Hi, I've been testing your patches with a20 olinuxino lime2 & a10 lime I notice your cpu opp data reduces the voltage down to 0.9v for the lowest frequency, but all of the regulator nodes you added for cubieboard cubietruck etc, have the lower limit set to 1v. Did you test 0.9v on anything? The lime2 dts currently has 0.7v as the lower limit for dcdc2 and when it's dropped to an opp with cpu core voltage set to 0.9v the board starts crashing randomly very soon after. I'll post a patch shortly to raise the lime2 dcdc2 lower limit to 1v, but I think it's probably worth collecting some more data on how many boards will really be able to use that 0.9v setting. With the exception of altering the dcdc2 limits, I've not encountered any other problems. Iain -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
