Subject: [PATCH 0/3] arm64: dts: imx: Fix PCIe EP vpcie-supply properties
Date: Sat,  9 May 2026 09:54:08 +0800	[thread overview]
Message-ID: <20260509015411.3218700-1-sherry.sun@nxp.com> (raw)

This series fixes PCIe endpoint mode vpcie-supply properties across
multiple i.MX platforms.

For PCIe endpoint mode, the vpcie-supply should either control the
actual M.2 power supply or be omitted if the power is always on and
uncontrollable.

Current issues:
- imx8dxl-evk and imx8qxp-mek: vpcie-supply references regulators that
  only control W_DISABLE1# signal, not actual power (which is always on)
- imx95-19x19-evk: vpcie-supply references wrong regulator (W_DISABLE1#
  instead of actual M.2 power)

So remove unnecessary properties for imx8dxl-evk and imx8qxp-mek, also
fix vpcie-supply to use correct regulator on imx95-19x19-evk.
