Subject: [PATCH v6 0/4] Add Mediatek MT8173 cpufreq driver
Date: Thu, 9 Jul 2015 18:27:37 +0800 [thread overview]
Message-ID: <1436437661-17606-1-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 v6:
- Move clock and regulator consumer properties document to the device tree
bindings documents of MT8173 CPU DVFS clock driver
- Add change log to describe what is implemented in the MT8173 cpufreq driver
- Add missed rcu_read_unlock() in the error path
- Move of_init_opp_table() call to make sure all required hardware resources
are already there before it is called
- Add comments to describe why both platform driver and deivce registration
codes are put in the initcall function
- Use the term "voltage tracking" instead of "voltage trace" according to an
internal SoC document
changes in v5:
- Move resource allocation code from init() into probe() and remove some unused
functions due to this change
- Fix descriptions for device tree binding document
- Address review comments for last version
- Register CPU cooling device
Changes in v4:
- Add bindings for MT8173 cpufreq driver
- Move OPP table back into device tree
- Address comments for last version
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
