[PATCH v1 0/2] sata_dwc_460ex: move to generic DMA driver

[Andy Shevchenko]

The SATA implementation based on two actually different devices, i.e. SATA and
DMA controllers.

For Synopsys DesignWare DMA we have already a generic implementation of the
driver. Thus, the patch 1/2 converts the code to use DMAEngine framework and
dw_dmac driver.

In future it will be better to split the devices inside DTS as well like it's
done on other platforms and remove hardcoded parameters of DMA controller.

Besides it's a nice clean up it removes a lot of warnings produced by the
original code, that pissed off even Linus [1]. Though, this series doesn't
re-enable COMPILE_TEST for this module.

The driver is compile tested only on x86. So, it would be nice if anyone who
has either AMCC 460EX Canyonlands board or similar SATA controller in
possession can test this.
