net: fec_imx: Add devicetree support for mdio bus ...

The fec has a mdio bus. This adds support for a subnode
in which the phys on this bus can be specified.

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: phy: genphy: always write MII_CTRL1000 when available ...

the phydev->supported field does not necessarily match the hardware
capabilities, it could be limited by the board to force the phy
to a lower speed. In this case make sure the gigabit advertise bits
are cleared on a gigabit phy.

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.

usb: chipidea i.MX: relax phy_type requirements ...

the type is not specified in the devicetree in this case.

of: Drop devicetree merge support ...

I assume I am the only person knowing that barebox is able to
merge devicetrees. This feature seems broken for a while now since
trying to merge devicetress results in:

unflatten: too many end nodes

Remove this feature to save the complexity.

net: phy: Support finding a phy in the devicetree ...

When the ethernet device has a device_node then try finding
the associated phy via the phy-handle property.

This makes the phy handling via devicetree transparent to the
ethernet drivers.

net: phy: move setting of phy_map to phy_register_device ...

The phy_map should be valid once a phy_device is registered. This

net: phy: factor out phy_device_attach function ...

phy_device_connect combines searching for a phy with actually attaching

have a function for each purpose. This makes the logic of phy_device_connect
simpler.

mtd: nand: mxs: Fix 2k nand with oob size of 224 bytes ...

The mxs nand driver has a calculation for the ecc strength.
This calculation was not used for some common nands and it
was assumed that 2k page nands always have a ecc strength
of 8. This is not true since there are devices with 224 bytes
of oob instread of 64 bytes. These allow for a greater ecc
strength. Since the kernel relies on the calculation and
we have to be consistent with the kernel use the calculcation
in barebox aswell and just remove our assumptions.

mfd: mc13xxx: Allow to set callback for mc13xxx ...

Some boards have to initialize the PMIC before other devices can
be initialized. This requires three levels of initcalls: one level
in which the PMIC is probed, one in which the board can call mc13xxx_get()
and the third one to initialize the PMIC dependent devices.

Allow to register a callback which is called once the PMIC is initialized.
This way mc13xxx_get() is no longer necessary and the number of required
initcalls levels is reduced to two.
