The imx412 like many I2C camera sensors has three voltage rails which depending on platform may be necessary to switch power onto directly. Add in as optional rails so as not to break anything for existing users.

IMX412 sensor is a Sony CMOS active pixel digital image sensor with an active
|
|
array size of 4072H x 3176V. It is programmable through I2C interface. The
|
|
I2C client address is fixed to 0x1a as per sensor data sheet. Image data is
|
|
sent through MIPI CSI-2.
