This is combined series of two things: - split out the Intel LPSS specific driver from 8250_pci into 8250_lpss - enable DMA support on Intel Quark UART
The patch has been tested on few Intel SoCs / platforms.
This is targeting serial subsystem, thus it would be nice to get and Ack from Vinod first. Moreover, the series depends on [1] that is now under review.
That's why I asked Vinod to create immutable tag / branch for the [1] and the dependants (at least one more, which is sata_dwc_460ex).
The series can be reached in the branch located at [2].

Since v1: - address most of Peter's comments (mostly changelog to patch 8) - add tag to patch 5 - drop patch 6 from the series to be separately dealt with
