Agreed. What I wrote was just the default policy setting for the Power-On state. > Oh and do not spend too much time on standby, new computers usually do > not support it anyway. If we have suspend-to-ram working, there's no > reason using standby. I suspect that once the other states are implemented, Standby won't add much extra. By the way, I see that the power tree agrees pretty much with the device tree, but there is the possibility of having a different parent pointer. However the device_pm_set_parent() routine isn't called anywhere in the kernel. Does that mean it can be eliminated, making the two trees identical? Isn't is also true that if a device requires a power-parent other than its normal parent, that it may actually require multiple power-parents? So a single extra pointer won't really be enough of a help. Part of the reason for asking is because of selective suspend. If the power tree includes parent pointers but not children pointers, you run the risk of selectively suspending a device while leaving its children turned on.
