Merge tag 'dt-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2013-05-07T18:06:17+00:00

Pull ARM SoC device tree updates (part 2) from Arnd Bergmann:
 "These are mostly new device tree bindings for existing drivers, as
  well as changes to the device tree source files to add support for
  those devices, and a couple of new boards, most notably Samsung's
  Exynos5 based Chromebook.

  The changes depend on earlier platform specific updates and touch the
  usual platforms: omap, exynos, tegra, mxs, mvebu and davinci."

serial: mxs-auart: move to use generic DMA helper

2013-04-04T13:22:45+00:00

With the generic DMA device tree helper supported by mxs-dma driver,
client devices only need to call dma_request_slave_channel() for
requesting a DMA channel from dmaengine.

serial: of_serial: Handle auto-flow-control property

2013-03-25T23:36:48+00:00

Automatic Flow Control capability is not tied to this
property. This is only one way of detecting it. The property
is limited to be used only with 8250 driver.

serial: of_serial: Handle fifo-size property

2013-03-25T21:06:44+00:00

This will reduce the need for extra types in 8250.c just
in case the fifo size differs from the standard.

serial/efm32: parse location property

2013-01-21T21:56:46+00:00

The non-dt probing allowed passing the location via platform data from
the beginning. So make up leeway for device tree probing.

serial/arc-uart: switch to devicetree based probing

2013-01-16T06:16:05+00:00

* DT binding for arc-uart
* With alll the bits in place we can now use DT probing.

Note that there's a bit of kludge right now because earlyprintk portion
of driver can't use the DT infrastrcuture to get resoures/plat_data.
This requires some infrastructre changes to of_flat_ framework

serial: mxs-auart: add the DMA support for mx28

2012-11-16T12:42:46+00:00

Only we meet the following conditions, we can enable the DMA support for
auart:

  (1) We enable the DMA support in the dts file, such as
      arch/arm/boot/dts/imx28.dtsi.

  (2) We enable the hardware flow control.

  (3) We use the mx28, not the mx23. Due to hardware bug(see errata: 2836),
      we can not add the DMA support to mx23.
