[PATCH 0/4] mv643xx_eth device tree bindings

[PATCH 0/4] mv643xx_eth device tree bindings

[Florian Fainelli]

Hi all,

This patch serie implements mv643xx_eth device tree bindings. I opted for
the reuse of the bindings already defined in
Documentation/devicetree/bindings/marvell.txt so that we do not create
any confusion.

For reference, I have included the mv643xx-eth related nodes in the
corresponding Kirkwood, Dove and Orion5x .dtsi files so you can more
easily test on your own platforms.

I tested these on a custom 88F6181-based boards, but I would appreciate
more testing.

Thanks!

[PATCH 1/4] mv643xx_eth: add Device Tree bindings

[Florian Fainelli]

This patch adds Device Tree bindings following the already defined
bindings at Documentation/devicetree/bindings/marvell.txt. The binding
documentation is also enhanced with new optionnal properties required
for supporting certain devices (RX/TX queue and SRAM). Since we now have
proper support for the orion MDIO bus driver, there is no need to fiddle
around with device tree phandles.

This breaks on non-OF builds, I will wait for more comments to show up

[PATCH 2/4] ARM: kirkwood: add device node entries for the gigabit interfaces

[Florian Fainelli]

This patch modifies kirkwood.dtsi to specify the various gigabit
interfaces nodes available on kirkwood devices. They are disabled by
default and should be enabled on a per-board basis. egiga0 and egiga1
aliases are defined for convenience. The mdio node is also present and
should be enabled on a per-board basis as well.

Your first patch is going to go through David's tree, and I'd like to
prevent any hard dependency between his tree and arm-soc.  Can this
change be pulled out and applied separately?  At first glance, it looks
like a fix to match sata and pcie.

thx,

Jason.

I just actually did the same thing as what SATA has (two clocks with 
names), define a clock name "0" and "1" (is not that too generic BTW?) 
for ge0 and ge1. But I don't think this change is required.

[PATCH 3/4] ARM: orion5x: add gigabit ethernet device tree node

[Florian Fainelli]

This patch adds the gigabit ethernet device tree node to orion5x.dtsi.
This node is disabled by default and must be enabled on a per-board
basis. For completeness and easier testing the MDIO node is also added
and disabled by default.

[Florian Fainelli]

This patch adds the gigabit ethernet device tree nodes to dove.dtsi in a
disabled state. The gigabit ethernet device tree node must be enabled on
a per-board basis. For completeness and easier testing the MDIO node is
