arm64: dts: imx95-15x15-frdm: Move PCIe PERST# and vpcie supply to Root Port node

[PATCH] arm64: dts: imx95-15x15-frdm: Move PCIe PERST# and vpcie supply to Root Port node

Posted by Sherry Sun (OSS) 1 month, 1 week ago

From: Sherry Sun <sherry.sun@nxp.com>

Describing the PCIe PERST# and vpcie supply properties under the Host
Bridge node is now deprecated. Add the PERST# (reset-gpios) and the
power regulator (vpcie3v3-supply) in the pcie0_port0 Root Port node.

Since i.MX95 is the new platform that under development phase, it should
be fine to simply move the PERST# and power supply properties.
