++Name:   gpio-ir
++Info:   Use GPIO pin as rc-core style infrared receiver input. The rc-core-
++        based gpio_ir_recv driver maps received keys directly to a
++        /dev/input/event* device, all decoding is done by the kernel - LIRC is
++        not required! The key mapping and other decoding parameters can be
++        configured by "ir-keytable" tool.
