This is a resend/v2 of a "Stop AXP from crashing when enabling LDO3" series, posted by Olliver Schinagl in March 2017. Unfortunately it never got past initial discussion [1], but most Olimex Lime2 boards are still running into this bug.
Well, this is actually v3. Missed this paragraph when pushing out v3.
It happens :)
<snip> The initial discussion with some scope screenshots can be found in the linux-sunxi mailing list [0].
Just like I didn't see this bit but claimed to be to lazy to find links and pics :)
So thanks for that and thanks a lot for re-submitting this series!! Feel free to do the same for the linux bits. The patches should be clean enough to apply pretty easily [0].

P.S. I had not forgotten about you and have a labled box to go your way tomorrow :)
And the initial series were posted to u-boot mailing list [1].
