Hi,
This series enables ASPM by default on the host bridge and devices of selected Qcom platforms.
The motivation behind enabling ASPM in the controller driver is provided in the commit message of patch 2/2.
This series has been tested on SC8280-CRD and Lenovo Thinkpad X13s laptop and it helped save ~0.6W of power during runtime.

Changes in v2:
* Rebased on top of v6.6-rc1
