Subject: [PATCH 0/2] ARM: dts: am335x-evm/evmsk: Fix PHY mode for ethernet

Hi,

cd28d1d6e52e: ("net: phy: at803x: Disable phy delay for RGMII mode") broke the
ethernet networking on evmsk (and most likely on the evm as well):
https://patchwork.ozlabs.org/patch/1028527/

v1 patch to fix the situation:
https://patchwork.ozlabs.org/patch/1040617/

It turned out that the at803x driver is actually broken and need to be fixed
along with the DT data.

The following series is proposed to fix the driver:
https://patchwork.ozlabs.org/project/netdev/list/?series=92611

but the PHT mode needs to be switched to rgmii-id from rgmii-txid:
The rx delay is enabled by default and the driver never disabled it so when
asking rgmii-txid it actually got rgmii-id.

The patch can be backported to stable, I have tested that it is not causing
regression with the old, broken driver.

Regards,
Peter
