[PATCH 00/19] Qcom PCIe cleanups and improvements

From: Manivannan Sadhasivam

Hi,

This series brings in several code cleanups and improvements to the
Qualcomm PCIe controller drivers (RC and EP). The cleanup part mostly
cleans up the bitfield definitions and transitions to bulk APIs for clocks,
and resets. The improvement part renames the "mmio" region to "mhi" as per
Qualcomm's internal documentation EP driver and also adds the debugfs entry
to track link transition count in RC driver.

Testing
-------

I have tested this series on SDM845, SM8250 and SC8280XP based platforms.
However, I'm counting on Qualcomm folks CCed to do testing on older IPQ/APQ
platforms.

Merging Strategy
----------------

Binding and driver patches through PCI tree and DTS patches through Qcom
tree.

NOTE: For the sake of maintaining dependency, I've clubbed both cleanup and
improvement patches in the same series. If any of the maintainers prefer to
have them splitted, please let me know.

Thanks,
Mani
