| SPEAr cpufreq driver | |
| ------------------- | |
| SPEAr SoC cpufreq driver for CPU frequency scaling. | |
| It supports both uniprocessor (UP) and symmetric multiprocessor (SMP) systems | |
| which share clock across all CPUs. | |
| Required properties: | |
| - cpufreq_tbl: Table of frequencies CPU could be transitioned into, in the | |
| increasing order. | |
| Optional properties: | |
| - clock-latency: Specify the possible maximum transition latency for clock, in | |
| unit of nanoseconds. | |
| Both required and optional properties listed above must be defined under node | |
| /cpus/cpu@0. | |
| Examples: | |
| -------- | |
| cpus { | |
| <...> | |
| cpu@0 { | |
| compatible = "arm,cortex-a9"; | |
| reg = <0>; | |
| <...> | |
| cpufreq_tbl = < 166000 | |
| 200000 | |
| 250000 | |
| 300000 | |
| 400000 | |
| 500000 | |
| 600000 >; | |
| }; | |
