> For some of the platforms (e.g. SDM660, SDM630, MSM8996, etc.) it is
> possible to support this platform via the DPU driver (e.g. to provide
> support for DP, multirect, etc). Add a modparam to be able to switch
> between these two drivers.
>
> All platforms supported by both drivers are by default handled by the
> MDP5 driver. To let them be handled by the DPU driver pass the
> `msm.prefer_mdp5=false` kernel param.
