Subject: [PATCH v1 0/2] Refactor MDP driver and add dummy component driver


This series depends on changes in
https://patchwork.kernel.org/patch/11528171/

We are adding a dummy MDP component driver so that all the components
are properly configured with IOMMUs and LARBs. This is required for
us to get hardware video decode working in 4.19, and possibly newer
kernels.

  [media] mtk-mdp: add driver to probe mdp components
  [media] mtk-mdp: use pm_runtime in MDP component driver
