TDA2E: change dsp frequency to OPP_HIGH on linux usecase

Part Number: TDA2E

Hi ,

i want to change dsp frequency on linux usecase to match the hardware specifications ,

and i found it seems to change these places,

uboot   

->\u-boot\u-boot\include\generated\autoconf.h  #define CONFIG_DRA7_DSPEVE_OPP_HIGH 1  (is it right? or the file is auto generated?if yes, which file is really needed to be set ?)

linux kernel device tree  

->\kernel\kernel\omap\arch\arm\boot\dts\dra7xx-clocks.dtsi 

dpll_dsp_ck: dpll_dsp_ck  assigned-clock-rates = <600000000>;   change to 750000000

dpll_dsp_m2_ck: dpll_dsp_m2_ck assigned-clock-rates = <600000000>;   change to 750000000

dpll_dsp_m3x2_ck: dpll_dsp_m3x2_ck assigned-clock-rates = <400000000>;  change to 500000000

dsp bios

-> links_fw\src\rtos\bios_app_common\tda2ex\dsp1\Dsp1.cfg  BIOS.cpuFreq.lo = 600000000; /* 600 MHz */   change to 750000000

all i need to change is only above?

my environment
