The last approach in the commit 8b3444852a2b ("sata_dwc_460ex: move to generic
DMA driver") to switch to generic DMA engine API wasn't tested on bare metal.
Besides that we expecting new board support coming with the same SATA IP but
with different DMA.
This series is targetting the following things:
- a few bug fixes to the original driver
- a part to fix the DMA engine usage and in particularly dw_dmac driver
- move driver to use generic PHY and "dmas" property which leads to update in DTS
The driver has been tested myself on Sam460ex and WD MyBookLive (apollo3g)
boards. In any case I ask Christian, Måns, and Julian to independently test and
provide Tested-by tag or an error report.
Series depends on previously published but not yet fully applied series [1].
The patches are also available via public branch [2].

Since v1:
- simplify patch 8 (David Laight)
- add Tested-by and Acked-by tags
