I have replied with my Tested-by to the patch at [2], which has landed
in the linux-next as the commit 20f1bfb8dd62 ("PCI: qcom:
Add support for handling MSIs from 8 endpoints"). However lately I
noticed that during the tests I still had 'pcie_pme=nomsi', so the
device was not forced to use higher MSI vectors.
After removing this option I noticed that hight MSI vectors are not
delivered on tested platforms. After additional research I stumbled upon
a patch in msm-4.14 ([1]), which describes that each group of MSI
vectors is mapped to the separate interrupt. Implement corresponding
mapping.
The first patch in the series is a revert of [2] (landed in pci-next).
Either both patches should be applied or both should be dropped.
Patchseries dependecies: [3] (for the schema change).
Changes since v10:
- Remove has_split_msi_irqs flag. Trust DT and use split MSI IRQs if
they are described in the DT. This removes the need for the
pcie-qcom.c changes (everything is handled by the core (suggested by
Johan).
You could also mention the rebase and fixed warnings with less than
eight msi.

Looks like you used the wrong offsets from HEAD or something when
generating the series as the first two patches ([1] above, which is not
yet in linux-next, and the dw_pcie_free_msi() fix) are now missing and
the last patch is new and unrelated.
Ugh. Please excuse me.
