| From | Lukasz Majewski <> | Subject | [PATCH RESEND v8 5/7] cpufreq:exynos:Extend Exynos cpufreq driver to support boost framework | Date | Fri, 20 Sep 2013 18:01:02 +0200 |
| |
The cpufreq_driver's boost_supported flag is true only when boost support is explicitly enabled. Boost related attributes are exported only under the same condition.

--- Changes for v8: - None
Changes for v7: - Replace CONFIG_CPU_FREQ_BOOST_SW with CONFIG_ARM_EXYNOS_CPU_FREQ_BOOST_SW - Move boost_supported initialization to struct cpufreq_driver exynos_driver
Changes for v6: - Replace exynos_driver.boost_supported = 1 to = true - Protect boost attributes export with CONFIG_CPU_FREQ_BOOST_SW
Changes for v5: - None
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
