: The name of this implementation.
struct s3c_cpufreq_info - Information for the CPU frequency driver. : The maximum frequencies for the system. : Transition latency to give to cpufreq. : The lock-time in uS for the MPLL. : The lock-time in uS for the UPLL. : The number of bits each LOCKTIME field. : Set if this driver needs to change the PLL values to achieve any frequency changes. This is really only need by devices like the S3C2410 where there is no or limited divider between the PLL and the ARMCLK. : Update the clocks on resume. : Get the current IO timing data, mainly for use at start. : Update the IO timings from the cached copies calculated from the entry when changing the frequency. : Calculate and update the cached copies of the IO timings from the newly calculated frequencies. : Calculate (fill in) the given frequency table from the current frequency configuration. If the table passed in is NULL, then the return is the number of elements to be filled for allocation of the table. : Set the memory refresh configuration. : Set the PLL frequencies. : Update the clock divisors. : Calculate the clock divisors.
