This OPP limiting is done as part of late initcall and if the cpufreq driver is built in the kernel, there will be a small window where the OPPs not supported are still enabled ? Will that not be an issue if say performance governor is selected by default.
Even if cpufreq driver is built in the kernel, it won't be probed until platform_device_register(&imx6q_cpufreq_pdev) is called. And we make this call only after the OPP limiting.
Ah right, I missed that. Thanks for clarifying.
