17:24 <c0d3z3r0> mmind00: I had a look at the act8846 datasheet and the rock schematic again. it seems that the power cycle does not reset the voltages.

17:25 <c0d3z3r0> that's what naobsd suspected yesterday

17:25 <c0d3z3r0> I'm not really sure what pwrhold does but the reset key pulls down pwrhold to do a reset as you said and that seems to work. the rk3188 is connected to pwrhld through GPIO0_A0 / AC4 so we could reset the rock by pulling that pin down.

17:26 <c0d3z3r0> since that is a board specific thing it would be a good idea to set the pin via dts and add an additional restart handler accordingly.

17:26 <c0d3z3r0> the only problem I see for now is that we cannot pull it up again and reenable the regulator. what do you think about that?

19:00 <mmind00> c0d3z3r0: hmm, I guess simply try drivers/power/reset/gpio-restart.c [temporarily increase its priority above the current 128) and see what happens? :-)

19:02 <c0d3z3r0> mmind00: how can I get the right gpio number for GPIO0_B[2]? I've been searching for hours but didn't really find anything :/

19:03 <mmind00> c0d3z3r0: a[0-7] = 0-7, b[0-7] = 8-15, c[0-7] = 16-23, d[0-7] = 24-31

19:04 <c0d3z3r0> oh nice :D

19:04 <c0d3z3r0> thx :)

19:06 <c0d3z3r0> mh ok.. now it's completely off. that's not what we wanted

19:06 <c0d3z3r0> damn

19:24 <c0d3z3r0> oh.. pwr_hold is not connected to pwrhold. that couldn't work

19:24 <c0d3z3r0> I would have needed to pull PWR_EN down but there is no gpio connected
