I received this question from a customer. Are there any older ADAU1961 drivers based on the 3.2.x kernel?
The ADAU1961 code you have posted online seems to be based on the 3.10 or 3.12 kernel. It would be difficult for us to back port due to the new sound framework in the new kernel.
Would you happen to have a driver available for the 3.2.26 kernel that we could use, even if an earlier version?
