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 and maybe specify it in the mode description instead of panel description so that the appropriate mode can be selected for each bus format.
