Hi Mauro. How do you want to proceed with the nuvoton wakeup I initially set out to do? To wake up with nuvoton-cir we need to program several raw ir pulse/space lengths to the hardware and not a scancode. James's approach doesn't support this. To keep things simple maybe module parameters in my first patch (http://www.mail-archive.com/linux-media@vger.kernel.org/msg69782.html) are then the best thing to do for nuvoton? Other drivers can probably adapt to the suggested filter api. -Antti -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
