J721S2: Add support for PCIE

[PATCH 0/2] J721S2: Add support for PCIE

Posted by Aswath Govindraju 4 years, 5 months ago

The following series of patches add support for single
instance of PCIe brought out on J721S2 common processor
board.

Notes:
- Applying this patch series **breaks the boot** of J721S2.
  This is because of the following commit,
  "19e863828acf PCI: j721e: Drop redundant struct device *"
  Dicussions are currently ongoing regarding the required
  fix.

- This needs to be merged after the following patch
  to avoid dtbs_check errors
