Note that I'm in an NTSC area, PAL and other methods are left as an exercise for somebody who actually has that hardware. http://www.shspvr.com/forum/viewtopic.php?t=1378 Let me reiterate the following point: If you're planning on writing drivers DO NOT look at that code. > Note, I don't have this quite working with i2c-algo-bit yet, so I've either > got a bug, or I've misread something. I did get this working. Curiously it didn't seem to like readl()/writel(), but was fine with memcpy(,,4) [which becomes __constant_memcpy()]. If I've parsed all the #defines and inlines correctly, it should have simply been the difference of a volatile access in the case of the *l() functions to the ioremapped card memory. Kernel 2.4.15 with Viro patches. Uh, oh yeah, this is also MyFirstDriver(tm) so more than likely I missed something obvious. There are some differences in both my implementations, so isn't exactly an apples-to-apples comparison. When I get a few spare cycles, I'm going to revisit my code. John
