I was using module parameters because it allows the parameters to be tuned at runtime. You are correct however in that they don't vary after being selected once. I can resend an updated patch series with those parameters added to the platform data if you prefer. By the way, Kwangwoo's email address no longer seems to be valid. Searching the kernel tree, there also seems to be kwangwoo.lee@xxxxxxxxxx Do you know if it is current? Thierry
