Subject: [PATCH 0/6] 8250: AMD Carrizo UART PL300 DMA enablement
Date: Mon, 4 Jan 2016 13:31:35 +0800 [thread overview]
Message-ID: <1451885501-2710-1-git-send-email-annie.wang@amd.com> (raw)
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@amd.com
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)

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
