Subject: [PATCH 355/423] Revert "Revert "drm/vc4: Force HDMI to connected.""
|
|
|
|
This reverts commit 7da44d06540b4a191ecc74e943f3203577fce0df.
|
|
|
|
This breaks the driver on Pi3 as hotplug is implemented through a
|
|
gpio expander owned by the GPU.
|
|
|
|
We need to extend the virtual gpio driver to support this, but for
|
|
now assume hotplug is always enabled.
