devfreq already provides a sysfs interface for changing polling/sampling period. So, there is no need for the governor to separately expose sampling_ms. Also, sampling_ms had to be explicitly updated whenever polling_ms was updated for the governor to function correctly. Make the interface simpler by combining sample_ms with polling_interval control provided by devfreq. The rounding of freq to multiples of bw_step is unnecessary since the devfreq device already does the rounding to the next valid level. Rounding of AB to multiples of bw_step is still necessary since it's a vote that's summed up and doesn't have a direct 1-to-1 mapping to frequencies. Also update default bw_step to 190 MB/s instead of 200 MB/s to account for the fact that MB/s to MHz conversion needs to take into account the difference in the meaning of M (2^20 vs 10^6) between MB and MHz. Similarly also update io_percent to 16. Change-Id: I5fea989c647955103de3813be8eb9ec612f131bc Signed-off-by: Saravana Kannan <skannan@codeaurora.org>
