HI Yuri Muhin,

Where we can set to achieve dropping of VDDARM_IN and VDDSOC_IN  to 0.9V (by asserting the PMIC_STBY_REQ).

Thanks

Hi Yuri Muhin,

I have solved the reboot issue with ldo_bypass_enable=<1>; in dts file. Previous case it is ldo_bypass_enable=<0>;.

Now after changing to ldo_bypass_enable=<1> it's resuming properly, But my VDDCORE(VDDARM_IN) is still 1.36V it should reduce to 0.9V.

where i need to change this one.

Thanks

Lavanya
