This driver supports:
- reading channels in 'one shot' mode through read_raw callback,
- four events - rising and falling ambient light events and
rising and falling proximity roc events.
- triggers for all the three channels (triggers can't be enabled
simultaneosly with proximity detection event)
This is a follow-up of the previous patch and it includes
following improvements (Jonathan and Peter - thanks for the review):
- changed "Opto" to "ALS" in the driver description
- switched from HZ to jiffies units for the GP2AP020A00F_DATA_READY_TIMEOUT
- added proximity detection falling event
- added lookup table of register settings for different opmodes
- switched to using regmap
- added debugfs reg_addr and reg_val attributes
- switched to using proximity detection/non detection device
functionality for the proximity events (single event is generated
upon crossing high and low thresholds)
- adjusting lux mode depending on the light clear output value
Issues:
- WARNING: at kernel/irq/handle.c:146 on call to iio_trigger_poll
- how to deal with the scale value that changes depending on the output
value?
Thanks,
Jacek
