Hi all,

I found a great blog post [1], which described the reverse engineering
process of the GPIO control methods present on this device.

In summary, these methods expose some debugging capabilities of the RGB
lighting controller present on Dell gaming laptops. See [Patch 2] for
more info.

Exposing these methods to DebugFS is useful for developers exploring
this RGB controllers (myself included).

Thanks for your feedback!
