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!
