>
> 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.
