charset="utf-8" Partial-IO is a very low power mode in which nearly everything is powered off. Only pins of a few hardware units are kept sensitive and are capable to wakeup the SoC. The device nodes are marked as 'wakeup-source' but so are a lot of other device nodes as well that are not able to do a wakeup from Partial-IO. This creates the need to describe the device nodes that are capable of wakeup from Partial-IO. This patch adds a property with a list of these nodes defining which devices can be used as wakeup sources in Partial-IO.
