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: xilinx: Remove .owner field for driverMichal Simek2014-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to init .owner field. Based on the patch from Peter Griffin <peter.griffin@linaro.org> "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an effort to improve raw read performance and at the same time enter low power state at every possible chance. For raw reads, it will keep the system powered on for a default or user specified time, via autosuspend_delay attribute of device power. This will help read multiple samples without power on/off sequence. For triggers it will keep the system on till, requested to be turned off by trigger state by utilizing run time PM usage counters. When runtime pm is not enabled, then it keeps the chip in operation mode always.

| | * | iio: core : events ABI for specifying periodSrinivas Pandruvada2014-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iio sysfs ABI defines a way to specify period for roc and thresholds. What: /sys/.../events/in_accel_x_thresh_rising_period What: /sys/.../events/in_accel_x_thresh_falling_period what: /sys/.../events/in_accel_x_roc_rising_period What: /sys/.../events/in_accel_x_roc_falling_period But there is no way to add period with the current event info enum. Added IIO_EV_INFO_PERIOD and corresponding string. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
| | * | iio: st_sensors: add devicetree probing supportLinus Walleij2014-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C devices that make up the STMicroelectronics MEMS sensors may be sneakily enabled by cleverly giving the device node the same name as a string match from the platform device ID table. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ad7291 driver is in a reasonable shape. It does not use non-standard API/ABI and there are no major style issues with the driver. So this patch moves it out of staging. There is one small warning from checkpatch which is also fixed in this patch. The patch also sorts the #include directives in alphabetical order.

| | * | iio: st_sensors: get platform data from device treeLinus Walleij2014-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the STMicroelectronics sensors only support one single platform data item: configuration of the DRDY (data ready) pin for a particular design. Augment the core to prioritize and take this information from the device tree if the parent device has an assigned device node, else fall back to passed in platform data (usually the default data).

It also shortens and simplifies the code. This particular conversion was made more complicated by the shared library and the fact that a number of the drivers do not actually have support for setting or reading the sampling frequency. The hardware, in those cases investigated supports it. It's just never been implemented.
