| From | Ulf Hansson <> | Subject | [PATCH v10 13/27] drivers: firmware: psci: Support hierarchical CPU idle states | Date | Thu, 29 Nov 2018 18:46:46 +0100 |
| |
From: Lina Iyer <lina.iyer@linaro.org>
Currently CPU's idle states are represented in a flattened model, via the "cpu-idle-states" binding from within the CPU's device nodes.
Support the hierarchical layout, simply by converting to calling the new OF helper, of_get_cpu_state_node().
