Remove pullup on dbgu DTXD signal, it is a push-pull output thus the
pullup is pointless.
Add pullup on dbgu DRXD signal, it prevents the DRXD signal to be left
floating and so consuming a useless extra amount of power in crowbarred
state if nothing is externally connected to dbgu.

The PMC is not only used to drive the clocks but also has some registers
related to other functions. One of those is for example the USB gadget
bias.
Using a syscon allows to properly separate those functions.

Pull ARM DT updates from Olof Johansson:
"As always, this tends to be one of our bigger branches. There are
lots of updates this release, but not that many jumps out as something
that needs more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- more graphics DT pieces falling into place on Exynos, bridges,
clocks.
- plenty of DT updates for Qualcomm platforms for various IP blocks
- some churn on Tegra due to switch-over to tool-generated pinctrl
data
- misc fixes and updates for Atmel at91 platforms
- various DT updates to add IP block support on Broadcom's Cygnus
platforms
- more updates for Renesas platforms as DT support is added for
various IP blocks (IPMMU, display, audio, etc)"

Pull ARM SoC late cleanups from Arnd Bergmann:
"These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle. We
normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time we
need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc
cleanup series because of interdependencies with timer drivers now
moved out of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes for
Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10."

Fix the use of USART on both at91sam9x5 and at91sam9n12. In DTS, the
atmel,use-dma-[rx|tx] property is present but a DMA channel cannot be used.
Indeed the connexion between the DMA engine and the slave is not implemented
yet in Device Tree.
Note however that this property is also used for PDC (private DMA) on older
SoCs. This is why the driver alone cannot determine the validity of this
property.
