Steven Price 22bd4df9da drm/panfrost: devfreq: Round frequencies to OPPs ... Currently when setting a frequency in panfrost_devfreq_target the returned frequency is the actual frequency that the clock driver reports (the return of clk_get_rate()). However, where the provided OPPs don't precisely match the frequencies that the clock actually achieves devfreq will then complain (repeatedly): devfreq devfreq0: Couldn't update frequency transition information. To avoid this change panfrost_devfreq_target() to fetch the opp using devfreq_recommened_opp() and not actually query the clock for the frequency. A similar problem exists with panfrost_devfreq_get_cur_freq(), but in this case because the function is optional we can just remove it and devfreq will fall back to using the previously set frequency.
