All Pi cameras use the GPIO on the FFC to control the regulators and clock on the camera board.
The GPIO is handled through the Linux regulator framework as cam1_reg or cam0_reg depending on which port you're looking at.
When the regulator is enabled, imx219 will respond on 0x10. If not enabled, you'll get -EREMOTEIO due to no ACK on the I2C.
