Instead of probing you specify the devices on the i2c-bus in the dts. Examp=
le
for the pcm032 looks like this (from the kernel-tree):

i2c@3d40 {
	#address-cells =3D <1>;
	#size-cells =3D <0>;
	compatible =3D "fsl,mpc5200b-i2c","fsl,mpc5200-i2c","fsl-i2c";
	reg =3D <0x3d40 0x40>;
	interrupts =3D <2 16 0>;
	fsl5200-clocking;

	rtc@51 {
		compatible =3D "nxp,pcf8563";
		reg =3D <0x51>;
	};
	eeprom@52 {
		compatible =3D "at24,24c32";
		reg =3D <0x52>;
	};
};

Boards which relied on probing need to have such child nodes added.
