Hi Peter, I just studied the ltr501 driver for reference and found the following: 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. see datesheet: http://optoelectronics.liteon.com/upload/download/DS86-2012-0006/S_110_LTR-501ALS-01_PrelimDS_ver1%5B1%5D.pdf - page 24 This two bit fields are interchanged within the driver: drivers/iio/light/ltr501.c. I just refer to the datasheet because I don't have such kind of sensor to test it. The datasheet of the LTR559 which is covered by this driver as well has the same register mapping like LTR501.
