Jonathan writes: First round of new drivers, features and cleanups for IIO in the 3.19 cycle. New drivers / supported parts * rockchip - rk3066-tsadc variant * si7020 humidity and temperature sensor * mcp320x - add mcp3001, mcp3002, mcp3004, mcp3008, mcp3201, mcp3202 * bmp280 pressure and temperature sensor * Qualcomm SPMI PMIC current ADC driver * Exynos_adc - support exynos7 New features * vf610-adc - add temperature sensor support * Documentation of current attributes, scaled pressure, offset and scaled humidity, RGBC intensity gain factor and scale applied to differential voltage channels. * Bring iio_event_monitor up to date with newer modifiers. * Add of_xlate function to allow for complex channel mappings from the device tree. * Add -g parameter to generic_buffer example to allow for devices with directly fed (no trigger) buffers. * Move exynos driver over to syscon for PMU register access. Cleanups, fixes for new drivers * lis3l02dq drop an unneeded else. * st sensors - renam st_sensors to st_sensor_settings (for clarity) * st sensors - drop an unused parameter from all the probe utility functions. * vf610 better error handling and tidy up. * si7020 - cleanups following merge * as3935 - drop some unnecessary semicolons. * bmp280 - fix the pressure calculation.
2014-11-05staging: iio: Add notrigger mode for generic_bufferKarol Wrona1-32/+45
Some IIO devices do not use the triggers. This patch makes trigger setting conditional so generic_buffer can be used when triggers are disabled. Signed-off-by: Karol Wrona <k.wrona@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
