Subject: [PATCH] arm64: dts: rockchip: orangepi-5: fix PCIe 3.3V regulator voltage
Date: Fri, 24 Oct 2025 20:38:20 +0300 [thread overview]
Message-ID: <20251024173830.49211-1-xakep.amatop@gmail.com> (raw)
The vcc3v3_pcie20 fixed regulator powers the PCIe device-side 3.3V
rail for pcie2x1l2 via vpcie3v3-supply. The DTS mistakenly set its
regulator-min/max-microvolt to 1800000. Correct both to 3300000
to match the rail name, the PCIe/M.2 power requirement, and the
actual hardware wiring on Orange Pi 5.
