4 Subject: [PATCH 358/381] Revert "Revert "drm/vc4: Force HDMI to connected.""
6 This reverts commit 7da44d06540b4a191ecc74e943f3203577fce0df.
8 This breaks the driver on Pi3 as hotplug is implemented through a
9 gpio expander owned by the GPU.
11 We need to extend the virtual gpio driver to support this, but for
12 now assume hotplug is always enabled.
