[PATCH 1/7] arm64: dts: rockchip: Remove unneeded vcc_3v3_pcie20 on NanoPC-T6
From: Diederik de Haas
Date: Fri Aug 28 2026 - 07:46:25 EST
The ``vcc_3v3_pcie20`` regulator, identified in the schematic with
``VDD3V3_25GLAN[_B]`` is only separated from ``VCC_3V3_S3`` with a ferrite
bead. So there's no need to define a separate regulator for that.
