Subject: [PATCH 0/8] dmaengine: hisilicon: Add support for hisi dma driver

The HiSilicon IP08 and HiSilicon IP09 are DMA iEPs, they share the
same pci device id but different pci revision and register layouts.

The original version supports HiSilicon IP08 but not HiSilicon IP09.
This series support DMA driver for HIP08 and HIP09:

1. Fix bugs for HIP08 DMA driver
	- Disable hardware channels when driver detached
	- Update cq_head whenever accessed it
	- Support multi-thread for one DMA channel
2. Use macros instead of magic number
3. Add support for HIP09 DMA driver
4. Add debugfs for HIP08 and HIP09 DMA driver
5. Add myself as maintainer of hisi_dma.c
