DP83822 phy not able to attach (LS1021A) SDK2.0

[winstonjacob]

I am working with LS1021A processor custom board Ethernet configuration, DP83822 phy is used. and here I mentioned my kernel DTS entries. And I attached log and dp83822.c driver which I used in kernel.But the phy is not detected in kernel. I am getting the log like this. Please help me to resolve this issue.

net eth0: could not attach to PHY

net eth1: could not attach to PHY

Please put dp83822.c in folder drivers/net/phy/, and add the following in drivers/net/phy/Makefile.

obj-$(CONFIG_DP83822_PHY) += dp83822.o

Please enable CONFIG_DP83822_PHY in Linux Kernel configuration file(.config).

In the dts file, please modify compatible = "ethernet-phy-ieee802.3-c22" to compatible = "ti,dp83822", "ethernet-phy-ieee802.3-c22". Please make sure "phy address" is specified correctly in "reg" property.

rgmii_phy1: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22"; // compatible = "ti,dp83822", "ethernet-phy-ieee802.3-c22";

rx-internal-delay-ps = <1>;
tx-internal-delay-ps = <1>;
reg = <0x1>;   //phy address
};
