Cover letter [PATCH 0/3] ARM: dts: omap: workarounds for Ethernet PHY strap on DRA71 and DRA72 EVMs

Hi Tony,

Here are some patches to overcome incorrect Ethernet PHY strap settings on DRA72x EVM Rev C and DRA71 EVM. Both of these boards use TI's DP83867 PHY.

The incorrect PHY strap settings cause a voilation of PHY specification and need to be worked around in software as documented in the commit messages. But there is no known issue that these patches fix.

I did verify that there are no regressions with NFS boot on these boards after the patches are applied on v4.12-rc4.

The series itself has been rebased on your omap-for-v4.13/dt branch since it has some conflicts with patches you have queued.
