[PATCH 7/8] arm64: dts: qcom: sm8750: Add t-power-on-us property for PCIe root port

From: Krishna Chaitanya Chundru

Date: Fri Sep 11 2026 - 02:54:02 EST


Currently the PCIe controller is not programming the T_POWER_ON value,
which can result in improper L1.2 exit behavior. Add the
t-power-on-us property to the PCIe root port so that this value is
correctly programmed during host initialization.
