Subject: [PATCH v6 09/10] arm64: dts: qcom: sc7180: Add support for HDCP in dp-controller

From: Sean Paul <seanpaul@...omium.org>

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. Now that these are supported, change the
compatible string to "dp-hdcp".
