[PATCH v3 00/11] Add PCIe support for bcm2712

[Stanimir Varbanov <svarbanov@suse.de>]

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.
