This adds the documentation for the devicetree bindings of the Mstar MSC313e timer driver, found from MSC313e SoCs and newer.

This is an rtc property. You would need to $ref rtc.yaml, but then that also says the node name is 'rtc'. But why do you need a start year for a clocksource?

+ maxItems: 1

+ timer@6040 {
