pcf2127, pcf2129 and pca2129 support start-year and reset-source.No, the 2129 variant doesn't even have a reset output pin. Not sure if there's any way to reflect that, and it probably doesn't matter, since nobody's going to add the reset-source property to a 2129 node. But the commit message is a bit misleading.
Actually no, the INT pin can be used as a reset, the pcf/pca2129 can be used as a watchdog and so it may need the reset-source property. -- Alexandre Belloni, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
