[PATCH] ARM: imx: Increase PHY auto-negotiation timeout to 20s on MX8Menlo

[PATCH] ARM: imx: Increase PHY auto-negotiation timeout to 20s on MX8Menlo

[Marek Vasut]

The ethernet PHY on MX8Menlo board takes a while to come out of
reset, increase the auto-negotiation timeout to prevent it from
timing out in case the ethernet is used right after the board was
reset.

Is this specific of MX8Menlo or something we should have on
verdin-imx8mm instead? I am not aware of any report on this issue on the
verdin, on the other hand the verdin imx8mm has normally only one
ethernet interface, and this is the one from the verdin SOM.

This is specific to this particular carrier board and does not apply to 
Dahlia board or Verdin SoM.

Applied, thanks.
