[PATCH 0/5] drm/vc4: Use the firmware to stop the display pipeline

[Maxime Ripard]

Hi,

The VC4 driver has had limited support to disable the HDMI controllers and
pixelvalves at boot if the firmware has enabled them.

However, this proved to be limited, and a bit unreliable so a new firmware
command has been introduced some time ago to make it free all its resources and
disable any display output it might have enabled.

This series takes advantage of that command to call it once the transition from
simplefb to the KMS driver has been done.

Let me know what you think,
Maxime

  drm/vc4: Remove conflicting framebuffers before callind bind_all
  drm/vc4: Notify the firmware when DRM is in charge
  ARM: dts: rpi: Add the firmware node to vc4
