| Series | Apple DWI backlight driver | expand |
Apple SoCs come with a 2-wire interface named DWI. On some iPhones, iPads and iPod touches 1-2 backlight controllers are attached via this interface. Though, to software using this interface, there is effectively only one controller to worry about since the registers changes the brightness setting on all controllers at the same time. This series adds a backlight driver for backlight controllers connected this way.
