   4 Subject: [PATCH] Revert "Revert "drm/vc4: Force HDMI to connected.""
   5
   6 This reverts commit 7da44d06540b4a191ecc74e943f3203577fce0df.
   7
   8 This breaks the driver on Pi3 as hotplug is implemented through a
   9 gpio expander owned by the GPU.
  10
  11 We need to extend the virtual gpio driver to support this, but for
  12 now assume hotplug is always enabled.
