Hi,
We've recently been trying to make the SI1133 light sensor work
according to what's written in its datasheet. Unfortunately many
questions remain and the si1145.c driver seems largely different from
si1133. We believe that any code sample would be of a great help. Are
you aware of any driver, unmerged patch or other code sample for this
sensor?
Regards,

the si1133 belongs in the same family as the si1153 which has a different
register layout than the previous chips, so I think a separate driver is
needed
I do have an eval board for the si1153 and started a driver, but it's not
ready for submission (yet), the si1133 should be a lot simpler than the
si1153
regards, p.

Excellent news. I'll keep a watch for this new driver to show up.
In the meantime, we just got the sensor to respond correctly using
i2cget|set commands.
FYI, the issue we had was that the reset value of ADCCONFIGx is not 0x00
(as specified by the datasheet), but 0x0f, which selected no photodiode.
Hence, we received only noise values.
Thanks a lot and have a good day

Hello Peter,
Do you have any progress that could be shared for si1153?
Even if it's not complete I could use it to begin si1133.
Thanks,
Maxime.
