hi all On the 2.6.37 , I've seen that when I set enable_off_mode mode through debug-fs, VDD1 ( as measured across pin 2 of J6 and GND on OMAP3 EVM) increases from a nominal value of 1.225 V to 1.247 V. When the uart finally times-out and the mpu_pwrdm enters OFF mode, it finally goes down to 1.237 V, which is still more than the nominal value. This unexpected behaviour is in contrast to a 2.6.32 kernel that I tried with. On probing further, I found that the VDD1 increase is happening when forced wakeup is called on the iva2_clkdm clockdomain in omap_set_pwrdm_state() as a response to setting the enable_off_mode flag. It seems that after boot-up the iva2_pwrdm is in RET state from where its clock-domain needs to be force waken up before having its automatic Hardware supervised transition bit-field set (reg field CM_CLKSTCTRL_IVA2.CLKTRCTRL_IVA2). Why is this so ? Any inputs would be appreciated. regards Abhilash-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
