From 65c16cd0def939e86552f1b22ffdbd63b69eebe4 Mon Sep 17 00:00:00 2001 From: Sherry Sun Date: Tue, 19 May 2026 13:54:31 +0800 Subject: [PATCH] arm64: dts: imx943-evk: Fix PCIe EP vpcie-supply The vpcie-supply property should reference the regulator that controls the actual M.2 power supply, not the W_DISABLE1# signal. On imx943-evk: - reg_m2_wlan controls M.2 W_DISABLE1# signal - reg_m2_pwr controls the actual M.2 power supply Fix the vpcie-supply to use reg_m2_pwr for proper power control in PCIe endpoint mode.
