Some of the parts only do backlight, so drop the "-backlight" on those. 
And having a sub-node makes no sense in that case. Perhaps it should be 
2 binding documents separating the single function devices and MFDs. The 
binding doc(s) doesn't have to align with the driver(s). You can have 1 
driver serve 2 bindings.

Yes, there is LM3532 and LM3695, which is backlight only as far as I
can see. Your suggestion contradicts with existing binding, though:
