Merge tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2014-08-08T18:16:58+00:00

Pull ARM SoC device-tree changes from Olof Johansson:
 "Unlike the board branch, this keeps having large sets of changes for
  every release, but that's quite expected and is so far working well.

  Most of this is plumbing for various device bindings and new
  platforms, but there's also a bit of cleanup and code removal for
  things that are moved from platform code to DT contents (some OMAP
  clock code in particular).

  There's also a pinctrl driver for tegra here (appropriately acked),
  that's introduced this way to make it more bisectable.

  I'm happy to say that there were no conflicts at all with this branch
  this release, which means that changes are flowing through our tree as
  expected instead of merged through driver maintainers (or at least not
  done with conflicts).

  There are several new boards added, and a couple of SoCs.  In no
  particular order:

   - Rockchip RK3288 SoC support, including DTS for a dev board that
     they have seeded with some community developers.
   - Better support for Hardkernel Exynos4-based ODROID boards.
   - CCF conversions (and dtsi contents) for several Renesas platforms.
   - Gumstix Pepper (TI AM335x) board support
   - TI eval board support for AM437x
   - Allwinner A23 SoC, very similar to existing ones which mostly has
     resulted in DT changes for support.  Also includes support for an
     Ippo tablet with the chipset.
   - Allwinner A31 Hummingbird board support, not to be confused with
     the SolidRun i.MX-based Hummingboard.
   - Tegra30 Apalis board support"

serial: 8250_dw: Add optional reset control support

2014-07-27T18:07:07+00:00

The Allwinner A31 and A23 SoCs have a reset controller
maintaining the UART in reset by default.

This patch adds optional reset support to the driver.

serial: samsung: get fifosize via device tree

2014-07-18T01:18:22+00:00

UART modules on some SoCs only differ in the fifosize of each
UART channel. Its useless to duplicate the drv_data structure
or create a compatible name for such a change.

We can get fifosize via the device tree nodes (not mandating it).

Also updates the documentation.

serial: efm32: correct namespacing of location property

2014-07-12T00:49:46+00:00

Olof Johansson pointed out that usually the company name is picked as
namespace prefix to specific properties. So expect "energymicro,location"
but fall back to the previously introduced name "efm32,location".

Simply document new compat strings.
There appears to be no need for a driver updates.

2014-07-10T22:27:37+00:00

First try to find the named clock variants then fall back to the already
existing handling of a nameless declared baudclk.

This also adds the missing documentation for this already existing variant.

Documentation: devicetree: Update samsung UART bindings

2014-07-10T00:22:55+00:00

The primary purpose of this patch is to add information about (now
required) aliases of UART ports. However the documentation currently is
heavily outdated and so this patch also takes care of this.
