UART modules can use DMA for offloading data transfers and reducing
interrupts, so enable this feature for Exynos5 boards. Tested on
Google ChromeBook Snow (Exynos5250), Odroid XU (Exynos5410) and Odroid
XU3 (Exynos5422) boards.

Fix invalid GIC interrupt flags - type IRQ_TYPE_NONE is not allowed for GIC
interrupts. Although this was working but with error messages like:
genirq: Setting trigger mode 0 for irq 16 failed
Use level high interrupt instead of type none. The choice of level high was
rather an arbitrary decision hoping it will work on each platform. Tests shown
no issues so far.

Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and
generates an error:
genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68)
The GIC requires shared interrupts to be edge rising or level high.
Platform declares support for both. Arbitrarily choose level high
everywhere hoping it will work on each platform.

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

* Allwinner A31 Hummingbird board support, not to be confused with the

* Tegra30 Apalis board support
