[PATCH v2 10/12] arm64: dts: qcom: sc8280xp-x13s: disable ASPM L0s for Wi-Fi

From: Johan Hovold
Date: Fri Feb 23 2024 - 10:25:40 EST


Enabling ASPM L0s on the Lenovo Thinkpad X13s results in Correctable
Errors (BadTLP, Timeout) when accessing the Wi-Fi controller so disable
it for now.

Fixes: 9f4f3dfad8cf ("PCI: qcom: Enable ASPM for platforms supporting 1.9.0 ops")
