DP83867IRRGZT Ethernet DT configuration in stm32mp257f-ev1

[sanjaysb]

The below device tree is for RTL8211F-CG, but i needed help with configuring DT for DP83867IRRGZT, which DT binding should i refer, and if possibly have a DT configured for DP83867IRRGZT, do share it.

Hoping for a quick reply,

Thanks in advance.

&eth1 {
	status = "disabled";
	pinctrl-0 = <&eth1_rgmii_pins_a &eth1_mdio_pins_a>;
	pinctrl-1 = <&eth1_rgmii_sleep_pins_a &eth1_mdio_sleep_pins_a>;
	pinctrl-names = "default", "sleep";
	phy-mode = "rgmii-id";
	max-speed = <1000>;
	phy-handle = <&phy1_eth1>;
	st,eth-clk-sel;
	snps,ext-systime;

	mdio1 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "snps,dwmac-mdio";
		phy1_eth1: ethernet-phy@4 {
			compatible = "ethernet-phy-id001c.c916";
			reset-gpios =  <&gpioj 9 GPIO_ACTIVE_LOW>;
			reset-assert-us = <10000>;
			reset-deassert-us = <80000>;
			realtek,eee-disable;
			reg = <4>;
		};
	};
};

FYI, im working on a custom board with stm32mp257fai3 chip with custom ethernet

Hi @sanjaysb 

Did you check wiki documentation starting from Ethernet overview - stm32mpu 

It might gives you useful information.
