Its a sensor hub (firmware in the device flash)connected on i2c lines with SoC.

Most likely that sensors will get initialized while the kernel is booting.

This may not be true on all platforms, though. I believe some platforms have the ability to offload sensor processing to other processors on the same SoC.

So, also the Micro SD Card Reader is mounted like a sensor, governed with an I2C protocol?
