On the Samsung platform, there is a oemidle () function, which realizes the method of reducing frequency and recovering back, you can realize the frequency-decreasing rise frequency here, and also can set the system frequencies when the Oeminit is initialized.

Because the main frequency and peripherals are closely related, so you have to consider the ratio of the frequency of the peripheral, lock frequency, and so on, it is recommended that this part of the compilation.

Of course, each CPU has its recommended frequency, it is not possible to rise too high, and the rising frequency to the voltage rise up.
