Correct, the CPU voltage is provided by a i2c controllable regulator (sy8106a) without any datasheet. I've found how to set the voltage in above SDK, but I first want test this carefully. There's also the problem that we have to use the OpenRISC core for power management (especially poweroff), since there is no external PMIC. This can be done later of course, but we should think about how to do it. Jens -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
