[PATCH v3 2/3] arm64: dts: rockchip: remove vcc_3v3_pmu regulator for Radxa E52C
From: Chukun Pan
Date: Mon Sep 01 2025 - 06:02:09 EST
According to Radxa E52C Schematic V1.2 [1] page 5, vcc_3v3_pmu
is directly connected to vcc_3v3_s3 via a 0 ohm resistor.
The vcc_3v3_pmu is not a new regulator, so remove it.
