I will keep looking into this.
more infos
I took the current DTB file and decompiled it
I looked at the I2C sections
i2c0 = "/ocp/i2c@44e0b000";
i2c1 = "/ocp/i2c@4802a000";
i2c2 = "/ocp/i2c@4819c000";
i2c@44e0b000 {
compatible = "ti,omap4-i2c";
More infos
after reading a bit and seeing where to look I may have found the error msg.
