I think this paragraph is obsolete, since the "Enable designware PCI
EP EDMA locally" series you reference is already upstream:
https://git.kernel.org/linus/94d13317bef3

What remains are items 3 and 4.

3 is mostly drivers/pci/ and DT bindings (Lorenzo).  4 is mostly
drivers/dma/dw-edma/ stuff (Gustavo).  I guess Lorenzo and Gustavo can
figure out where it makes the most sense to merge it.
