Subject: [PATCH v5 09/10] arm64: dts: qcom: sc7180: Add support for HDCP in dp-controller
Date: Mon, 11 Apr 2022 20:47:38 +0000 [thread overview]
Message-ID: <20220411204741.1074308-10-sean@poorly.run> (raw)
In-Reply-To: <20220411204741.1074308-1-sean@poorly.run>
From: Sean Paul <seanpaul@chromium.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".
