Subject: [PATCH v2 07/13] cpuidle: psci: Support hierarchical CPU idle states
Date: Tue, 29 Oct 2019 17:44:32 +0100 [thread overview]
Message-ID: <20191029164438.17012-8-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20191029164438.17012-1-ulf.hansson@linaro.org>
Currently CPU's idle states are represented using the flattened model.
Let's add support for the hierarchical layout, via converting to use
of_get_cpu_state_node().
