WebOct 18, 2024 · However, the most likely candidate to trigger that parent change is a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. The other trigger would be a call to clk_set_parent(), but it's far less used, and it doesn't look like there's any obvious user for that clock. WebThe clock rate rounding shall be done by the EMC drivers because they have information about available memory timings, so the drivers will have to register a callback that will round the requested rate. ... clock users won't be able to request EMC clock by getting -EPROBE_DEFER until EMC driver is probed and the callback is set up.
