ASIX AX88772B started to pack data even more tightly. Packets and the ASIX packet
header may now cross URB boundaries. To handle this we have to introduce
some state between individual calls to asix_rx_fixup().

- Remove OFDEVICE dependency from PINCTRL. It won't do
much then, so add a comment to Kconfig when PINCTRL is
selected without OFDEVICE
- Let Architectures only select PINCTRL instead of the
particular driver. Change the drivers to 'default y if $SOC'
to make sure the drivers are still compiled if the corresponding
SoC is selected
This fixes Kconfig warnings like:
warning: (PINCTRL_ARMADA_370 && PINCTRL_ARMADA_XP && PINCTRL_DOVE && PINCTRL_KIRKWOOD) selects PINCTRL which has unmet direct dependencies (OFDEVICE)

The driver contains the gpio and pinctrl parts (like in linux) because the two parts

The current fixup code is slightly wrong, and only works when the
root address cell number is one.
However, Armada XP has a root address cell number of two. In this case
we are currently applying the fixup on the child high base address,
while it should be applied on the child low base address.
Fix it and add some detailed explanation to avoid having to figure this
out each time.

Ported from linux-3.15.
The most notable barebox driver version changes:

* drop "allwinner,sun*" stuff;
* drop message offloading support;
* add reg-io-width devicetree parameter to use driver

net: phy: add minimal support for QSGMII PHY
This commit adds the necessary definitions for the PHY layer to
recognize "qsgmii" as a valid PHY interface. A QSMII interface, as
defined at
http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface,
is "is a method of combining four SGMII lines into a 5Gbit/s
interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX
data and a single LVDS clock signal. QSGMII uses significantly fewer
signal lines than four SGMII busses."
This type of MAC <-> PHY connection might require special handling on
the MAC driver side, so it should be possible to express this type of
MAC <-> PHY connection, for example in the Device Tree.

This property is wrongly documented as 'optional', although all the
