2017-08-22	iio:light: drop assign iio_info.driver_module and iio_trigger_ops.owner	Jonathan Cameron	1	-1/+0
	The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2016-12-04	iio: light: fix improper return value	Pan Bian	1	-1/+1
	In function cm3232_reg_init(), it returns 0 even if the last call to i2c_smbus_write_byte_data() returns a negative value (indicates error). As a result, the return value may be inconsistent with the execution status, and the caller of cm3232_reg_init() will not be able to detect the error. This patch fixes the bug.

2015-08-02	iio: Export OF module alias information in missing drivers	Javier Martinez Canillas	1	-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.

2015-07-11	iio: Drop owner assignment from i2c_driver	Krzysztof Kozlowski	1	-1/+0
	i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-03-08	iio: light: Added PM support for Capella CM3232 ambient light sensor driver.	Kevin Tsai	1	-0/+36

2015-01-27	iio: Added Capella cm3232 ambient light sensor driver.	Kevin Tsai	1	-0/+403
	CM3232 is an advanced ambient light sensor with I2C protocol interface. The I2C slave address is internally hardwired as 0x10 (7-bit). Writing to configure register is byte mode, but reading ALS register requests to use word mode for 16-bit resolution.
