Hi folks, Recently, I ported Linux to a previously unsupported device (it uses pxa270 processer, so most of the work was already done), and I had a couple of issues that I hope you could help me with. 1) I wrote a new 'multi-function' driver for the STMPE2401 gpio expander, which also has a keypad controller, 3 pwm channels, and a rotator input, and I would appreciate it if a couple of people could review it for me so that it could be submitted upstream. So far, only the keypad function is implemented because my device doesn't use the others. However, I've already coded in most of the structure for the other device functions but they just return -ENOSYS on probe. I'm sure that someone with sufficient experience could probably look at my driver and give me a few tips on how to improve it before submission. Which leads me to my next question... 2) currently the input is a bit complicated - there are a couple of different modifier keys, and I'm not really sure where to start to have userspace handle the scancode-keycode mapping. Right now it's done in kernel mode in a small callback function. Can somebody point me in the right direction? It would be nice if the keypad worked at the console and also in X or other graphical environments. Currently I'm trying to get it to work in Android, which just uses the typical event interface for key-remapping. I suppose one way to do it would be to have the kernel dynamically switch based on if the event device is open... still it's a bit confusing. Any tips?
