Fixed encoder.ko makefile and missing #include
Changes to the encoder driver
It now uses an entry in sysfs instead of /dev. Also it now compiles.
Added irq_set_irq_type to encoder driver
Added actual reads from hardware to encoder.ko
Not yet tested on Gumstix (especially since I don't think we have theencoders yet).
Added kernel module for quad encoders
The kernel module is not finished yet. Also, added various config filesthat go on every Gumstix. It would be nice to have an automated scriptfor installing them.
