Hi Mauro, this one is now based on your cx231xx branch. Regards Matthias -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Not sure if this patch is right. There is one I2C bus internally at cx231xx. Some configurations need to go through this I2C bus. Did you test if changing from/to analog/digital mode is working?

What I meant to say is that, on Colibri (e. g. cx231xx), internal I2C buses are used to control some IP parts of the chip design. Maybe setting I2C_DEMOD_EN there is a requirement for those commands to go to the right IP block. > > > Did you test if changing from/to analog/digital mode is working? > > > > I did not yet check analog mode. Ok.
