[PATCH] PPC4xx: Add support for multiple I2C busses 2007-02-20T09:27:08+00:00 Stefan Roese sr@denx.de 2007-02-20T09:27:08+00:00 79b2d0bb2eae09602448f7a7cb56530d2f31e6c6 This patch adds support for multiple I2C busses on the PPC4xx platforms. Define CONFIG_I2C_MULTI_BUS in the board config file to make use of this feature. It also merges the 405 and 440 i2c header files into one common file 4xx_i2c.h. Also the 4xx i2c reset procedure is reworked since I experienced some problems with the first access on the 440SPe Katmai board. Signed-off-by: Stefan Roese <sr@denx.de>

Hello,

Attached is a patch providing support for multiple I2C buses at the
command level.  The second part of the patch includes an implementation
for the MPC834x CPU and MPC8349EMDS board.

Overview:

1. Include new 'i2c' command (based on USB implementation) using
CONFIG_I2C_CMD_TREE.

2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS.  Note that
the commands to change bus number and speed are only available under the
new 'i2c' command mentioned in the first bullet.

3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus
systems.  When CONFIG_I2C_MULTI_BUS is used, this option takes the form
of an array of bus-device pairs.  Otherwise, it is an array of uchar.

CHANGELOG:
        Added new 'i2c' master command for all I2C interaction.  This is
conditionally compiled with CONFIG_I2C_CMD_TREE.  New commands added for
setting I2C bus speed as well as changing the active bus if the board
has more than one (conditionally compiled with
CONFIG_I2C_MULTI_BUS).  Updated NOPROBE logic to handle multiple buses.
Updated README.

regards,
Ben
