Use devm_platform_ioremap_resource() to simplify the code a bit.
This is detected by coccinelle.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);
if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
statement (manually).

The Tegra EQOS driver already resets the MDIO bus at probe time via the
reset GPIO specified in the phy-reset-gpios device tree property. There
is no need to reset the bus again later on.
This avoids the need to query the device tree for the snps,reset GPIO,
which is not part of the Tegra EQOS device tree bindings. This quiesces
an error message from the generic bus reset code if it doesn't find the
snps,reset related delays.

If the subdriver defers probe, do not show an error message. It's
perfectly fine for this error to occur since the driver will get another
chance to probe after some time and will usually succeed after all of
the resources that it requires have been registered.

According to DT bindings documentation we are expecting a
property called "snps,read-requests" but we are parsing
instead a property called "read,read-requests".
This is clearly a typo. Fix it.

The NVIDIA Tegra186 SoC contains an instance of the Synopsys DWC
ethernet QOS IP core. The binding that it uses is slightly different
from existing ones because of the integration (clocks, resets, ...).

Split out the binding specific parts of ->probe() and ->remove() to
enable the driver to support variants of the binding. This is useful in
order to keep backwards-compatibility while making it easy for a sub-
driver to deal only with the updated bindings rather than having to add
compatibility quirks all over the place.

This patch adds a new glue driver called dwmac-dwc-qos-eth which
was based in the dwc_eth_qos as is. To assure retro-compatibility a slight
tweak was also added to stmmac_platform.
