ChanServ changed the topic of #aarch64-laptops to: Linux support for AArch64 Laptops (Asus NovaGo TP370QL - HP Envy x2 - Lenovo Mixx 630 - Lenovo Yoga C630)

qzed: there might still be issues with "unused" regulators being turned off etc, but you should be able to retain efifb up until you modprobe msm
<bamse>
qzed: is your adreno update saying that your 690 is a 680?
<qzed>
bamse: yeah, I'm pretty sure now that the "Microsoft SQ2 Adreno 690" is in reality a 680, probably overclocked
<qzed>
I've replaced the gpio-controlled regulator in my dp with "enable-gpios" on the panel
<qzed>
that doesn't power-cycle until the panel is actually probed, so I get output until at least then
<bamse>
that would make much more sense that some sc8180x are 680 and some are 690...
<qzed>
yeah I guess
<bamse>
looking at the sc8280xp, there seems to be some definite differences in the kgsl driver...so that doesn't seem to be 680
<qzed>
I do kinda wonder what the Adreno 685 is then that's supposedly in the SQ1
<robclark>
qzed: odds of EC detecting AP doing something with the panel are much lower than odds of AP doing something to disrupt the delicate balance of panel working (like toggling some gpio or regulator)
<robclark>
would be interested in dump of first few dwords worth gpu regs from 680.. I'll do same for sc7180 vs sc7180p when I'm in the office next week
<qzed>
yeah, that's the second part now, I guess... anyways, I now have at least output until msm/panel probe
<robclark>
with these things, there is a whole lot more than can possibly go wrong than what can go right ;-)
<qzed>
yeah, I'm starting to realize that xD
<HdkR>
Once you get far enough along, I can throw your work at the first gen ProX that I have, see if it explodes.
<bamse>
qzed: on sc8280xp we ran into the problem that 30 seconds after boot regulators would be turned off, which would cut the seemingly unused power to the edp phy
<qzed>
feel free to do that, I guess there shouldn't be many differences... I'd have thought GPU would be the main one but apparently that's still a 680
<bamse>
qzed: so had to sprinkle some regulator-always-on in a few places
<qzed>
huh interesting, I'll have to try that
<bamse>
qzed: you have a pair of 0.9 and 1.2V supplies for the edp phy
<qzed>
I had planned on printing out regulator transitions anyways at some point if I didn't find something else
<qzed>
yeah, although I'm not sure if they should be there or on the mdss_edp or on both...
<bamse>
there are only power-domains on the controller...and then the two phy supplies should be listed in &mdss_edp
<bamse>
if that's what you're saying
<qzed>
I've mostly gone off the sc7280-qcard.dtsi on that one and added the ones that fit from my schematic
