I agree with Jiaxun here - if you want the platform code to be part of mainline then the driver needs to be too. Conversely if you have drivers that are not part of the mainline kernel then maintaining the platform code to go with them should be a negligible amount of extra work. > BTW: I'm currently working on refactor Loongson32 platform with DeviceTree. Neat - I look forward to seeing that :) Thanks, Paul
