No, it wasn't. Like for many i2c devices, the driver predates DT and
didn't need any specific code to be used from DT. Basically, the i2c
core was using the i2c_device_ids to match the DT compatible string.
This is changing since cabcf4f6be658b2d4bea26dee89d08fdf67d6811.
I'm planning to document all the undocumented ones soon.
