good

10:40 < khali> Driver smsc47m1 always use i2c-isa driver.
10:40 < khali> it's not the same part of the device being accessed
10:41 < khali> throught ISA we have fan monitoring and control
10:41 < khali> on SMBus we have temperature and voltage monitoring

10:39 < khali> and a driver is supposed to be in progress, but it's a long time
               we didn't hear about it

Thomas,
Any news?


Last test the BUS transport will be the byte write mode.

i2cdump 0 0x2d

Should give you a register dump.

Datasheet is here
http://www.smsc.com/main/tools/discontinued/47m15x.pdf

Now please read the value on offset 0x31 (5V high limit) and add one to it and write it back to chip

i2cset 0 0x2d 0x31 0xyourvall

Readback should match.

Thanks

Regards
Rudolf
