* iio: Export OF module alias information in missing driversJavier Martinez Canillas2015-08-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

* iio: light: cm32181: Use devm_* APIsBeomho Seo2014-06-211-10/+1
| | | | | | | | This patch changes API from iio_device_register() to devm_* API. Using API make code simpler. Signed-off-by: Beomho Seo <beomho.seo@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* iio: cm32181: Fix read integration time functionBeomho Seo2014-03-151-0/+1
| | | | | | | | | In read integration time function, assign 0 to val. Because, prevent return inaccurate value when call read integration time.

* iio: cm32181: Change cm32181 ambient light sensor driverBeomho Seo2014-02-181-8/+8
| | | | | | | | | | | | | Integration time of cm32181 is guessed about milliseconds. But cm32181_read_als_it function return IIO_VAL_INT. So fixed to return IIO_VAL_INT_PLUS_MICRO. Next, add .write_raw_get_fmt callback function for call iio_str_to_fixpoint. v2: cm32181_write_als_id function fixed as it was.
