Hello!
We have built the board based on imx6ull and we need to optimize our power consumption.
We can I do it?
Do i need to close the clocks by editing linux's clk-imx6ul.c file.
How c an I do it in device tree?
I need to disable usb phy ,pxp, audio clocks.
Thanks in advance
Vladimir

Hi Vladimir
one can check AN5345 6ULL Power Consumption Application Note
