instance indexes are a NAK. You can use i2cN aliases if you must.

Why do you need it? To access OLB? If so, add cell args to the OLB 
phandle instead.

Why we do what we do: I2C controller must write a 2 bit value depending
on the bus speed. All I2C controllers write into the same register.

Which register?  Your devices do not share IO address space.

mobileye,olb is a prop with a phandle to a syscon. That syscon contains
the register we are interested in.

So exactly what Rob said... I don't understand why you have chosen to go
with alias.


Best regards,
Krzysztof
