Subject: [PATCH 0/7] dmaengine: add support for sama7g5 based at_xdmac

This series adds support for sama7g5-based at_xdmac.

In sama7g5, the XDMAC is present in a slightly modified form. This series
tries to adapt the existing driver to the differences.
According to the compatible string, we select one of two possible
layouts, which hold the differences in registermap and supported features.

Thanks!
