Currently the IR input handling of drivers/media/dvb/ttpci/budget-ci.c
requires a rc5_device module option which specifies the rc5 device code
to listen to (or as an alternative, all devices). This means, among
other things, that multiple remotes can't be used with different
keymaps.
My idea was to drop the module parameter and allow all rc5 device and
command combinations to be mapped using one keyboard map.
rc5 device codes are 5 bits, command codes are 6 bits, giving a total of
2048 possible keycodes.
However, the input subsystem is currently limited to 512 entries. So my
question is whether it would be possible to extend that and/or make the
size of the keymap (the keybit member of struct input_dev) dynamic?
