Add Synopsys eDMA IP driver (version 0) 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
 - PCIe EndPoint glue-logic

Gustavo Pimentel (6):
  dma: Add Synopsys eDMA IP core driver
  dma: Add Synopsys eDMA IP version 0 support
  dma: Add Synopsys eDMA IP version 0 debugfs support
  dma: Add Synopsys eDMA IP PCIe glue-logic
  MAINTAINERS: Add Synopsys eDMA IP driver maintainer
  pci: pci_ids: Add Synopsys device id 0xedda
