Hi all, I had a discussion with Heiko on IRC few days ago about adding shutdown support in act8865 pmic for Rockchip SoCs. While browsing on LXR in order to understand how other pmic handles this support I found that most of the time there is a custom property of the following form "vendor,system-power-controller". If the devicetree node contains this property then the corresponding device driver registers a power off handler. In my opinion, It would be nice to propose a generic and standard property for that purpose (it would avoid to have to define his own property each time we implement the support). I found that there is a property called "wakeup-source" to mark a device as wakable. See Documentation/devicetree/bindings/mfd/{stmpe.txt,cros-ec.txt} .We could have a property like this one for power down. I mean, this is the same thing except that it's a power off event (and not wakeup). What do you think ?
