From e1922b5da0e6869f1850c4447bed0b9cb1cf5034 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonathan=20Neusch=C3=A4fer?= Date: Fri, 8 Jan 2021 17:30:04 +0100 Subject: dt-bindings: timer: nuvoton: Clarify that interrupt of timer 0 should be specified MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
