2014-02-18iio: cm36651: Fix read/write integration time function.Beomho Seo
This patch is fixed [read/write] integration time function. cm36651 have integration time from 1 to 640 milliseconds. But, print more then the thousand second. when call *_integration_time attribute. Because read_integration_time function return IIO_VAL_INT. read integration time function is changed return IIO_VAL_INT_PLUS_MICRO; And then .write_raw_get_fmt callback function for parse a fixed-point number from a string. Some description is revised milliseconds unit. v2: cm36651_write_int_time function fixed as it was.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 2nd round of new IIO drivers, features and cleanups for the 3.14 cycle. New drivers * HID inclinometer driver. * DHT11 humidity driver. Note that previous humidity drivers have been in hwmon, but no one was ever entirely happy with that, and they should find a more comfortable home in IIO (their original placement in hwmon was my fault - oops). As this is our first humidity driver, core support is also added. New features * Two of mxs-lradc channels are internally wired to a temperature sensor, make this explicit in the driver by providing the relevant temperature channel. * Add support for blocking IO on buffers. * Add a data_available call back to the interface between buffer implementations and the core. This is much cleaner than the old, 'stufftoread' flag. Implemented in the kfifo buffer. Cleanups * Last user of the old event configuration interface is converted and the old interface dropped. Nice to be rid of this thanks to Lars-Peter's hard work! * Replace all remaining instances of the IIO_ST macro with explicit filling of the scan_type structure within struct iio_chan_spec. This macro was a bad idea, that rapidly ceased to cover all elements of the structure. Miss reading of the macro arguements has led to a number of bugs so lets just get rid of it. The final removal patch is awaiting for some fixes to make their way into mainline. In a couple of drivers, no elements of scan_type were even being used so in those case, it has been dropped entirely. * Drop a couple of of_match_ptr helper uses in drivers where devicetree is not optional and hence the structures being protected by this always exist. * Fix up some cases where data was read from a device in a particular byte order, but he code placed it into a s16 or similar. These were highlighted by Sparse. * Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers core code. * ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code and possibly avoiding issues with i2c bus drivers that assume they can dma directly into the buffer. Note that this cannot currently happen as the the i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually passed to the bus driver. I missed this element of the commit message and don't think it is major enough to rebase the iio tree. * ad5791 and ad5504 stop storing buffers on the stack for an SPI driver. Unlike the i2c drivers, this is a real issue for SPI drivers which can dma directly into the buffer supplied.

'cm36651_of_match' is always compiled in. Hence the helper macro is not needed. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-12-15iio: cm36651: Changed return value of read functionBeomho Seo
A return value of callback have been changed to IIO_VAL_INT. If not IIO_VAL_INT, driver will print wrong value(*_read_int_time). A follow up patch will deal with a related bug in the new event handling code. Signed-off-by: Beomho Seo <beomho.seo@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-12-08iio: Remove support for the legacy event config interfaceLars-Peter Clausen
Now that all drivers have been converted to the new event config interface we can remove for the legacy event config interface. Also drop the '_new' suffix for the event config interface callbacks, since those are the only callbacks now.
