Thanks for getting back to my patchsets. The 3rd series is still under
review (see below for details). Here is the summary regarding the
patchsets state:

[1: Done v5] PCI: dwc: Various fixes and cleanups
The latest lore
Link: https://lore.kernel.org/linux-pci/20220624143428.8334-1-Sergey.Semin@baikalelectronics.ru/
You've already merged it in here:
Link: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/ctrl/dwc

[2: Done v4] PCI: dwc: Add hw version and dma-ranges support
The latest lore
Link: https://lore.kernel.org/linux-pci/20220624143947.8991-1-Sergey.Semin@baikalelectronics.ru

[3: In-progress v3] PCI: dwc: Add extended YAML-schema and Baikal-T1 support
The latest lore
Link: https://lore.kernel.org/linux-pci/20220610085706.15741-1-Sergey.Semin@baikalelectronics.ru/
This series, you are having difficulties to apply, is still under Rob'
review. I've addressed all your comments locally in my repo, but Rob'
didn't respond on some of my questions (there are several principal
aspects of the dt-bindings patches he didn't like). First he used to
be in vacation, then he just missed several of my email messages, but
responded on another ones. Pings didn't work either. Then I thought
the merge-window was opened so I has stopped bothering him for some
time.) So I'll resend the series as is one more time today then.
Hopefully he'll get back to it soon.

[4: Done v3] dmaengine: dw-edma: Add RP/EP local DMA support
The latest lore
Link: https://lore.kernel.org/linux-pci/20220610091459.17612-1-Sergey.Semin@baikalelectronics.ru/
The series review is done. It has even got Vinod' Ab tag. But I need
to resend it (will do this today) since it needs to be rebased on the
latest Frank Li patchset. Frank series is in your repo already:
Link: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/ctrl/dwc-edma

So if you aren't going to merge the DW PCIe/eDMA related series in on this
merge window, please collect my and Frank work in a single branch of
yours (pci/ctrl/dwc-edma), since my patchset #4 depends on his series
and the patchsets #3, #2 and #1 described above.
