Subject: [PATCH] drm/vc4: Ensure vc4_hdmi doesn't use 2711 HPD
|
|
registers on Pi0-3
|
|
|
|
The existing logic was flawed in that it could try reading the
|
|
2711 specific registers for HPD on a CM1/3 where the HPD GPIO
|
|
hadn't been defined in DT.
|
|
|
|
Ensure we don't do the 2711 register read on invalid hardware,
|
|
and then
|
