Subject: [PATCH v2 1/5] dt-bindings: timer: econet: Update EN751627 for multi-IRQ
Date: Thu, 14 May 2026 00:05:57 +0000	[thread overview]
Message-ID: <20260514000601.3430262-2-cjd@cjdns.fr> (raw)
In-Reply-To: <20260514000601.3430262-1-cjd@cjdns.fr>

This hardware is found in the EN751221 SoC family as well as the
EN751627. The former uses a percpu IRQ for all timers while the
later uses an individual IRQ numbers per-timer.
