Dear Heiko Schocher,
In message 48E089F8.1070809@denx.de you wrote:
As Documented in README, adding a boardspecific Deblocking
Which part of the README are you referring to?
mechansim via CFG_I2C_INIT_BOARD for the mgcoge and mgsuvd board.
Are you talking about doc/I2C_Edge_Conditions?
This code was originally written by keymile in association with Anatech and Atmel in 1998. The Code toggels the SCL until the SCA line goes to High (max. 16 times). And after this, a start Condition is send.

Hm... quoting doc/I2C_Edge_Conditions:
... Note that this is NOT necessary when using the bit-banging I2C driver (common/soft_i2c.c) as this already includes the I2C bus reset sequence.
Can you please explain what your patch is doing differently, and why it is needed?
Best regards,
Wolfgang Denk
