Actually, this one might be causing a regression, since it conflicts
with a fix that's in mainline now:

commit b8659752c37ec157ee254cff443b1c9d523aea22
Refs: v3.19-rc1-4-gb8659752c37e

    ARM: at91: board-dt-sama5: add phy_fixup to override NAND_Tree

    Appearance: On some SAMA5D4EK boards, after power up, the Eth1 doesn't work.

    Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081,
    But it outputs LOW during the reset period, which cause the
NAND_Tree# enabled.

    Add phy_fixup() to disable NAND_Tree by overriding the Operation
    Mode Strap Override register(i.e. Register 16h) to clear the NAND_Tree bit.

    Signed-off-by: Nicolas Ferre <nicolas.ferre@...el.com>


This conflicts since it changes board-dt-sama5.c which is removed by
this branch, but I don't see the same fixup in your branch.

I've dropped this branch so that you can address the above without
causing a bisectability issue -- please send fresh pull request when
addressed.
