[ZXlieC]

Here i have added IPA support and teseted it on xiaomi-lavender. Here you can read more info about that: https://wiki.postmarketos.org/wiki/Qualcomm_Snapdragon_660/630/636_(SDM660/SDM630/SDM636)#Modem_Subsystem

Here is commit for add IPA v2 driver: Xlie-Electronic-Customs@bb833a8

I saw that and wanted to revert your changes to wiki pages of lavender and soc, just haven't gotten to it. pmOS Wiki should reflect the state of what is packaged in pmOS, not the state of random fork. And as you noted yourself, mobile data is not working, which is main purpose of IPA driver. (we already know that, it was tried before and you didn't discover anything new, almost)

If you want to do it properly, send a MR, we'll go through the process. Or, send patches directly to LKML, that also works

Ok, i`m sorry that i have added this to pmOS page (really sorry, i have removed all my changes on sdm630/636/660 soc and xiaomi-lavender page).

Not a big problem.

I'd love to see a PR with those changes though (but you should use git cherry-pick to preserve Vladimir's commit authorship on ipa-lite driver).

Maybe having some IPA support is better that having none at all.
