With phy-reset-gpios are enabled for i.MX8MM-EVK board, phy
will be reset. Without CONFIG_AT803X_PHY as y, board will stop
booting in NFS DHCP, because phy is not ready. So mark
CONFIG_AT803X_PHY from m to y to make board boot when using nfs rootfs.

Hello Peng,

this patch broke my imx8qm nfs setup. With the generic phy driver my
board is booting fine. But with the AT803X_PHY=y enabled  I'am running
into the following phy issue. So on my side it looks inverse as on
yours. What is the best proposal to fix this?

Which DTS are you using?

I bet one dollar that 6d4cd041f0af triggered a latent bug in the DTS.

I'am using this DTS which I'am currently working on:

So what should I fix in my device tree?

Some suggestions you could try:

- Try to use phy-mode = "rgmii-id"; instead,
- The PHY address 0 does not match the reg value of 4, so you need to
double check the PHY address and make the @ and reg values to match.
- If you have a GPIO connected to the Ethernet PHY reset pin, then you
should describe it in the dts and also provide a delay as per the
AR803X datasheet.

In the board DTS I used to work on, I had this:

&eth0 {
	phy-connection-type = "rgmii-id";
	phy-handle = <&eth0_phy>;
	#address-cells = <1>;
	#size-cells = <0>;

	/* Atheros AR8035 */
	eth0_phy: ethernet-phy@4 {
		compatible = "ethernet-phy-id004d.d072",
			     "ethernet-phy-ieee802.3-c22";
		interrupts = <37 IRQ_TYPE_EDGE_RISING>;
		reg = <4>;
	};
};

In your DTS, you #include "imx8qm.dtsi"
I found no such file:
$ git ls-files | grep imx8qm
drivers/pinctrl/freescale/pinctrl-imx8qm.c
include/dt-bindings/pinctrl/pads-imx8qm.h

In your patch:
https://patchwork.kernel.org/patch/11211567/

+&fec1 {
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_fec1>;
+	phy-mode = "rgmii-txid";
+	phy-handle = <&ethphy0>;
+	fsl,magic-packet;
+	fsl,rgmii_rxc_dly;
+	status = "okay";
+
+	mdio {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		ethphy0: ethernet-phy@0 {
+			compatible = "ethernet-phy-ieee802.3-c22";
+			reg = <4>;
+			at803x,eee-disabled;
+			at803x,vddio-1p8v;
+		};
+	};
+};

Try all possible 'phy-mode' (rgmii, rgmii-id, rgmii-rxid, rgmii-txid)
Investigate 'fsl,rgmii_rxc_dly' (it's not a standard Linux DT prop)
Documentation/devicetree/bindings/net/ethernet-controller.yaml

ok I fix that in my dts.

it seems that currently no ethernet phy reset gpio is connected on that
advantech eval board. The vendor says there is a optional resistor which can
be mounted.

So you are saying your Atheros 8035 device works with generic phy
driver but not with AT803X_PHY driver?  That makes no sense.  Did you
add phy-reset-gpios property for your device?
