Subject: arm64: dts: imx95-19x19-evk: Fix PCIe EP vpcie-supply
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=596d0f9f4fefffbf783ab26cfa90cf50f5dd6bb0;p=thirdparty%2Flinux.git

arm64: dts: imx95-19x19-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 imx95-19x19-evk:
- reg_pcie0 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.
