| * iio: adc: at91: don't use the last converted data registerLudovic Desroches2014-09-141-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If touchscreen mode is enabled and a conversion is requested on another channel, the result in the last converted data register can be a touchscreen relative value. Starting a conversion involves to do a conversion for all active channel. It starts with ADC channels and ends with touchscreen channels. Then if ADC_LCD register is not read quickly, its content may be a touchscreen conversion. To remove this temporal constraint, the conversion value is taken from the channel data register.

Spec downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmi055/BST-BMI055-DS000-06.pdf The BMI055 gyroscope uses the same register definition as BMG160, but does not specify a temp register. However, the temp register seems to be working in the same way as for BMG160, so this patch does not remove the temp channel for BMI055.

Maintainer Updates * Add 3 designated reviewers for IIO. Lars, Peter and Hartmut have been actively reviewing a lot of patches for a while now so this reflects the status quo. These three are probably the only reason I keep my head above the water! New drivers and device support * max5821 DAC * Rockchip SARADC * TI ADC128S052 ADC * BMC150 Accelerometer * exynos ADC driver gains support for s3c24xx and s3c64xx parts. * kxcjk-1013 gainst range control and runtime PM support to drive down it's power usage. Driver removals * Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple basis that they drivers just provided a register write function with no compliant user space ABI whatsoever. Much better to drop them and start again for these in the fullness of time. Core Enhancements * Join together neighbouring elements in the demux units that feeds the binary interfaces. This cuts down on the number of individual copies needed when splitting out individual channels from the incoming channel scans. * Other demux related cleanups such as using roundup instead of a local implementation. Cleanups * Drop an unnecessary double setting of the owner field in xilinx adc. * Some more patches to use managed (devm) interfaces to cut down on complexity of removal code. * adis16060 coding style fixlets. * Fix some incorrect error returns in the Xilinx ADC driver. * Coding style fixlets for various accelerometer drivers. * Some sparse warning fixes to do with endianness and sign of variables. * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer in hid-sensor-magn-3d by dropping the relevant code.

| * iio: adc: exynos_adc: Add support for s3c24xx ADCChanwoo Choi2014-08-072-10/+101
| | | | | | | | | | | | | | | | | | | | | | | | This patch add support for s3c2410/s3c2416/s3c2440/s3c2443 ADC. The s3c24xx is alomost same as ADCv1. But, There are a little difference as following: - ADCMUX register address - ADCDAT mask (10 bit or 12 bit ADC resolution according to SoC version) - s3c24xx/s3c64xx has not included ADC_PHY enable register Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | The ADC in s3c64xx is almost the same as exynosv1, but has a different 'select' method. Adding this here will be helpful to move over the existing s3c64xx platform from the legacy plat-samsung/adc driver to the new exynos-adc.

| * iio: adc: add driver for Rockchip saradcHeiko Stübner2014-08-073-0/+328
| | | | | | | | | | | | | | | | | | | | The ADC is a 3-channel signal-ended 10-bit Successive Approximation Register (SAR) A/D Converter. It uses the supply and ground as its reference and converts the analog input signal into 10-bit binary digital codes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change implements BMC150 accelerometer driver. A BMC150 package consist of a compass and an accelerometer. This driver only implements accelerometer part. Spec downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-03.pdf This sensor chip supports many advanced features, but this driver implements minimum feature set which is a must to be useful. This driver can be enhanced incrementally. If the sensor vendor wants to update full featured version, they can substitute or enhance this driver when they get chance.
