This device is register compatible with LTR501, with a minor difference for

We handle this difference by introducing ltr501_chip_info.
Datasheet for LTR559 is at:

Looks good to me. Let us know when you've tested it ;)
Anyhow, one comment inline. It 'think' you can end up with a device probing
succesfully with no known name...
Good point.
thanks,
Daniel.

- indio_dev->name = LTR501_DRV_NAME;
+ indio_dev->name = name;
Can name still be NULL? Needs a default value that makes sense.
indio_dev->modes = INDIO_DIRECT_MODE;
I will fix this and sync with Sathya for the LTR301 support.
thanks,
Daniel.
