Subject: [PATCH 0/5] 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.

Mathieu Olivari (4):
  stmmac: add phy-handle support to the platform layer
  stmmac: add fixed-link device-tree support
  stmmac: add ipq806x glue layer
  net: stmmac: ipq806x: document device tree bindings
