[PATCH 0/7] drm/msm: rework the ties between KMS and GPU parts of the driver
Posted by Dmitry Baryshkov 10 months ago
Currently the KMS and GPU parts of the msm driver are pretty much
intertwined. It is impossible to register a KMS-only device and
registering a GPU-only DRM device requires modifying the DT.  Not to
mention that binding the GPU-only device creates an interim platform
devices, which complicates IOMMU setup.

Rework the driver:
- Make it possible to disable KMS parts (if MDP4, MDP5 and DPU drivers
  are disabled).
- Register GPU-only devices without an interim platform device.
- Add module param that makes msm driver register GPU and KMS devices
  separately.
