Tool/software: Linux
Hi Sir:
We want to modify the Linux device tree to let AM572x CPU can run from 5000Mhz to 1.5Ghz, we have reference below web-site : http://processors.wiki.ti.com/index.php/Linux_Porting_Guide_for_AM571x/AM570x_Speed_Grades
For original setting int the device tree are three speed steps
u32 dra7_opp_dsp_clk_rates[NUM_OPPS][OPP_DSP_CLK_NUM] =
{{}, /*OPP_LOW */
{600000000, 600000000, 400000000}, /* OPP_NOM */
{700000000, 700000000, 466666667}, /* OPP_OD */
{750000000, 750000000, 500000000}, /* OPP_HIGH */ };
How can we modify the relative files let Am572x can run form 500Mhz to 1.5Ghz?
Thanks.
