From 4f4c905e6a2a4e884f4e9b7326c94fac3500e0f9 Mon Sep 17 00:00:00 2001 From: Varadarajan Narayanan Date: Fri, 7 Feb 2025 13:05:45 +0530 Subject: [PATCH] arm64: dts: qcom: ipq9574: Fix USB vdd info USB phys in ipq9574 use the 'L5' regulator. The commit ec4f047679d5 ("arm64: dts: qcom: ipq9574: Enable USB") incorrectly specified it as 'L2'. Because of this when the phy module turns off/on its regulators, the wrong regulator is turned off/on resulting in 2 issues, namely the correct regulator related to the USB phy is not turned off/on and the module powered by the incorrect regulator is affected.
