From: Frieder Schrempf <frieder at fris.de>

Hi Frieder,

> Previously we falsely relied on the PHY driver to unconditionally
> enable the internal RX delay. Since the following fix for the PHY
> driver this is not the case anymore:
>
> commit 7b005a1742be ("net: phy: mscc: configure both RX and TX internal
> delays for RGMII")
>
> In order to enable the delay we need to set the connection type to
> "rgmii-rxid".
>
> Fixes: 21c4f45b335f ("arm64: dts: Add the Kontron i.MX8M Mini SoMs and baseboards")
> Cc: stable at vger.kernel.org
> Signed-off-by: Frieder Schrempf <frieder.schrempf at kontron.de>
