One question about 8250 UART driver

[Yong Wang]

Hi all,

We have a PCI based UART controller that is compatible with the existing
8250 serial driver in most aspects. However, one exception is that our
UART controller can take advantage of the onboard DMA contoller to
achieve higher throughput. Could you please share your insights about
what is the proper way to add such DMA support into existing 8250 driver?

Thanks
-Yong
