ASOC driver I2C communication

[claudiocasagran]

Hello all,

I've developed a driver+codec for a custom sound card. The problem is: the driver take control of the device (The device is marked UU in i2cdetect command) and do not allow to communicate in the userspace with it via I2C. The device results to be always busy. I need to send some commands to the audio chip. Is there a way to use I2C in the userspace?

Thanks in advance.
