Subject: [PATCH v2 0/5] dmaengine: ZynqMP PS PCIe DMA driver

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 PCIe driver for end points
Patch 4 adds Platform driver which handles DMA transactions
	for both PCI end points and Root DMA
Patch 5 describes device tree bindings for Root DMA
