Default standby voltage for buck regulators - PF0100

Hey guys,


I am using i.MX6q sabresd board with MMPF0100 PMIC. The driver is setting standby voltage only for two buck regulators i.e SW1A and SW1C. How are the standby voltages for other buck regulators configured ? Is there any default behaviour when standby voltage is not configured ?


And, when android is put to sleep(by pressing power key and there are no wakelocks), I am not sure whether PMIC is entering standby mode or sleep mode. Could anyone tell me where in kernel, the processor is asserting PWRON/STAND BY pin of PMIC ? Where in kernel is power key interrupt handled and PMIC's pin is asserted ?
