Optional properties:
of: Rename "poweroff-source" property to "system-power-controller" It reverts commit a4b4e0461ec5 ("of: Add standard property for poweroff capability"). As discussed on the mailing list, it makes more sense to rename back to the old established property name, without the vendor prefix. Problem being that the word "source" usually tends to be used for inputs and that is out of control of the OS. The poweroff capability is an output which simply turns the system-power off. Also, this property might be used by drivers which power-off the system and power back on subsequent RTC alarms. This seems to suggest to remove "poweroff" from the property name and to choose "system-power-controller" as the more generic name. This patchs adds the required renaming changes and defines an helper function which checks if this property is set.

regulator: act8865: add DT binding for property "active-semi,vsel-high" Add a DT property "active-semi,vsel-high" to indicate the VSEL pin is high.

regulator: act8865: add input supply handling The act88600/act8846/act8865 regulators have a number of input supplies supplying the individual regulators. This may even be recursively like on most Rockchip boards using the act8846 where REG4 is most of the time connected to the inl1-supply. Therefore add the ability to specify the input supplies for the individual inputs. The input-names are taken from the datasheets of act8600, act8846 and act8865. On the act8600 some regulators do not have separate input supplies. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Mark Brown <broonie@kernel.org>
