Status of unused peripherals

Hi to all,

my newbie question is: what is the default status of unused peripherals in an iMX6 chip?

 

I'm developing a custom board based on iMX6SX, and a lot of functionalities (ADC, CAN, PCI, and many more) are not used. What is their status when I power up board?

For example, speaking about u-boot only, most peripherals seems not to be touched at all: if I'm in u-boot, are them powered on? If yes, how can I power them off to bring down power consumption, also in Linux domain?

 

Thanks in advance.

Regards

Mauro
