After datasheet update for TMS320DM8168 we found that frequency values for TMS320DM8168CCGY--
chancged from 1.0-GHz ARM, 800-MHz DSP to 930-MHz ARM, 750-MHz DSP.
Currently we use the following frequency values:
ARM clk: 1000 MHz
DDR clk: 796 MHz
HDVICP ckl: 600 MHz
L3 fast clk: 560 MHz
HDVPSS clk: 280MHz
Ducati M3 clk: 280 MHz
DSP ckl: 800 MHz
Our values in clocks_ti816x.h:
/* Main PLL */
#define MAIN_N 56
#define MAIN_P 0x1
#define MAIN_INTFREQ1 15
#define MAIN_FRACFREQ1 0x1EB851
#define MAIN_MDIV1 0x1
#define MAIN_INTFREQ2 12
#define MAIN_FRACFREQ2 0x189374
#define MAIN_MDIV2 0x1
/* For IVAHD @ 600MHz*/
#define MAIN_INTFREQ3 10
#define MAIN_FRACFREQ3 0x147AE1
#define MAIN_MDIV3 0x2
#define MAIN_INTFREQ4 10
#define MAIN_FRACFREQ4 0xCCCCCC
#define MAIN_MDIV4 0x2
#define MAIN_INTFREQ5 12
#define MAIN_FRACFREQ5 0x189374
#define MAIN_MDIV5 8
#define MAIN_MDIV6 0x3F
#define MAIN_MDIV7 0x4
What values are recommended to set 930 for ARM and 750 for DSP ?
Do we have influence if we change ARM and DSP frequency to the other frequency values ?
Can we use the former values for DDR and the other clocks ?
