The UART on Quark SoC has an integrated DMA engine and Kean Ho (CC'd)
is working with support for it. The plan is to add completely separate
probe driver for the Quark UART. Dealing with the integrated DMA
engine is too much for a quirk in 8250_pci.c.

So we can take this now and when Kean Ho is ready he needs to
basically revert it, or you could already introduce the new probe
driver, 8250_quark.c, and Kean Ho can then add the DMA engine handling
later to it.

IMO we should add the 8250_quark.c already now.

Sounds great - is the 8250_quark.c code ready ?

If so then fantastic I agree with you.

If not then, lets do as you suggest Heikki and apply the simple patch above in the interim.


Best,
BOD
