Subject: [PATCH 3/3] arm64: dts: rockchip: drop max-link-speed = <2> in helios64 PCIe
Date: Sat, 15 Nov 2025 06:10:58 -0300 [thread overview]
Message-ID: <53332edec449b84d8a962f2b5995667766359772.1763197368.git.geraldogabriel@gmail.com> (raw)
In-Reply-To: <cover.1763197368.git.geraldogabriel@gmail.com>
Shawn Lin from Rockchip strongly discourages attempts to use their
RK3399 PCIe core at 5.0 GT/s speed, citing concerns about catastrophic
failures that may happen. Even if the odds are low, drop from last user
of this property for the RK3399 platform, helios64.
Fixes: 755fff528b1b ("arm64: dts: rockchip: add variables for pcie completion to helios64")
