    accessing i2c from within a device driver

    I am writing a device driver that needs access to a certain I2C controller. Is there any way of doing this generic, or should I simply write custom access routines for the I2C driver on my MCU?

    (the system is an embedded PowerPC board with a few peripherals spread over several I2C buses/controllers)

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    Have you looked at the i2c kernel code? There are certainly ways to access the controller in a more controlled fashion that reinventing the wheel, and ending up interfering with the normal operation of the i2c sub-system.
    Sometimes, real fast is almost as good as real time.
