Subject: [PATCH 2/4] dt-bindings: add domain-idle-state compatible to arm,idle-state
Date: Tue, 25 Oct 2016 08:26:37 -0700 [thread overview]
Message-ID: <1477409199-52182-3-git-send-email-lina.iyer@linaro.org> (raw)
In-Reply-To: <1477409199-52182-1-git-send-email-lina.iyer@linaro.org>
CPU's idle states are defined by the arm,idle-state compatible flag. PM
domains that can contains devices and other domains also has similar
definition for its idle state. Reuse the definition of arm,idle-state
for PM domains by allowing an addition compatible string
("domain-idle-state") to denote idle states that are specific to PM
Domains.
