Subject: [PATCH v2 4/4] ARM: dts: vt8500: list all four timer interrupts
Date: Wed, 07 May 2025 10:58:33 +0400 [thread overview]
Message-ID: <20250507-vt8500-timer-updates-v2-4-65e5d1b0855e@gmail.com> (raw)
In-Reply-To: <20250507-vt8500-timer-updates-v2-0-65e5d1b0855e@gmail.com>
VIA/WonderMedia SoC timer can generate up to four interrupts corresponding
to four timer match registers (firing when the 32-bit freerunning clock
source counter matches either of the match registers, respectively).
List all four interrupts in device trees.
This also enables the system event timer to use a match register other
than 0, which can then in turn be used as a system watchdog (watchdog
function is not available on other channels)
