I have a device tree fot T507 with pins PE19 and PD22 that are used as an LED and fixed-regulator gpio. Both of these devices fall into devices_deferred (reg-fixed-voltage: can't get GPIO). Why?
<junari>
I suspect that this is due to the deleted pmic node

And one more question. In u-boot I can set pmic configuration. But in linux i2cdetect empty

Hmm, looks like ATF is involved
<Xogium>
yeah that doesn't surprise me, ATF is the one that handles power management to some extent
<Xogium>
about the pmic that is

Yes, it was because the AT-F switches pmic to rsb mode or something else ...

junari: reverse engineering in the european union is almost always allowed, as the law states that it is allowed for "compatibility" reasons
<libv>
and it usually is not hard to make a case for that
<libv>
the laws are different in the .us and other parts of the world
<libv>
reverse engineering != disassembling, and using that directly, or turning that disassembly into C code and using that though
<libv>
as that immediately runs into copyright issues
<junari>
libv: So, there are no problems to see how it works and add it to your program?
<junari>
I heard that there were some problems with the guys that make their own MS windows
<junari>
And the maximum that they can do is for one to look at the disassembled code in order to retell it to the second guy
<libv>
junari: again, what i explained is valid for europe
<libv>
and if there is a lot of scrutiny and/or a very litigious "affected" vendor, you might want to be more cautious
<libv>
junari: allwinner is a known GPL violator
<libv>
so if you are in the .eu and european laws apply, have at it
<junari>
I'm more interested in the question of whether the code obtained with the help of ghidra or hexrays is acceptable for ATF or U-Boot
<libv>
again, the code, no
<libv>
the info yes
<libv>
and you do not need to do a full clean room
<libv>
but you should not copy decompiled code
<libv>
mnemoc and i moved the wiki last night btw
<gamiee>
libv: great, thanks for the migration! 😊
<libv>
we fixed the png issue (which is actually a bug in mediawiki, where there still is one case where the moved images/ directory and the config variable is not used correctly)
<libv>
and the search is also fixed
<mnemoc>
alternative domain names (sunxi.org and sunxi-linux.org) aren't working yet though
<libv>
so we should have full functionality
<libv>
if you notice anything, give us a heads up
<libv>
gamiee: we are both glad that we have this massive todo off our respective lists :)
<mnemoc>
everything in smartctrl's output was at estimated life remaining 0 :p
<libv>
:)
<libv>
plenty!
