c895ef4650 net: Add MT7628 ethernet driver
This patch adds ethernet support for the MIPS based Mediatek MT76xx SoCs
(e.g. MT7628 and MT7688), including a minimum setup of the integrated
switch. This driver is loosly based on the driver version included in
this MediaTek github repository:

https://github.com/MediaTek-Labs/linkit-smart-uboot.git

Tested on the MT7688 LinkIt smart-gateway and on the
Gardena-smart-gateway.

0f347a0096 net: phy: ti: Add binding for the CLK_OUT pin muxing
The DP83867 has a muxing option for the CLK_OUT pin. It is possible
to set CLK_OUT for different channels.
Create a binding to select a specific clock for CLK_OUT pin.

Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for
the CLK_OUT pin muxing option") of mainline linux kernel.

fba725f410 net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driver
This patch adds support for enabling or disabling the lane swapping
(called "port mirroring" in PHY's CFG4 register) feature of the DP83867
TI's PHY device.

One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).

Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping
support in the DP83867 TI's PHY driver") of mainline linux kernel.

db40c1aa1c drivers/net/phy: add fixed-phy / fixed-link support
This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).

For this purpose we introduce a new phy-driver, called "Fixed PHY".

Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.

Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).

During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.

afb970f78a dt: net: add DWC EQoS binding
The Synopsys DWC EQoS is a configurable Ethernet MAC/DMA IP block which
supports multiple options for bus type, clocking and reset structure, and
feature list.

This patch imports the binding from the Linux kernel, including my V3
patch to extend the binding to cover the Tegra186, which is applied for
next-20160912. So far, my changes have been acked by Lars Persson, the
original author of the binding.

The original document was from:
[commit 4b405efbe12de28b26289282b431323d73992381 from the Linux kernel]

This takes the original document and adds a clarification on how the skew
values are represented in the code.
