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

From: Ravi Shankar Jonnalagadda
Date: Fri Sep 08 2017 - 08:24:09 EST


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
