I do agree that we need move to use the chipidea driver and eventually remove the fsl udc driver, but there were many users of the current driver such as PowerPC and Coldfire platforms besides the i.MX platforms. The support for them with chipidea driver could also be broken for now. I would suggest to have a transitional period that both drivers are kept while new development be based on the new driver.
Added Ramneek. What do you think of the current status for chipidea driver on PowerPC platforms?
