Subject: [PATCH v4 00/10] Add PCIe support for bcm2712

Here is v4 of the series which aims to add support for PCIe on bcm2712 SoC
used by RPi5. Previous v3 can be found at [1].

v3 -> v4 changes include:
 - Addressed comments on the interrupt-controller driver (Thomas)
 - Moved "Reuse config structure" patch earlier in the series (Bjorn)
 - Merged "Avoid turn off of bridge reset" into "Add bcm2712 support" (Bjorn)
 - Fixed DTB warnings on broadcom/bcm2712-rpi-5-b.dtb 

For more detailed info check patches.

Comments are welcome!
