camera driver with no i2c communication

I have a camera hooked up to a TX1 that doesn’t use I2C over CSI for communications. There is a side channel being used.

Any tips on getting this to work? Can I register the i2c interface but just return 0/success on the regmap calls?

Is there anything besides the driver itself that is expecting to communicate via i2c?

It’s not must be i2c interface. You can fake it and use event sideband interface to control it.
