Hello, Here is v3 the series to add support for PCIe on bcm2712 SoC used by RPi5. Previous v2 can be found at [1]. v2 -> v3 changes include: - Added Reviewed-by/Acked-by tags. - MIP MSI-X driver has been converted to MSI parent. - Added a new patch for PHY PLL adjustment need to succesfully enumerate PCIe endpoints on extension connector (tested with Pineboards AI Bundle + NVME SSD adapter card). - Re-introduced brcm,msi-offset DT private property for MIP interrupt-controller (without it I'm anable to use the interrupts of adapter cards on PCIe enxtension connector). For more info check patches.
