Subject: [PATCH 1/7] arm64: dts: rockchip: Remove unneeded vcc_3v3_pcie20 on NanoPC-T6
Date: Fri, 28 Aug 2026 13:43:01 +0200	[thread overview]
Message-ID: <20260828114530.1315798-2-diederik@cknow-tech.com> (raw)
In-Reply-To: <20260828114530.1315798-1-diederik@cknow-tech.com>

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.
