[PATCH 2/3] arm64: dts: qcom: qrb2210: fix PM4125 regulator supply parent mappings
From: Rakesh Kota
Date: Fri Jul 17 2026 - 01:33:42 EST
The qrb2210-arduino-imola and qrb2210-rb1 DTS files used coarsely
grouped supply parent names that do not reflect the actual physical
pin connections on the PM4125 PMIC. Since supply rail connections
to PMIC pins are fixed in hardware, these grouped names were
inaccurate descriptions of the hardware topology.
Replace them with the correct per-group supply properties matching
the actual PM4125 pin connections, and align with the companion
driver change that sets supply names to NULL in the qcom_smd-regulator
descriptor so that the correct supply topology is captured in DT.
