The comment is misleading, "t6000-atcphy-dp-only" would be for M1
Pro/Max Macbooks. M2 Pro/Max Macbooks use the same design so the
corresponding "apple,t6020-atcphy-dp-only" compatible is missing.
I'm not sure this is the correct design though as the HW block is
identical to "apple,t6000-atcphy".
I think it might be better to have either the DRM KMS driver or a
custom DP->HDMI drm_bridge switch the mode to DP-only.
Or atcphy could initialize itself to DP-only based on the available
ports.
Doesn't sound like this should be a different compatible. There's a
'phy-mode' property or you can define the mode in the 'phys' cells for
the DP controller.
Okay, makes sense. I'll drop the compatible.
I've only found "intel,phy-mode" inside bindings/phy but we can figure
this out later once we actually get to upstreaming what's required for
DisplayPort and mostly focus on USB3 for this series.
