[PATCH] arm64: dts: qcom: qcm6490-idp: Enable PCIe1

From: Sushrut Shree Trivedi

Date: Thu Feb 12 2026 - 07:08:22 EST


Remove PCIe1 clocks from protected-list and enable PCIe1 controller
and its corresponding PHY nodes on qcm6490-idp platform.

PCIe1 is used to connect NVMe based SSD's on this platform.
