Current order is:

[PATCH 01/12] PCI/switchtec: Use dma_set_mask_and_coherent()
[PATCH 02/12] PCI/switchtec: Fix vep_vector_number ioread width
[PATCH 03/12] PCI/switchtec: Add support for new events
[PATCH 04/12] PCI/switchtec: Remove redundant valid PFF number count
[PATCH 05/12] PCI/switchtec: Move check event id from mask_event() to switchtec_event_isr()
[PATCH 06/12] PCI/switchtec: Introduce Generation Variable
[PATCH 07/12] PCI/switchtec: Separate out gen3 specific fields in the sys_info_regs structure
[PATCH 08/12] PCI/switchtec: Add gen4 support in struct sys_info_regs
[PATCH 09/12] PCI/switchtec: Add gen4 support in struct flash_info_regs
[PATCH 10/12] PCI/switchtec: Add permission check for the GAS access MRPC commands

10/12 looks lonely in the middle of the gen4 stuff, and it looks like
it's unrelated to gen3/gen4? Maybe it could be moved up after 05/12?

[PATCH 11/12] PCI/switchtec: Introduce gen4 variant IDS in the device ID table
[PATCH 12/12] PCI: Apply switchtec DMA aliasing quirk to GEN4 devices

I speculatively reordered the permission check patch and applied these
to my pci/switchtec branch for v5.6 (reverse order from "git log"):

b96abab6314f ("PCI/switchtec: Add permission check for the GAS access MRPC commands")
5f23367bd4df ("PCI/switchtec: Move check event ID from mask_event() to switchtec_event_isr()")
6722d609bc82 ("PCI/switchtec: Remove redundant valid PFF number count")
3f3a521ecc81 ("PCI/switchtec: Add support for intercom notify and UEC Port")
9375646b4cf0 ("PCI/switchtec: Fix vep_vector_number ioread width")
aa82130a22f7 ("PCI/switchtec: Use dma_set_mask_and_coherent()")

If you rework any of the subsequent ones, you can just post those
without reposting these first six.
