Subject[PATCH v4 00/11] serial: 8250: split LPSS to 8250_lpss, enable DMA on Quark
Date
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].

[1] http://www.spinics.net/lists/kernel/msg2244475.html
[2] https://bitbucket.org/andy-shev/linux/branch/topic%2Fdw%2Fqrk

Since v3:
- rebase on top of recent tty-next branch (includes couple of new patches)
- add Reviewed-by tag from Bryan (hope we got an agreement that current
approach would be okay)

Since v2:
- add tags
- rebase on top of new version of [1]

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

Andy Shevchenko (11):
dmaengine: dw: keep copy of custom slave config in dwc
dmaengine: dw: provide probe(), remove() stubs for users
dmaengine: dw: set polarity of handshake interface
dmaengine: dw: override LLP support if asked in platform data
serial: 8250_dma: switch to new dmaengine_terminate_* API
serial: 8250_dma: adjust DMA address of the UART
serial: 8250: enable AFE on ports where FIFO is 16 bytes
serial: 8250_lpss: split LPSS driver to separate module
serial: 8250_lpss: move Quark code from PCI driver
serial: 8250_lpss: enable MSI for Intel Quark
serial: 8250_lpss: enable DMA on Intel Quark UART
