While the ths7353 is pretty complete it needs some tidying up and the ths8200 still needs more work. I don't have time to do that, but I will post our ths7353 driver so you can take the best bits of both. Ping me when you start working on the ths8200 (or anyone else who is interested in that driver) and I can mail it. Regards, Hans ^ permalink raw reply [flat|nested] 4+ messages in thread
