[PATCH 1/3] dt-bindings: mfd: as3722: Drop reference to pm_power_off

[PATCH 1/3] dt-bindings: mfd: as3722: Drop reference to pm_power_off

[Thierry Reding]

From: Guenter Roeck <linux@roeck-us.net>

Devicetree bindings are supposed to be operating system independent and
should thus not describe how a specific functionality is implemented in
Linux.

[PATCH 3/3] dt-bindings: power: reset: qnap-poweroff: Drop reference to pm_power_off

[Thierry Reding]

From: Guenter Roeck <linux@roeck-us.net>

Replace reference to pm_power_off (which is an implementation detail)
and replace it with a more generic description of the driver's
functionality.
