The GT9764 is one of Giantec's VCM driver parts: the vendor's VCM driver
application note (AN971) covers GT9764, GT9767, GT9768, GT9769, GT9772 and
GT9778, describing the same 10-bit DAC with the AAC actuator-control
extensions. The existing driver drives it through the same register set,
so it is documented as one more compatible of this binding.

Sounds like a fallback comptible to gt9769 should be doable here?
