Subject: [PATCH v4 00/11] serial: 8250: split LPSS to 8250_lpss, enable DMA on Quark
Date: Wed, 4 May 2016 17:32:22 +0300 [thread overview]
Message-ID: <1462372353-70128-1-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
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].

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
