[PATCH v5 -next 00/11] Add PCIe support for bcm2712

[Stanimir Varbanov]

Here is v5 of the series which aims to add support for PCIe on bcm2712 SoC
used by RPi5. Previous v4 can be found at [1].

Based the series on linux-next because of vc4 gpu node in bcm2712.dtsi.

v4 -> v5 changes include:
 - Addressed comments to interrupt-controller driver. (Thomas)
 - Fixed DTB warnings  broadcom/bcm2712-rpi-5-b.dtb.
 - New patch in the series to fix missing of_node_put.
 - New patch to make a softdep to a MIP MSI-X driver.
 - Dropped the patch which adds MSI-X support in pcie-brcmstb driver,
   and instead use DT dma-ranges to pass the needed information. (Jim)

For more detailed info check patches.

Comments are welcome!
