Correct.

I have done the same thing for the i2c-ibm_iic.c driver. Jean, I think
you will like this. It gets rid of the index and the numbered drivers.
And the walking of the device tree is very clean because the dts knows
all the devices.

For example here is the relevant portion of the dts for the Warp:

IIC0: i2c@ef600700 {
compatible = "ibm,iic-440ep", "ibm,iic-440gp", "ibm,iic";
reg = <ef600700 14>;
interrupt-parent = <&UIC0>;
interrupts = <2 4>;
#address-cells = <1>;
#size-cells = <0>;

ad7414@4a {
compatible = "adi,ad7414";
reg = <4a>;
interrupts = <19 8>;
interrupt-parent = <&UIC0>;
};
};

It clearly shows that first i2c controller (IIC0) contains one ad7414 device at address 4A.

Cheers,
Sean
