Our project uses Giantec VCM hardware. 
For detailed vendor information, please visit: (
https://en.giantec-semi.com/yqmd/164). 
The VCM datasheet we are referencing is provided by Giantec. 
Currently, the relationship between Giantec VCM and Dongwoon VCM is
unclear, but Dongwoon seems to be another manufacturer of VCM
hardware. 

From the perspective of software driver development and maintenance, it
makes sense for each vendor's hardware should have its own software
driver.
So, I upstream a new VCM driver for Giantec.
