ata: dwc: add DMADEVICES dependency

2016-05-12T16:04:13+00:00

The dwc_460ex SATA driver has become available on non-powerpc architectures
and may cause randconfig build errors when CONFIG_DMADEVICES is not set
and SATA_DWC_OLD_DMA is enabled:

warning: (SATA_DWC_OLD_DMA) selects DW_DMAC_CORE which has unmet direct dependencies (DMADEVICES)
ERROR: "dw_dma_probe" [drivers/ata/sata_dwc_460ex.ko] undefined!
ERROR: "dw_dma_remove" [drivers/ata/sata_dwc_460ex.ko] undefined!

This adds an explcit Kconfig dependency to CONFIG_SATA_DWC so we
cannot run into broken configurations. While it would also be
possible to build the driver with both CONFIG_DMADEVICES
and SATA_DWC_OLD_DMA disabled, that case is not useful because
there is no fallback to PIO mode when the DMA engine is not
usable.

ata: sata_dwc_460ex: use "dmas" DT property to find dma channel

2016-05-10T16:29:19+00:00

Currently this driver only works with a DesignWare DMA engine which it
registers manually using the second "reg" address range and interrupt
number from the DT node.

This patch makes the driver instead use the "dmas" property if present,
otherwise optionally falling back on the old way so existing device
trees can continue to work.

With this change, there is no longer any reason to depend on the 460EX
machine type so drop that from Kconfig.

ata: sata_dwc_460ex: select only core part of DMA driver

2016-05-10T16:29:18+00:00

There is no need to have a platform driver compiled since the DMA driver is
used as a library.
