2016-03-09iio: adc/imx25-gcq: Move incorrect do_divArnd Bergmann
The newly added driver uses do_div() to device a 32-bit number, which now provokes a warning: drivers/iio/adc/fsl-imx25-gcq.c: In function 'mx25_gcq_setup_cfgs': include/asm-generic/div64.h:207:28: warning: comparison of distinct pointer types lacks a cast (void)(((typeof((n)) *)0) == ((uint64_t *)0)); \ This replaces the do_div() call with a straight division operator.

New Device Support * Apex stx104 DAC - new driver for this PC104 board. Right now DAC support only. * ADI ad5064 - Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs. - Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616, ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629. * ADI ad7192 - add support for the ad7193 * Invensense mpu6050 - substantial rework of driver to use regmap allowing SPI support extending the now split driver to cover the MPU6000. * TI adc0832 - new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs. * TI ads1015 - new driver, note that there is an existing hwmon driver. The long term intention is to probably remove the hwmon driver but for now we just have guards in place to ensure this driver is not built if that one is enabled. * TI afe4403 - new driver for this heart rate monitor / pulse oximeter front end chip. * TI afe4404 - new driver for this heart rate monitor / pulse oximeter front end chip. Staging Graduations * mxs-lradc - A combined general purpose and touch screen (input) device driver. Originally held in staging to allow reworking into and MFD but as that wasn't happening and isn't an absolute requirement we are moving it out of staging. Driver new features * ms5611 - triggered buffer support - IIO_CHAN_INFO_SCALE to aid the triggered buffer support. Driver cleanups / reworks / fixes * ad5064 - Use an enum for the register map layout to allow support of additional chips (precursor to the new support listed above). - Structural driver changes to allow support of the slightly different handling for the ltc parts above. * ad5933 - drop an exceptional & unnecessary for a function pointer. * ad7606 - Cleanup the repeated copies of pm ops. - consolidate the various channels specs via a sport of rearranging so only one version is needed. * atlas ph sensor - add select IRQ_WORK * hmc8543 (soon to move out of staging) - Comment style fixes - functionality of suspend and resume was swapped. * spear-adc - use devm_clk_dev instead of managing the clk lifetime by hand. Core * Use new dmaengine_terminate_sync call to avoid a theoretical race. * Fix docs for mlock in struct iio_dev as it is correctly taken in some drivers (docs used to say for core only). * Add a helper function for calculating the scan index storage size within the core cutting out some cut and paste versions of the same code.

2016-02-11iio: adc: Add imx25-gcq ADC driverMarkus Pargmann
This is a conversion queue driver for the mx25 SoC. It uses the central ADC which is used by two seperate independent queues. This driver prepares different conversion configurations for each possible input. For a conversion it creates a conversionqueue of one item with the correct configuration for the chosen channel. It then executes the queue once and disables the conversion queue afterwards. The reference voltages are configurable through devicetree subnodes, depending on the connections of the ADC inputs.

The AD5625/AD5645/AD5665 are a family of 4 channel DACs with 12-bit, 14-bit and 16-bit precision respectively. The devices come in 3 flavors in terms of built-in reference, either no built-in reference, built-in 1.25V reference or built-in 2.5V reference. The AD5627/AD5647/AD5667 are similar to the AD5625/AD5645/AD5665 except that they have 2 instead of 4 channels. While these new devices are mostly register map compatible with the existing devices support by the driver some offsets and register addresses have been shuffled around. To accommodate this introduce a new register map layout. For the lack of a better name we will just call it version 2.

2016-02-08iio:ad5064: Structural changes to support LTC2617Marc Andre
This patch makes minor structural changes to support specifics for LTC2617 DAC. This DAC requires different handling of the power down modes. The configuration to actually support the DAC will be submitted in a secondary patch. Adjust the DECLARE_AD5064_CHANNELS() macro to accept a new ext_info parameter. This allows to use different power down modes per DAC. (e.g. DAC only support 90kohm to ground) Add the chip_info parameter "powerdown_ltc". This parameter is used in the ad5064_sync_powerdown_mode() function to handle the power down command for LTC diffently. For those devices the power down command must be addressed to the channel.
