Dear friend

My platform is IMX8QXP MEK. Linux 5.4.70.

I want to do some change on PMIC control, can you provide information about where I can do some modification in code? And also, other info related are welcome.

Hi,

PMIC control by SCU. so, You need investigating the SCFW porting kit.

Also, following information will be useful.
