Subject: [PATCH v2 0/2] Refactor MDP driver and add dummy component driver


This series depends on all changes in the series:
https://patchwork.kernel.org/patch/11530275/

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.

Changes in v2:
- remove empty mtk_mdp_comp_init
- update documentation for enum mtk_mdp_comp_type
- remove comma after last element of mtk_mdp_comp_driver_dt_match

Eizan Miyamoto (2):
  [media] mtk-mdp: add driver to probe mdp components
  [media] mtk-mdp: use pm_runtime in MDP component driver
