Add Synopsys eDMA IP driver (version 0 and for EP side only) to Linux
kernel. This IP is generally distributed with Synopsys PCIe EndPoint IP
(depends of the use and licensing agreement), which supports:
 - legacy and unroll modes
 - 16 independent and concurrent channels (8 write + 8 read)
 - supports linked list (scatter-gather) transfer
 - each linked list descriptor can transfer from 1 byte to 4 Gbytes
 - supports cyclic transfer
 - PCIe EndPoint glue-logic

This patch series contains: 
 - eDMA core + eDMA core v0 driver (implements the interface with
 DMAengine controller APIs and interfaces with eDMA HW block)
 - eDMA PCIe glue-logic reference driver (attaches to Synopsys EP and
 provides memory access to eDMA core driver)
 - eDMA Test driver (is a reference driver which aims to test the eDMA,
 which uses DMAengine client APIs)

Gustavo Pimentel (7):
  dmaengine: Add Synopsys eDMA IP core driver
  dmaengine: Add Synopsys eDMA IP version 0 support
  dmaengine: Add Synopsys eDMA IP version 0 debugfs support
  PCI: Add Synopsys endpoint EDDA Device id
  dmaengine: Add Synopsys eDMA IP PCIe glue-logic
  MAINTAINERS: Add Synopsys eDMA IP driver maintainer
  dmaengine: Add Synopsys eDMA IP test and sample driver
