otherwise linux doesn't find filesystem to boot
<apritzel>
jernej: so you cannot disable the whole regulator setup because it needs some regulators to be enabled?
<jernej>
correct
<jernej>
but that happens only on some variants it seems
<jernej>
and I don't have it
<apritzel>
and I guess you don't need HDMI, Ethernet and USB in U-Boot?
<apritzel>
because in this case I think smaeul's U-Boot AXP patches might do the trick already
<jernej>
will they land in 2023.4?

<apritzel>
the actual driver is in, but it's not enabled, and there are some smaller bits missing, for instance to activate all boot-on regulators
<apritzel>
(which is probably what's needed here)
<apritzel>
that's an Android TV box, I guess? So we don't have any real documentation?

<jernej>
yes, that's TV box and no docs. There are two PCB revisions, but I'm unsure if regulator design is the same between them.
<apritzel>
could it be that some voltages are too low at reset, and need to be adjusted? Say from 3.0V or 2.5V to to 3.3V?
<jernej>
does that code also adjust voltage levels?
<apritzel>
yes, it does
<apritzel>
as long as those levels are properly described in the DT, of course
<apritzel>
and I don't know how the DT has been obtained, if for instance the voltage levels haven been measured or read from AXP registers, in the running Android?
<jernej>
not sure,

smaeul: do you know of any plans for actually using the hwspinlock device? Are there (upcoming) drivers that are going to use that?
