how to set H5 chip run on 1.2GHz frequency #32

on default, H5 can only run on highest frequency 1008000Hz,but I want to set its highest frequency to 1200000Hz. I had tried to change some sorts of parameter setted in .dtsi file. But some how it could not work. Here is my setting: dvfs_table: dvfs_table { compatible = "allwinner,dvfs_table"; max_freq = <1200000000>; min_freq = <720000000>; lv_count = <8>; lv1_freq = <1200000000>; lv1_volt = <1300>; lv2_freq = <1008000000>; lv2_volt = <1100>; lv3_freq = <816000000>; lv3_volt = <1100>; lv4_freq = <648000000>; lv4_volt = <1100>; lv5_freq = <0>; lv5_volt = <1100>; lv6_freq = <0>; lv6_volt = <1100>; lv7_freq = <0>; lv7_volt = <1100>; lv8_freq = <0>; lv8_volt = <1100>; }; Do you have any idea to solve this problem?
