Simon, I see the following v2 patches were applied, but don't see you replied the patch thread to mention it's been applied.
- x86: fsp: Call fsp_init_phase_pci() in pci_uclass_post_probe()
- fdtdec: Fix possible infinite loop in fdtdec_get_pci_vendev()
- dm: pci: Save devfn without bus number in pci_uclass_child_post_bind()
I assume these patches look good, so I don't include those patches in the v3 series. Let me know if there is any issue.
They are fine, thanks.
Changes in v3 respin:
- Fix typo of 'tree'
Changes in v3:
- Rebase on u-boot-x86/master
- Drop v2 patches which were already applied

Since this is a special case for PCI I think it is best that this check goes here instead of dm_scan_fdt_node().
