* ARM: dts: exynos: Add sysreg phandle to ADC nodeNaveen Krishna Chatradhi2014-11-054-4/+8
| | | | | | | | | | | | | Instead of using the ADC_PHY register base address, use sysreg phandle in ADC node to control ADC_PHY configuration register. This patch adds syscon node for Exynos3250, Exynos4x12, Exynos5250, and Exynos5420, Exynos5800.

* iio: exyno-adc: use syscon for PMU register accessNaveen Krishna Chatradhi2014-11-051-9/+21
| | | | | | | | | | | This patch updates the IIO based ADC driver to use syscon and regmap APIs to access and use PMU registers instead of remapping the PMU registers in the driver.

* staging: iio: Add notrigger mode for generic_bufferKarol Wrona2014-11-051-32/+45

* iio: iadc: Qualcomm SPMI PMIC current ADC driverIvan T. Ivanov2014-10-254-0/+656
| | | | | | | | | | | The current ADC is peripheral of Qualcomm SPMI PMIC chips. It has 16 bits resolution and register space inside PMIC accessible across SPMI bus. The driver registers itself through IIO interface. Signed-off-by: Ivan T. Ivanov <iivanov@mm-sol.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio:humidity:si7020: fix pointer to i2c clientHartmut Knaack2014-10-251-2/+2
| | | | | | | | In si7020_read_raw() the pointer to the i2c client was obtained as second level pointer, although a simple pointer is appropriate. Signed-off-by: Hartmut Knaack <knaack.h@gmx.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio:humidity:si7020: cleanup read_raw and probeHartmut Knaack2014-10-251-5/+3
| | | | | | | | | | | When reading temperature or humidity values, a shift of two bits to the right needs to be applied, and only for the humidity channel a mask of the lower 12 bits needs to be applied. This reduces code repetition. During probe, i2c_set_clientdata() was used, although its counterpart was not, so drop it.

* iio: inkern: Add of_xlate function to struct iio_infoIvan T. Ivanov2014-10-252-5/+36
| | | | | | | | | | | | | | When #iio-cells is greater than '0', the driver could provide a custom of_xlate function that reads the *args* and returns the appropriate index in registered IIO channels array. Add simple translation function, suitable for the most 1:1 mapped channels in IIO chips, and use it when driver did not provide custom implementation. Signed-off-by: Ivan T.

Website: http://www.silabs.com/products/sensors/humidity-sensors/Pages/si7013-20-21.aspx These are i2c devices which measure relative humidity and temperature and all use the same protocol. The Si7013 has an additional input with programmable linearization which is not supported because that's complicated and I didn't need it.
