    Subject[PATCH 00/11] drm/msm: Add Display Stream Compression Support
    Date
    Display Stream Compression (DSC) compresses the display stream in host which
    is later decoded by panel. This series enables this for Qualcomm msm driver.
    This was tested on Google Pixel3 phone which use LGE SW43408 panel.

    The changes include adding DT properties for DSC then hardware blocks
    support required in DPU1 driver and support in encoder. We also add support
    in DSI and introduce required topology changes.

    In order for panel to set the DSC parameters we add dsc in drm_panel and set
    it from the msm driver.

    Complete changes which enable this for Pixel3 along with panel driver (not
    part of this series) and DT changes can be found at:
    git.linaro.org/people/vinod.koul/kernel.git pixel/dsc_v1

    Comments welcome!

    Changes since RFC:
    - Drop the DT binding patch as we derive the configuration from panel
    - Drop the drm api patch as we no longer need it (use pps drm api)
    - Fix comments raised by Dimitry
    - Add dsc parameters calculation from downstream
