MPC107 I2C

MPC107 I2C

[Adrian Cox]

Does anybody know of an I2C driver for the MPC107?  The only clue I
found on Google (searching for "MPC107 linux i2c") was a post by Dan
Malek saying "I believe the code is lurking around somewhere".

I wrote that :-)?  Must have been one of my more foggy days.  Any time
a question like that is asked I scan the archives looking for tidbits of
information.  I must have found someone that posted something about it.

I believe there is (was, it's harder to find these days without registration)
software on Motorla's website to do this.  I tend to avoid sites that
require a) registration and, b) Internet Exploder to work properly, so I
don't know what is on their website these days.

Apparently so:

I'll take a look. I find Motorola's website a complete pain to navigate,
so I try to avoid it as well. Searching for "+linux +i2c +mpc107" on
Motorola's site finds 5 documents, none of them relevant.

No linux drivers, but the moto code (for the 8240) is in the ppcboot
tree these days, and I know that gbios has enough of i2c up to read
SODIMMs.

Did my question about EUMBBAR and the 8245's serial port(s) not make
it out to the list?

Thanks.

Yes, and you can _pay_ me for 30 second responses to e-mail :-).  If
you want free help you need to wait until someone is free to respond.

Thanks.

I suspected as much. I wrote the GBIOS code, which does DIMM reading and
also can store environment variables in I2C eeproms. If there's no
driver out there I'll need to convert the code from polling to
interrupts and fit it into the Linux i2c framework.

OK, but thats now how I meant it.  I hadn't seen my email come back
from either list.

I guess I didn't use enough of these :-) :-).

I have noticed that sometimes my messages take a long time to appear
and other times they are almost instant, so I kind of understand your
asking.

Have a good one.
