Subject: [PATCH v4 00/12] Improvements to the Qcom PCIe Endpoint driver

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.

NOTE: Since the bindings are ACKed, the whole series could be merged to the
PCI tree.

Thanks,
Mani

Changes in v4:

* Collected tags for bindings patches
* Reworded the subject of patch 2/12

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
