2020-09-24dt-bindings: rtc: ds1307: add rx8130 aux-voltage-chargeable supportBastian Krause1-1/+1
Epson's RX8130 was not charged before. A related patch will allow optional charging.

trickle-diode-disable trickle-diode-disable is deprecated, so reflect that in the driver's binding and add the new aux-voltage-chargeable.

2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring1-1/+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.

2018-07-17rtc: ds1307: support m41t11 variantGiulio Benetti1-0/+1
The m41t11 variant is very similar to the already supported m41t00 and m41t0, but it has also 56 bytes of NVRAM. Add it to driver taking into account NVRAM section.
