Switching back to bitbanging > solves this. Could you please investigate this timeout issue? The I2C timeouts I was having on mx28 when trying to access sgtl5000 codec, was due to the lack of codec clock. After I provided the codec clock I am able to use I2C without issues and just sent a patch for it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
