This is to be used by some magnetometers that provide data in this way. * hid magnetometer now supports output rotations from various variants on North * HMC5843 driver converted to regmap and reworked to allow easy support of other similar devices. Support for HMC5983 added via both i2c and SPI. * Rework of Exynos driver to simplify extension to support more devices. * Addition of support for the Exynos3250 ADC (which requires an additional clock) Support for quite a few more devices on its way. Cleanups * ad7997 - a number of cleanups and tweaks to how the events are controlled to make it more intuitive. * kxcjk - cleanups and minor fixes for this new driver.

If special clock of ADC is registerd on clock list of common clk framework, Exynos ADC drvier have to control this clock. Exynos3250/Exynos4/Exynos5 has 'adc' clock as following: - 'adc' clock: bus clock for ADC Exynos3250 has additional 'sclk_adc' clock as following: - 'sclk_adc' clock: special clock for ADC which provide clock to internal ADC Exynos 4210/4212/4412 and Exynos5250/5420 has not included 'sclk_adc' clock in FSYS_BLK. But, Exynos3250 based on Cortex-A7 has only included 'sclk_adc' clock in FSYS_BLK.

It has been in the abi for a while, but not added until now to the newer handling of information related to events. * Add HAS_IOMEM dependency to mxs_lradc to avoid build issues when testing enabled.

However the right method is to use the compatible string. On detection, the ST sensors use the ID string to probe and instatiate the right sensor driver, so pass the kernel-internal ID string in the .data field of the OF match table, and set the I2C client name to this name when a compatible match is used. This avoids having misc Linux-specific strings floating around in the device tree.

New drivers * mcp4902, mcp4912 and mcp4922 SPI DAC driver. * max1027, max1029 and max1031 SPI ADC driver. Cleanups * cm32181 - use devm APIs to simplify error paths. * ak8975 - use devm APIs to simplify error paths. * ad9850 - drop some unused defines and an unnecessary goto. * hmc5843 - add missing devices to the device id table and the documentation. * ad9832 - small formatting cleanups. * sca3000 - hide direct use of the stufftoread element by adding a data_available function. This is a precursor for the addition of buffer watermarks to the subsystem but stands as a good cleanup on its own.
