Subject: [PATCH v1 4/4] arm64: dts: qcom: x1e80100-qcp: Enable HBR3 on external DPs
Date: Thu, 27 Feb 2025 00:12:12 +0100 [thread overview]
Message-ID: <20250226231436.16138-5-alex.vinarskis@gmail.com> (raw)
In-Reply-To: <20250226231436.16138-1-alex.vinarskis@gmail.com>
When no link frequencies are set, msm/dp driver defaults to HBR2 speed.
Explicitly list supported frequencies including HBR3/8.1Gbps for all
external DisplayPort(s).
