[PATCH v3 00/19] Qcom PCIe cleanups and improvements

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 adds the debugfs entries to track link
transition counts in RC driver.

Testing
-------

This series has been tested on SDM845, SM8250, SC8280XP, IPQ4019 based
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

Changes in v3:

* Introduced init_debugfs callback for defining the debugfs interface specific
to IP versions
* Added a debugfs patch for v2.4.0
* Added a patch to rename qcom_pcie_config_sid_sm8250() function
* Added tested-by for patch 11/19

Changes in v2:

* Moved the "mhi" region to last in the binding and dtsi's
* Dropped the patches renaming the "mmio" region
