DP83867 ethernet PHY regression

[Francesco Dolcini <francesco@dolcini.it>]

Hello all,
commit da9ef50f545f ("net: phy: dp83867: perform soft reset and retain
established link") introduces a regression on my TI AM62 based board.

I have a working DTS with Linux TI 5.10 downstream kernel branch, while
testing the DTS with v6.4-rc in preparation of sending it to the mailing
list I noticed that ethernet is working only on a cold poweron.

With da9ef50f545f reverted it always works.

Here the DTS snippet for reference:

&cpsw_port1 {
	phy-handle = <&cpsw3g_phy0>;
	phy-mode = "rgmii-rxid";
};

&cpsw3g_mdio {
	assigned-clocks = <&k3_clks 157 20>;
	assigned-clock-parents = <&k3_clks 157 22>;
	assigned-clock-rates = <25000000>;

	cpsw3g_phy0: ethernet-phy@0 {
		compatible = "ethernet-phy-id2000.a231";
		reg = <0>;
		interrupt-parent = <&main_gpio0>;
		interrupts = <25 IRQ_TYPE_EDGE_FALLING>;
		reset-gpios = <&main_gpio0 17 GPIO_ACTIVE_LOW>;
		reset-assert-us = <10>;
		reset-deassert-us = <1000>;
		ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
		ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
	};
};

Any suggestion?
Francesco
