net: phy: mdio-mvebu: Make the clock property required ...

This property is wrongly documented as 'optional', although all the
ethernet units need a clock to be enabled in order to access the MDIO
interface. For that reason, this commit makes the property a required
one and fails to probe the device, when a clock is not properly provided.

net: phy: Add fallbacks for the obsoletes phy DT properties ...

In addition to the standard 'phy-handle' devicetree property, the binding
specifies two properties, which are considered obsolete: 'phy' and 'phy-device'.
This commit adds support for them in of_mdio_find_phy().

sandbox: allow "make ARCH=sandbox allyesconfig" ...

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.

This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.

USB: introduce usb_interface/usb_configuration structs ...

Currently we have two conflicting definitions of struct usb_config_descriptor
and struct usb_interface_descriptor in the tree. This is because the USB code
uses additional fields in the structs for internal housekeeping. Add
struct usb_interface and struct struct usb_configuration with the housekeeping
data and embed the corresponding hardware structs into them. This frees the
way to use the definitions from ch9.h in the next step.

USB: Kconfig: introduce USB_HOST symbol ...

This renames USB to USB_HOST since this is what the symbol really
means. Introduce a USB symbol which is selected by both USB_GADGET
and USB_HOST. This gives us a symbol to let common USB code depend
on.

net: add ENC28J60 support ...

ENC28J60 is a stand-alone Ethernet controller with SPI Interface
and integrated 10BASE-T PHY.

This driver was ported from linux-3.15.

The most notable barebox driver version changes:
  * add device tree support;
  * drop netif_msg_*() debug level checking;
  * use IF_ENABLED for checking CONFIG_ENC28J60_WRITEVERIFY;
  * add mii_bus support.

net: orion: generate unique port device names ...

Marvell Orion ethernet IP originally is multi-port capable, but SoCs
using the IP usually have multiple single-port controllers built in.
Currently, orion-gbe driver registers each port device with a constant
name, which causes a name conflict with multiple controller instances.

This patch uniquifies port device name generation by prepending
controller's base register address to resolve the name conflict.

net: phy: genphy: Make it work with of_set_phy_supported ...

phys start with features initialized from the phy driver
and are eventually limited by of_set_phy_supported. This
does not work with the genphy driver which starts with
no features and overwrites phydev->supported with the
values read from hardware in config_init. This overwrites
the features adjusted by of_set_phy_supported.
To fix this let the genphy driver start with full features
which are then only limited in config_init, but never
extended.

net: orion-gbe: use transparent-to-driver of mdio functions ...

barebox can transparently handle phys specified in the devicetree.
Use this functionality in the orion-gbe driver. This requires:

- add a device to the orion-gbe ports. This has the port device_node
  attached and is set as the parent of the ethernet device so that
  the ethernet code finds the correct device_node
- In the mdio-mvebu driver attach the device_node of the mdio device
  to the miibus device so that the phy code finds the correct node
- call phy_device_connect instead of of_phy_device_connect.
