This patch adds the register ranges required for HDCP key injection and HDCP TrustZone interaction as described in the dt-bindings for the sc7180 dp controller.
Can you please mention why this is only done for trogdor and not sc7180 as a whole?
Now that these are supported, change the compatible string to "dp-hdcp".
I don't see this change in the patch.

This hunk stands on its own, following the DT binding changes I did earlier. Would you mind spinning it off so I can merge it separately?
Thanks, Bjorn
