Each manufacturer has their own type of control. It +is not rare for the same manufacturer to ship different types of +controls, depending on the device. + +A Remote Controller interface is mapped as a normal evdev/input +interface, just like a keyboard or a mouse. So, it uses all ioctls +already defined for any other input devices. + +However, remove controllers are more flexible than a normal input +device, as the IR receiver (and/or transmitter) can be used in +conjunction with a wide variety of different IR remotes. + +In order to allow flexibility, the Remote Controller subsystem allows +controlling the RC-specific attributes via +:ref:`the sysfs class nodes `. -- cgit v1.2.3
