Device Driver for lm75 on 8260

Device Driver for lm75 on 8260

[barry.fisher]

 Hello All!
 Does anyone know where I can get some code(or sample code) for a Linux
 device driver on an 8260 which gets temperature data from an lm75 via
 i2c. Any help is appreciated! Thanks in advance.

We have generic I2C support for the 8260 (drivers/i2c/i2c-algo-8260.c)
in our version of the Linux kernel, and drivers for instance for  the
MicroSys PM826 ("Miriac") module, too (drivers/i2c/i2c-pm826.c).

See ftp://ftp.denx.de/pub/LinuxPPC/usr/src/linux-2.4.4-2002-01-19.tar.bz2

Reading the LM sensor is then just a minor excercise..
