Hi,
i am working on OMAP2430
i want to provide clock speed selection of dpll, ARM speed and L3/ddr speed through make menuconfig

in the function "omap2_select_table_rate" in file arch/arm/mach-omap2/clock24xx.c, if the current dpll speed is twice or half of the currenlty programmed dpll
value, is calls "omap2_reprogram_sdrc" function. Else only it configures the value given in rate table.

So even if i want to change the L3 clock with different speed with dpll and arm at same speed i am not able to(x-load/u-boot has initialized dpll at 660 and arm at 330)

Also what is the purpose of function
"omap2_reprogram_sdrc"

Any suggestion on fix

Regards
Sharath
