ZynqMP devices have PCIe Bridge along with DMA in PS.
These devices can be configured as either PCIe Endpoints
or as PCIe Root Complex.
This patch series shall provide a driver to initiate
transactions using this DMA.
Single platform driver shall handle both EndPoint and
Root DMA transfers.
Patch 1 enables Root DMA register translation and
	interrupts
Patch 2 corrects styling errors seen with checkpatch
Patch 3 adds DMA driver functionality for both PCI
	end points and Root DMA
Patch 4 describes device tree bindings for Root DMA
