Subject: [PATCH v3 0/2] cpufreq: add cpufreq driver for Mediatek MT8173 SoC
Date: Mon, 20 Apr 2015 17:27:25 +0800	[thread overview]
Message-ID: <1429522047-16675-1-git-send-email-pi-cheng.chen@linaro.org> (raw)

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
