Subject: [PATCH v2 0/3] drm/msm: Better unknown GPU handling

Detect earlier if the GPU is supported, and skip binding the GPU
sub-component if not.  This way the rest of the driver can still
probe and get working display if the only thing unsupported is
the GPU.

v2: use %pOF [Dmitry]

Rob Clark (3):
  drm/msm: Rename add_components_mdp()
  drm/msm/adreno: Pass device_node to find_chipid()
  drm/msm/adreno: Check for recognized GPU before bind
