Subject: [PATCH v3 13/14] arm64: dts: qcom: sc7180: Add support for HDCP in dp-controller
Date: Fri, 1 Oct 2021 11:11:42 -0400 [thread overview]
Message-ID: <20211001151145.55916-14-sean@poorly.run> (raw)
In-Reply-To: <20211001151145.55916-1-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".
Signed-off-by: Sean Paul <seanpaul@chromium.org>
