Hello,
Do we have a method of doing an I2C probe for OMAP I2C devices? I found
i2c_probe failing in Menelaus driver for H4-2420.
"i2c_adapter i2c-0: SMBus Quick command not supported, can't probe for
chips"
I was looking at one of the mail discussion from David B.
http://lists.lm-sensors.org/pipermail/i2c/2006-October/000298.html
I didn't see any conclusion though. Actually I don't want to do an I2C
probe, I know I2C adapter for my board. But in order to write a generic
I2C chip driver it might be required to probe for the device (as there
are multiple adapters on OMAP2430 / 3430).
Can I follow the way (using force) presented by David B in his patch?
Thanks & Regards,
Khasim

There seems to be rather more interest in a later series of patches
I posted:

The first part of that is cleanups. The second half adds a "new style"
model for driver binding, which doesn't need SMBUS_QUICK probing.
That said, I've suspected that the "controller can't do SMBUS_QUICK"
issue is something that TI should fix.
