Subject: [PATCH 0/9] 8250: AMD Carrizo UART PL300 DMA enablement

Hi all,

As AMD carrizo UART device is compatible with 8250 and has pl330 DMA
IP, our uart driver is serial:8250 and DMA engines are registered by
driver/dma/pl330. The following patches are made, in order to enable
DMA.

Firstly, we add an universal ACPI amba glue layer to create an amba
device based on ACPI table. Then we alter 8250/Kconfig to support
AMD 8250 device and add quirk for AMD specific request.
Secondly, since pl330 driver only provides dma engine for platform
devices, we add an acpi dma engine interface.
Then we add a new port type for AMD carrizo and set UART registers
and dma rx size as hardware requirement.
In the end, we make our IOMMU driver to support non-pci device, so
UART DMA really works.

Thanks,
Hongcheng
