[PATCH v2 3/5] ARM: dts: imx6qdl-sr-som: add support for alternate phy addresses

[sbabic@denx.de]

> The Cubox has an unstable phy address - which can appear at either
> address 0 (intended) or 4 (unintended).
> SoM revision 1.9 has replaced the ar8035 phy with an adin1300, which
> will always appear at address 1.
> Change the reg property of the phy node to the magic value 0xffffffff,
> which indicates to the generic phy driver that all addresses should be
> probed. That allows the same node (which is pinned by phy-handle) to match
> either the AR8035 PHY at both possible addresses, as well as the new one
> at address 1.
> Also add the new adi,phy-output-clock property for enabling the 125MHz
> clock used by the fec ethernet controller, as submitted to Linux [1].
> Linux solves this problem differently:
> For the ar8035 phy it will probe both phy nodes in device-tree in order,
> and use the one that succeeds. For the new adin1300 it expects U-Boot to
> patch the status field in the DTB before booting
> While at it also sync the reset-delay with the upstream Linux dtb.
