Hi vanakt, sorry for late reply i was kind of busy... If u r using OMAP35XX based board then i will assume it's PMIC will be TPS65950 or similar.It's Data sheet manual is here - http://www.ti.com/lit/ds/swcs032e/swcs032e.pdf and u can find it's manuals at TI site i guess. BUT the power states u mentioned are CPU/system power states.From what i understand, u r trying to do basic power management like cutting off power supply to unwanted device and peripherals like camera,speaker,vibration motor etc. when not in use. The above links will lead u in that direction(not directly but eventually). The link Arun mentioned deals with info on what devices stay active or inactive in each of the power states & try to optimize consumtion and not how to control and interface them. Interfacing them and getting power management to work in different(links i mentioned) *AND* Managing and optimizing the power consumption is different(links Arun mentioned) . Only one of these will help u. Choose which stage u r in exactly
If u get back on what exactly u r trying to do, i can help more.
