Subject: powerpc/85xx: MPC8572DS - Fix eTSEC is not available on core1 of AMP boot
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a2ec009b7544fdbf1c6b6d624ce0167556247370;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

powerpc/85xx: MPC8572DS - Fix eTSEC is not available on core1 of AMP boot

The issue log on core1 is:
root@mpc8572ds:~# ifconfig eth0 10.192.208.244
net eth0: could not attach to PHY
SIOCSIFFLAGS: No such device

To attach PHY node mdio@24520 should not be disabled in dts of core1.
Because all PHYs are controlled through this node as follows:

mdio@24520 {
	phy0: ethernet-phy@0 {
		interrupts = <10 1 0 0>;
		reg = <0x0>;
	};
	phy1: ethernet-phy@1 {
		interrupts = <10 1 0 0>;
		reg = <0x1>;
	};
	phy2: ethernet-phy@2 {
		interrupts = <10 1 0 0>;
		reg = <0x2>;
	};
	phy3: ethernet-phy@3 {
		interrupts = <10 1 0 0>;
		reg = <0x3>;
	};

	tbi0: tbi-phy@11 {
		reg = <0x11>;
		device_type = "tbi-phy";
	};
};
