rk3399 platform have dfi controller can monitor ddr load, and dcf controller to handle ddr register so we can get the right ddr frequency and make ddr controller happy work(which will implement in bl31). So we do ddr frequency scaling with following flow:
kernel bl31monitor ddr load | | get_target_rate | | pass rate to bl31 clk_set_rate(ddr) --------------------->run dcf flow | | | | wait dcf interrupt<-------------------trigger dcf interrupt | | return

The cover-letter includes the duplicate list of patches.
Also, I want to test the build test. but, When I apply these patches, merge conflict happen. Could you give the information about base git repository?
