Subject: [PATCH 1/3] dt-bindings: power: domain-idle-state: Add system-state
Date: Mon, 05 Oct 2026 20:59:42 +0530	[thread overview]
Message-ID: <20261005-s2idle_state-v1-1-3c402c66f388@oss.qualcomm.com> (raw)
In-Reply-To: <20261005-s2idle_state-v1-0-3c402c66f388@oss.qualcomm.com>

Some domain idle states require system-wide coordination and are not
applicable while the platform is up and running.

Add a boolean system-state property to describe these states.
