MT8173 is a ARMv8 based SoC with 2 clusters. All CPUs in a single cluster share the same power and clock domain. This series tries to add cpufreq support for MT8173 SoC.
Changes in v3: - Implement MT8173 specific standalone cpufreq driver instead of using cpufreq-dt driver - Define OPP table in the driver source code until new OPP binding is ready
Changes in v2: - Add intermediate frequency support in cpufreq-dt driver - Use voltage scaling code of cpufreq-dt for little cluster instead of implementaion in notifier of mtk-cpufreq driver - Code refinement for mtk-cpufreq driver
