08344f3b43 ARM: SoC: late DT updates for v4.7
This is a collection of a few late fixes and other misc. stuff that
 had dependencies on things being merged from other trees.
 
 The Renesas R-Car power domain handling, and the Nvidia Tegra USB
 support both hand notable changes that required changing the DT binding
 in a way that only provides compatibility with old DT blobs on new
 kernels but not vice versa. As a consequence, the DT changes
 are based on top of the driver changes and are now in this branch.
 
 For NXP i.MX and Samsung Exynos, the changes in here depend on
 other changes that got merged through the clk maintainer tree.

6d20b24a2b ARM: dts: vf-colibri: increase NAND clock speed
The NAND flash memory populated on Colibri VF61 allows faster NAND
timings than the flash memory on VF50. Additionally, due to divider
limitations, VF61 did clock the flash even slower than VF50. Assign
the NFC clock in the module specific device trees vf500-colibri.dtsi
and vf610-colibri.dtsi respectively.

This increases raw read speed on Colibri VF61 by about 20%.

9b1a1779e9 ARM: dts: vf-colibri: alias the primary FEC as ethernet0
The Vybrid based Colibri modules provide a on-module PHY which is
connected to the second FEC instance FEC1. Since the on-module
Ethernet port is considered as primary ethernet interface, alias
fec1 as ethernet0. This also makes sure that the first MAC address
provided by the boot loader gets assigned to the FEC instance used
for the on-module PHY.

47b06e6ef5 ARM: dts: vf-colibri: add basic supply regulators
Colibri modules need to be powered using the power pins 3V3 and
AVDD_AUDIO. Add fixed regulators which represent this power rails.
Potentially, those power rails could be switched on a carrier
board. A carrier board device tree could add a own regulator with
a GPIO, and reference that regulator in a vin-supply property of
those new module level system regulators.

5c35b778bf ARM: dts: vf-colibri: assign Ethernet clock explicitly
Assign Ethernet clock parents explicitly. The Colibri VF61
uses the 50MHz Ethernet clock provided by PLL5.

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.

GPLv2-only devicetrees make reuse difficult for software components
licensed under a different license.

The consensus is that a GPL/X11 dual-license should allow all necessary
uses, so relicense the vf*colibri* files to this combination.
