Dear list,

Does anybody use the i2c driver for ppc405?
These drivers are not part of the standard linux kernel, I found them at
www.netroedge.com/~lm78 (lm_sensors project). (Why?)
I think there's a bug in i2c-algo-ppc405.c
The function iic_xfer (ppc405 implementation of i2c_transfer) returns
always the number of bytes read / written
of the last sub-transaction.
I think it's supposed to return the number of successfully completed
transfers instead.
Just now I can't find something in the documentation on this topic but
I'm sure I've read that somewhere...
(Other drivers like i2c-alg-pcf.c are implemented in this manner)

Perhaps I should better contact the authors... I don't know what the
usual proceeding is concerning such things.

Best Regards,
Gérard

We have not pursued it enought to get the 405 i2c driver into
kernel.org.  I guess it is time...

I am in the process of updating it to the ocp format as are other 4xx
drivers. You can send me a patch.
