The panel also supports RGB888 output. When RGB666 mode is used instead, the two extra lanes per component are grounded. In the future, it might become necessary to introduce a dedicated device-tree property to specify the bus format to use instead of the default one for the panel. This will allow supporting different bus formats for the same panel modes.
