| description: |
| Apple SoCs contain a 2-wire interface called DWI. On some Apple iPhones, |
| iPads and iPod touches with a LCD display, 1-2 backlight controllers |
| are connected via DWI. Interfacing with DWI controls all backlight |
| controllers at the same time. As such, the backlight controllers are |
| treated as a single controller regardless of the underlying |
| configuration. |
