Subject: [PATCH v2] dt-bindings: timer: nuvoton: Clarify that interrupt of timer 0 should be specified
The NPCM750 Timer/Watchdog Controller has multiple interrupt lines,
connected to multiple timers. The driver uses timer 0 for timer
interrupts, so the interrupt line corresponding to timer 0 should be
specified in DT.
I removed the mention of "flags for falling edge", because the timer
controller uses high-level interrupts rather than falling-edge
interrupts, and whether flags should be specified is up the interrupt
controller's DT binding.
