    Subject[PATCH v10 4/7] cpufreq:exynos:Extend Exynos cpufreq driver to support boost framework
    Date
    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 v10:
    - None

    Changes for v9:
    - The exynos_cpufreq_attr[] has been replaced by generic_cpufreq_attr[],
    therefore the cpufreq_freq_attr_scaling_boost_freqs is now added at
    freq_table.c file.

    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
