constifying of various constant data. * ade7854 - 80+ character line splitting. * ad2s1210 - fix wrong printf format string. * mxs-lradc - fix wrong printf format string. * ade7954-i2c - code alignment fixes and other trivial but worthwhile bits. * periodic rtc trigger - make the frequency type an unsigned int as it is always treated as such. * jsa1212 - constify struct regmap_config as it is constant. * ad7793 - typo in the MODULE_DESCRIPTION * mma9551 - check gpiod_to_irq errors. Note that this doesn't actually cause any trouble but is worth tidying up as obviously incorrect. * mlx90614 - refactor the register symbols to make it clear which reads are to RAM not PROM.
