Multi-bus I2C implementation of MPC834x
Hello,
Attached is a patch implementing multiple I2C buses on the MPC834x CPU
family and the MPC8349EMDS board in particular.
This patch requires Patch 1 (Add support for multiple I2C buses).
Testing was performed on a 533MHz board.
/*** Note: This patch replaces ticket DNX#2006083042000027 ***/
Signed-off-by: Ben Warren <bwarren@qstreams.com>
CHANGELOG:
Implemented driver-level code to support two I2C buses on the
MPC834x CPU family and the MPC8349EMDS board. Available I2C bus speeds
are 50kHz, 100kHz and 400kHz on each bus.
regards,
Ben
