This is RFC patch series which define a new PCIe slot-power-limit DT property (first patch) and show example how to use it in pci-aardvark.c driver (second and third patch). Second and third patches depends on other pci-aardvark patches which are under review. I included them here just to show how this new slot-power-limit DT property can be used. Please let me know what do you think about this approach of defining Slot Power Limit in DTS file.
