Hello,

This series contains improvements to the Qualcomm PCIe Endpoint controller
driver. The major improvements are the addition of SM8450 SoC support and
debugfs interface for exposing link transition counts.

This series has been tested on SM8450 based dev board.

Thanks,
Mani

Changes in v3:

* Removed the maxItems property from "items" list
* Reworded the debugfs patch
* Dropped the eDMA patch since that depends on ongoing eDMA series from Sergey
* Added two new patches that helps in saving power during idle and low power
state

Changes in v2:

* Fixed the comments on bindings patches
* Added Ack from Krzysztof
