Subject: [PATCH 07/13] cpuidle: psci: Support hierarchical CPU idle states
Date: Thu, 10 Oct 2019 13:39:31 +0200 [thread overview]
Message-ID: <20191010113937.15962-8-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20191010113937.15962-1-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().
