Hence, my question is if the clocks are active, Will disabling the domain take effect? Because when i print the status - they show that the domain is OFF. On my system, what i see is camera clocks are active, But the domain is OFF. Hence, i am not sure if camera subsystem is consuming power or not since clocks are on. >From my understanding, the domain status should not indicate OFF if any clocks are still on. > Best regards, > Krzysztof -- Regards, Sriram -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
