Assign Ethernet clock parents explicitly. The VF610 Tower Board
uses the external Ethernet clock input which is connected to
a 50MHz clock.
The Vybrid SoC has two ethernet interfaces (fec0 and fec1) which
use the same clock source (VF610_CLK_ENET). Therefore this parent
configuration affects multiple consumer devices and need to be
specified in the clock provider node.

Downstream packages like Debian flash-kernel use
/proc/device-tree/model
to determine which dtb file to install.
Hence each dts in the Linux kernel should provide a unique model
identifier.
Commit 8536239e37 ("ARM: dts: Restructure imx6qdl-wandboard.dtsi for new
rev C1 board.")' created new files imx6dl-wandboard-revb1.dts and
imx6q-wandboard-revb1.dts but used the same model identifier as in
imx6dl-wandboard.dts and imx6q-wandboard.dts.
This patch provides unique model identifiers for revision B1 of
the Wandboard Dual and Wandbaord Quad.
The patch leaves imx6dl-wandboard.dts and imx6q-wandboard.dts unchanged
because it is not foreseeable if the same dts will valid for future
board revisions or not. Furthermore we should avoid unnecessary
changes.

The i.MX6Quad Plus processor is an high performance SOC of i.MX6 family.
It has enhanced graphics performance and increased overall memory bandwidth
compared to i.MX6Q. Most of the design are same as i.MX6Quad/Dual, so code
for i.MX6Quad can be resued by this chip. The revision number is identied as
i.MX6Q Rev2.0, but actually it is a new chip, as we did many change to the
overall architecture.
This patch adds basic dtsi file support for the new i.MX6Quad Plus processor.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.
The executive summary:
- ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
- Avoid useless rebuilds for zboot.
- jz4780: Add NEMC, BCH and NAND device tree nodes
- Initial support for the MicroChip's DT platform. As all the device
drivers are missing this is still of limited use.
- Some Loongson3 cleanups.
- The unavoidable whitespace polishing.
- Reduce clock skew when synchronizing the CPU cycle counters on CPU
startup.
- Add MIPS R6 fixes.
- Lots of cleanups across arch/mips as fallout from KVM.
- Lots of minor fixes and changes for IEEE 754-2008 support to the
FPU emulator / fp-assist software.
- Minor Ralink, BCM47xx and bcm963xx platform support improvments.
- Support SMP on BCM63168"

To allow the use of these definitions by KVM for decoding cache ops,
break the definitions down into parts where it makes sense to do so, and
add masks for the Cache and Op field within the cache op.
