[PATCH v5 05/15] cpuidle: dt: Support hierarchical CPU idle states
From: Ulf Hansson <hidden>
Date: 2019-12-30 14:44:19
Also in:
linux-arm-msm, linux-pm
Subsystem:
cpu idle time management framework, the rest · Maintainers:
"Rafael J. Wysocki", Daniel Lezcano, Linus Torvalds
From: Lina Iyer <redacted> 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().
