Re: [PATCH] via-cuda (CUDA_COMBINED_FORMAT_IIC)

On Wed, Aug 30, 2000, Geert Uytterhoeven

The generic i2c subsystem works (at least `used to work') on PPC as well. I
once wrote an i2c `driver' (something that can read from and write to 2 signal
lines, very very complex :-)

Well, today I wish I could get at SDA/SCL - because I think I would have a
working solution to my need (to read the TDA7433).

Maybe it's complex - or at least tedious - because of working within the OS
- but it is also specified by the i2c spec - so a solvable problem.

All the time on this patch has been spent second-guessing what the CUDA does
with its command packets... and at the end I still can't read the chip (lots
of info from the SPDs & other devices ;-)

CUDA is also on m68k? (I see some conditionals in the 2.4.0 stuff for
CONFIG_MAC)

I really would be very grateful if anyone has any more sources of info on
the command packets contents for it (CUDA)...

Yeah.  AV Quadras, IIRC.  And the Q630 probably does (or at least its
descendents in the PPC line do).

Like what sort of info, and what sort of command?
