What is a good uart input driver module to start with?

Hello Linux input users, I have an embedded system for which I would like to write an input driver. The device is a CPLD connected to a uart on my system, with several buttons that I would like to represent as keyboard keys, as well as two arrays of input pins that are treated as axes. We have a working user space driver, which uses but it suffers from very high latency when the system is under load. I have read Documentation/input.txt and input-programming.txt. I'm just trying not to reinvent the wheel when it comes to a serial device with a non-standard way of expressing keys. -- Joshua Clayton Software Engineer UniWest 122 S. 4th Avenue Pasco, WA 99301 (509) 544-0720
