I was trying to find out where exactly the voltages for core and IVA are set in the code. Are they set whenever for every frequency change? - I see that the table is divided into OPP50, OPP100 and so on but was not able to trace the entire path. Also, does smartreflex framework uses the same path to change the voltages (omap446x_vdd_core_volt_data, omap446x_vdd_core_volt_data) Could anyone help me understand this or point to some documentation. > >> Does smart-reflex involves reprogramming only the mpu power line alone? >> > AVS strategies apply to all rails in TI SoCs which need such strategies. > > -- > Regards, > Nishanth Menon Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
