Merge branch 'stmmac-IPQ806x'

Mathieu Olivari says:

====================
Add support for QCA IPQ806x Ethernet GMAC controller

This patch set adds support for the integrated Ethernet GMAC controller
on QCA IPQ806x SoC. This controller is based on a Gigabit Synopsys
DesignWare IP, already supported in the stmmac driver located in
drivers/net/ethernet/stmicro/stmmac.

This change is done as a follow-up to the following thread:
*http://www.spinics.net/lists/netdev/msg311265.html
While previous attempt was creating a new driver to drive this controller,
this new post leverages the existing stmmac driver by implementing the
SoC specific glue to it.

Aside from the pure stmmac glue layer, we have a couple of related
patches:
*IPQ806x NSS clock addition is cherry-picked and refreshed from the
 following thread: https://lkml.org/lkml/2014/8/6/390
*phy-handle and fixed-link support are also added in this change set so the
 driver can be fully functional on platforms using device-trees as well as
 ethernet switches.

V2:
 *Fix MODULE_LICENSE to "Dual BSD/GPL" as the dwmac-ipq806x.c is using
  ISC license.

* IPQ806x DWMAC Ethernet controller
The device inherits all the properties of the dwmac/stmmac devices
described in the file net/stmmac.txt with the following changes.
Required properties:
- compatible: should be "qcom,ipq806x-gmac" along with "snps,dwmac"
and any applicable more detailed version number
described in net/stmmac.txt
- qcom,nss-common: should contain a phandle to a syscon device mapping the
nss-common registers.
- qcom,qsgmii-csr: should contain a phandle to a syscon device mapping the
qsgmii-csr registers.
Example:
gmac: ethernet@37000000 {
device_type = "network";
compatible = "qcom,ipq806x-gmac";
reg = <0x37000000 0x200000>;
interrupts = <GIC_SPI 220 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "macirq";
qcom,nss-common = <&nss_common>;
qcom,qsgmii-csr = <&qsgmii_csr>;
clocks = <&gcc GMAC_CORE1_CLK>;
clock-names = "stmmaceth";
resets = <&gcc GMAC_CORE1_RESET>;
reset-names = "stmmaceth";
