Hi Jonathan,

Thanks for reviewing!

Actually, this chip only has a hardwired ALS, meaning nothing is
exposed through the input interfaces.

Yes, I agree.

This is used for setting up the I2C_BOARD_INFO() in the board file. I
grepped linux/input and found some other drivers doing the same, but if this
is not common practice I can of course move the define to the .c-file.

I'll prepare v2 based on the rest of your comments!

Thanks!
