24353b8bb4 DMA-API: dma: dw_dmac.c: convert to use dma_coerce_mask_and_coherent() 
This code sequence:
	if (!pdev->dev.dma_mask) {
		pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
		pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32);
	}
bypasses the architectures check on the DMA mask.  It can be replaced
with dma_coerce_mask_and_coherent(), avoiding the direct initialization
of this mask.

be480dcbb5 dma: dw: append MODULE_DEVICE_TABLE for ACPI case 
In rare cases (mostly for the testing purposes) the dw_dmac driver might be
compiled as a module as well as the other LPSS device drivers (I2C, SPI,
HSUART). When udev handles the event of the devices appearing the dw_dmac
module is missing. This patch will fix that.

9cade1a46c dma: dw: split driver to library part and platform code 
To simplify the driver development let's split driver to library and platform
code parts. It helps us to add PCI driver in future.
