Key_Cronus_Test=PM_REGRESS As part of undervolting code, the nack handling was modified to remove any amount of undervolting. This is because undervolting can be the cause of the droop and hence the nack. However, the original code didn't properly account for the freq and voltage update ordering. As a result, sometimes voltage would be updated before frequency/vdm/resclk update in the wrong order, and resulting in droop forever.
