| From | Lukasz Majewski <> | Subject | [PATCH v4 4/7] cpufreq:exynos:Extend Exynos cpufreq driver to support boost framework | Date | Wed, 19 Jun 2013 19:12:45 +0200 |
| |
The struct cpufreq_driver has been extended to embrace the information related to boost support.
When "boost_mode" device tree attribute is defined for a platform, the boost_supported flag is set. Moreover boost related attributes were exported.

Changes for v4: - None
Changes for v3: - Remove low level boost code - Move boost management code to cpufreq core code - Use boost_supported flag to indicate if driver supports over clocking
Changes for v2: - Removal of struct cpufreq_boost - Removal of the CONFIG_CPU_FREQ_BOOST flag - low_level_boost with valid address when boost is supported --- drivers/cpufreq/exynos-cpufreq.c | 4 ++++ 1 file changed, 4 insertions(+)
