imx93evk, pmic_stby_req assertion from imx93

[sbmd_1234]

Hi there,

I am working on the imx93evk, I have built an image for the device through yocto.

I was searching for the code pmic_stby_req  assertion by imx93 and after that pmic behaving according to that signal and controlling DVS. But couldn't find appropriate.

Please help me understand this.

Thanks in advance.

Where we can check the pmic GPIO pin is getting high after the pmic_stby_req signal came from i.MX93 processor may be somewhere this pin is triggered I want to check how it is happening.

Thanks in advance.

Hi 
Thanks for your valuable reply!

Can we know how and when pmic is getting triggered for the pmic_stby_req signal may be in drivers/DTSI or other related files?

Thanks.
