Subject: [PATCH 3/3] arm64: dts: imx95-19x19-evk: Fix PCIe EP vpcie-supply
Date: Sat,  9 May 2026 09:54:11 +0800	[thread overview]
Message-ID: <20260509015411.3218700-4-sherry.sun@nxp.com> (raw)
In-Reply-To: <20260509015411.3218700-1-sherry.sun@nxp.com>

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.

Fixes: 58bea81052d0 ("arm64: dts: imx95: add pcie1 ep overlay file and create pcie-ep dtb files")
