Subject: PCA954x I2C switch/multiplexer
Date: Sat, 23 Feb 2008 17:07:01 +0100	[thread overview]
Message-ID: <200802231707.01967.roa@libero.it> (raw)

Hello, i'm new in this list, then please excuse me for my bad english...

I read the Frank's message dated jan 31 2008 about a patch for the PCA954x i2c 
mux family support.

I patched my kernel (2.6.22) without problems, bu when i load the module 
i2c_pca954x, nothing happens....

If i turn on all the kernel i2c debug related options, in dmesg i can see 
something like:

[pca9540] registered,

but, when i launch sensors-detect, i can't see any bus other than my 
i2c-amd-756.

I'm not a programmer, but reading the code, i can see that this module hasn't 
load parameters (the same result as modinfo), then, please Frank, can you 
explain me how to make the pca954x support start?

I'm a GIGABYTE GA-7DPXDW owner, where a PCA9540 "shares" two LM-90 on the sam 
i2c bus (one for each cpu), then i will be happy to test your patch if right 
pointed.

Thanks.
