Wysocki" , Zhang Rui , Eduardo Valentin Cc: "cpufreq@vger.kernel.org" , Linux PM list , Jonghwa Lee , Lukasz Majewski , l.majewski@majess.pl, linux-kernel , Andre Przywara , Daniel Lezcano , Kukjin Kim , Myungjoo Ham 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.
