iio: light: tsl2563: use correct event code

2017-08-16T20:46:56+00:00

commit a3507e48d3f99a93a3056a34a5365f310434570f upstream. The TSL2563 driver provides three iio channels, two of which are raw ADC channels (channel 0 and channel 1) in the device and the remaining one is calculated by the two. The ADC channel 0 only supports programmable interrupt with threshold settings and this driver supports the event but the generated event code does not contain the corresponding iio channel type. This is going to change userspace ABI. Hopefully fixing this to be what it should always have been won't break any userspace code.

iio: light: ltr501 Fix interchanged als/ps register field

2017-05-21T13:47:39+00:00

The register mapping for the IIO driver for the Liteon Light and Proximity sensor LTR501 interrupt mode is interchanged (ALS/PS). There is a register called INTERRUPT register (address 0x8F) Bit 0 represents PS measurement trigger. Bit 1 represents ALS measurement trigger. This two bit fields are interchanged within the driver. see datasheet page 24: http://optoelectronics.liteon.com/upload/download/DS86-2012-0006/S_110_LTR-501ALS-01_PrelimDS_ver1%5B1%5D.pdf Signed-off-by: Franziska Naepelt Fixes: 7ac702b3144b6 ("iio: ltr501: Add interrupt support") Acked-by: Peter Meerwald-Stadler Cc: Signed-off-by: Jonathan Cameron

iio: light: lm3533-als: constify attribute_group structures

Check for attribute_group structures that are only stored in the event_attrs filed of iio_info structure. As the event_attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant.

iio: light: apds9960: Add OF device ID table

2017-03-19T10:55:42+00:00

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.
