Hi,
I have made some reverse engineering on act8847 driver with a disassambler, it looks like the driver is customized and the code is not the same as Hyundai T7 kernel driver .
I noticed some big differences in the i2c_probe function, VOYO has some GPIO setting inside.
I think I can reverse the VOYO's act8847 driver, it will probably take at least 20 hours
