One thing I'm concerned about is switching the DCLK registers to DCC mode without any protection against mode changes co-inciding with I2C activity. On a SMP machine, it's possible for both to happen simultaneously. Secondly, please name these I2C bits with 'ddc' in the name - the CyberPro appear to have more than one I2C bus on them (or can have) such as for driving SAA7111 video decoders. -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
