Hi Eizan,

Thank you for your patch.

> A virtual device that is probed by the mtk_mdp_core driver is
> instantiated by the mtk_mmsys driver.
>
> This better reflects the logical organization of the hardware and
> driver: there are a number of hardware blocks that are used by the MDP
> that have no strict hierarchy, and the software driver is responsible
> for driving them properly.
