    Subject[PATCH v6 6/8] 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 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
