Since commit 1b3047b5208a80 ("net: phy: realtek: add support for configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver has control over the RGMII RX delay and it is disabling it for RGMII_TXID. The LS1043ARDB uses two such PHYs in RGMII_ID mode but in the device tree the mode was described as "rgmii_txid". This issue was not apparent at the time as the PHY driver took the same action for RGMII_TXID and RGMII_ID back then but it became visible (RX no longer working) after the above patch. Changing the phy-connection-type to "rgmii-id" to address the issue. Fixes: bf02f2ffe59c ("arm64: dts: add LS1043A DPAA FMan support") Signed-off-by: Madalin Bucur Signed-off-by: David S.
