[PATCH 3/8] arm64: dts: qcom: monaco: Add t-power-on-us property for PCIe root ports
From: Krishna Chaitanya Chundru
Date: Fri Sep 11 2026 - 02:53:27 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 ports so that this value is
correctly programmed during host initialization.
