Subject: [PATCH 6.18.y 1/2] arm64: dts: qcom: correct RBR opp entry
Date: Wed, 22 Jul 2026 14:00:47 -0400 [thread overview]
Message-ID: <20260722180048.2184180-1-sashal@kernel.org> (raw)
In-Reply-To: <2026072016-discern-gooey-8e42@gregkh>
From: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>
[ Upstream commit a5c21b9bd5f531e50141b0484faabb707b92f1e2 ]
DisplayPort Reduced Bit Rate uses link rate of 1.62 Gbps, the main link
clock should be 162 MHz. Having the incorrect frequency (160 MHz) in the
OPP table will result in selecting wrong link frequency. Correct the
entry in the OPP table.
