But, before I start reviewing this series, I have few comments. - We weren't able to use cpufreq-dt driver for big LITTLE platforms earlier, as it never had multi cluster support and we wanted clock-sharing information via DT. - That is all fixed now. - I want Samsung's big LITTLE platforms to use cpufreq-dt and drop arm_big_little driver completely. - The only case for which it (arm_big_little) driver might be useful is the IKS solution. Which I don't believe you are going to use in future :) My plan for the arm-big-little driver: - Migrate all platforms to use cpufreq-dt instead for non-IKS solution - Make arm-big-little driver arm-big-little-iks only driver. @Sudeep: What would it take you to use cpufreq-dt for ARM's platforms ? -- viresh -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
