* dt-bindings: remove 'interrupt-parent' from bindingsRob Herring2018-07-251-1/+0
| | | | | | | | | | | | 'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

* drivers/rtc/rtc-palmas.c: support for backup battery chargingLaxman Dewangan2013-09-121-0/+33
Palmas series device like TPS65913, TPS80036 supports the backup battery for powering the RTC when no other energy source is available. The backup battery is optional, connected to the VBACKUP pin, and can be nonrechargeable or rechargeable. The rechargeable battery can be charged from the system supply using the backup battery charger. Add support for enabling charging of this backup battery. Also add the DT binding document and the new properties to have this support.
