| Currently, most analog and digital devices have a Infrared input for |
| remote controllers. 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 <remote_controllers_sysfs_nodes>`. |
