23 * OMAP4 ABE DPLL default frequency. In OMAP4460 TRM version V, section
24 * "3.6.3.2.3 CM1_ABE Clock Generator" states that the "DPLL_ABE_X2_CLK
25 * must be set to 196.608 MHz" and hence, the DPLL locked frequency is
28 #define OMAP4_DPLL_ABE_DEFFREQ 98304000
31 * OMAP4 USB DPLL default frequency. In OMAP4430 TRM version V, section
32 * "3.6.3.9.5 DPLL_USB Preferred Settings" shows that the preferred
33 * locked frequency for the USB DPLL is 960MHz.
