[PATCH 0/6] 8250: AMD Carrizo UART PL300 DMA enablement

[Wang Hongcheng]

Hi, all

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

V1:
http://lkml.kernel.org/g/1449199466-6081-1-git-send-email-annie.wang@xxxxxxx

Major changes from V1->V2:
- Create an amba device in driver/acpi/acpi_apd.c, as the DMA device
  relies on UART device and it can only be used by UART device, they
  are not siblings. UART device should be the parent of DMA device.
- base_request_line and num are added to acpi dma controller register

Thanks,
Hongcheng (Annie)

Wang Hongcheng (6):
  8250/Kconfig: add config option CONFIG_SERIAL_8250_AMD
  ACPI: create setup_quirk in acpi_apd
  ACPI: add 2 parameters to function acpi dma controller register
  dmaengine: pl330: add new items for pl330 private data
  dmaengine: pl330: provide ACPI dmaengine interface
  Serial:8250: New Port Type PORT_AMD_8250
