I can merge my version of the driver with your and get a final driver, indeed your i2c is much better, as I coded i2c as a i2c ignorant, so just copying from the other drivers. I will just take your implementation for that part. Thanks a lot for the i2c explanation, that explains! Now my view is much clearer. So what if I try to merge the two drivers to get a clean one, test them on pctv60e, you test them on pctv200e and... done! The cherry would be to spend some time on the IR also, but just wait to have a driver.
