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.
