As far as I remember (I may be > wrong again), that did not happen. I don't seem to remember seeing anything from ST Ericsson... While my memory doesn't always serve me well, I would imagine I'd remember if I'd seen code based on my code. Ah, found them from fbdev mail archive. I was rather busy at that period, I didn't really read the mailing lists. I totally agree with you that we should have a common panel interface layer. As I said, I've had it as a target for a long time. And hopefully now that I moved from Nokia to TI I'll finally have time to work on it also. Thanks for pointing me to the MCDE stuff. I doesn't seem to be merged, though. I need to contact them and see if they're still interested in working on the common interface.
