This adds an SMP boot method for the ARM RealView reference
designs. We also select HAVE_SMP by default and make it use
SMP_ON_UP so we only need to support one single kernel across
the RealView reference designs when using DT.
The RealViews need to have the SCU (Snoop Control Unit)
activated on boot, and this is now done by looking up its
address from the device tree and initializing it and counting
the available cores.
The RealViews boot by using a magic address register in the
system controller (SYS_FLAGS) to store the boot address,
the ROM will then read this register to the PC when the CPUs
are taken out of WFI. This code uses a handle to the syscon
regmap to access this register.

With device tree it is no more possible to reset the PHY at board
level. Furthermore, doing in the driver allow to power down the PHY when
the network interface is no more used.
This reset can't be done at the PHY driver level. The PHY must be able to
answer the to the mii bus scan to let the kernel creating a PHY device.
The patch introduces a new optional property "phy-reset-gpios" inspired
from the one use for the FEC.

- Support runtime pm
. In case of most ARM SoC, each IP has each power domain which should be
controlled by each IP driver using runtime pm interface. So this patch
series makes each IP driver to control its own power domain when
drm dpms is requested.
- Support of_graph based dt binding for DP panel.
. This patch series adds of_graph based dt binding for DP panel.
And also it keeps backward compatibility. This includes dt binding
patch so I got Acked-by from Krzysztof Kozlowski who is a Exynos
SoC maintainer and from Rob Herring who is a device tree maintainer.
- Cleanup for Exynos DRM IPP enhancement.
. This patch series is a first step for enhancing existing IPP framework
which will integrate existing IPP functions with DRM KMS part so that
these can be transparent to userspace. For other portion of the patch
series, we will have more times for the review.]

In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compatibility strings has been adopted.
Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas USB DMA Controller driver to follow this convention.
