This series first fix a bug related with runtime pm. Then do three clean
up. After that, we add three new features: per channel irq support,
dma-channel-mask support and polled mode support.
Since v3:
- rebase on the latest rc1
Since v2
- fix typo
- add reason why we need to runtime resume before reading reg in

Hi Vinod,
I still kept patch2 in v2, because I think the irq has been disabled
from the dw-axi-dma side, so the irq won't be fired any more. If you
prefer to keep the devm_free_irq() just ignore patch2.
Thanks a lot.
