[PATCH v1 00/12] serial: 8250: split LPSS to 8250_lpss, enable DMA on Quark

From: Andy Shevchenko

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 series [1] that is now under review.

That's why I ask Vinod to create immutable tag / branch for the [1] and the
dependants (at least one more, which is sata_dwc_460ex).
