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. In any case I would like to ask Bryan to do independent test. 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 in Vinod's slave-dma tree. 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) can use it. The series can be reached in the branch located at [2].
