Re: [PATCH 1/1 try#2] [INPUT] keypad driver: Added support for OpenCores Keyboard Controller

Dear Vojtech,

I think that a 1:1 mapping between linux keycodes and what keyboard 
sends is right, because the scan code to key code conversion is already 
programmed and done inside the FPGA code.

Best regards,

Javier
