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.
