Subject: [PATCH v6 08/10] dt-bindings: msm/dp: Add bindings for HDCP registers
Date: Wed, 18 Jan 2023 19:30:13 +0000 [thread overview]
Message-ID: <20230118193015.911074-9-markyacoub@google.com> (raw)
In-Reply-To: <20230118193015.911074-1-markyacoub@google.com>
From: Sean Paul <seanpaul@chromium.org>
This patch adds the bindings for the MSM DisplayPort HDCP registers
which are required to write the HDCP key into the display controller as
well as the registers to enable HDCP authentication/key
exchange/encryption.
We'll use a new compatible string for this since the fields are optional.
