The Synopsys stmmac fifo sizes are configurable, and need to be known
in order to configure certain controller features. This patch adds
tx-fifo-depth and rx-fifo-depth properties to the stmmac document
file.

The DWMAC block on certain SoCs (such as IMG Pistachio) have a second
clock which must be enabled in order to access the peripheral's
register interface, so add support for requesting and enabling an
optional "pclk".

The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).
The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.
If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.
Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.

This change adds bindings for the number of multicast hash bins and perfect
filter entries supported by the Synopsys EMAC. The Synopsys EMAC core is
configurable at device creation time, and can be configured for a different
number of multicast hash bins and a different number of perfect filter
entries. The device does not provide a way to query these parameters,
therefore parameters are required. The Altera Cyclone V SOC has support for
256 multicast hash bins and 128 perfect filter entries, and is different
than what's currently provided in the stmmac driver.

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

This patch is an attempt to gather the Ethernet related bindings in one file,
like it's done in the MMC and some other subsystems. It should save some of
the trouble of documenting several properties over and over in each binding
document, instead only making reference to the main file.
I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR)
standard as a base for the properties description, also documenting some ad-hoc
properties that have been introduced over time despite having direct analogs in
ePAPR.

This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

The snps,phy-addr device tree property is non-standard, and should be
removed in favor of proper phy node support. Remove it from the binding
documents and warn if the property is still used.
Most PHYs respond to address 0, but a few don't, so auto-detect PHY
address by default, to make up for the lack of explicit address selection.

This patch adds phy reset callback support for stmmac driver via device

define the reset signal via gpio.
With this patch users can conveniently pass reset gpio number with pre,
pulse and post delay in micro secs via DTs.
