Added support for Liteon 301 Ambient light sensor. Since
LTR301 and LTR501 are register compatible(and even have same
part id), LTR501 driver has been extended to support both
devices. LTR501 is similar to LTR301 in ALS sensing, But the
only difference is, LTR501 also supports proximity sensing.
LTR501 - ALS + Proximity combo
LTR301 - ALS sensor.
Following are the data sheets for both devices:

http://optoelectronics.liteon.com/upload/download/DS86-2012-0006/S_110_LTR-501ALS-01_PrelimDS_ver1[1].pdf
One more thing. The datasheet you posted is for LTR303 not LTR301.
Which chip are you adding support for?
No. I posted link for the wrong data sheet. I will fix it once I find a
proper link.
But LTR301 is register compatible with LTR501. I have verified it once
again.
If indeed the datasheet link is correct, then although LTR303 and
LTR501 are register compatbile at
a first glance I spotted at least one difference.
The ALS Control register is not the same.
(e.g ALS Gain uses 1 bit for LTR501 and 3 bits for LTR303).
thanks,
Daniel.
