<macc24> is adc supported on rk3326 in mainlien linux ?
<mmind00> macc24: yep ... I already had "talked" to te Odroid-Go's analog joystick via it ;-)
<macc24> mmind00: that was EXACTLY what i was going to do, got any patches?
<mmind00> macc24: tought so :-D ... https://lkml.org/lkml/2020/7/3/886 and I think the adc-joystick-driver did go into 5.10-rc finally
<macc24> yeah it went into 5.10
<macc24> i am thinking of switching deb-to-go to gmenunx instead of retroarch
<macc24> hippity hoppity your code is my property
<mmind00> :-D
<macc24> mmind00: did you also saw nothing in /sys/class/power_supply resembling a battery?
<mmind00> so far I've been runnig my device without the battery so didn't check ... but I don't think I added any battery node to the dts anyway

<macc24> mmind00: battery node is needed for linux rk817 driver to recognize rk817 battery?
<mmind00> macc24: I don't actually remember how the battery is read on the Go ... but I think I remember that something on the rk817 driver was missing for that whole thing
<robmur01> AFAIK only the regulator and RTC functions of RK817 have support upstream - I see no trace of the charger, audio codec, or whatever random other functions it has
<macc24> oh god
<robmur01> I still love how random the mix of PMIC+audio is :)
<robmur01> kinda harks back to the days of dedicated "companion chips"
<robmur01> "buy our CPU but also buy this because it's all the other stuff you need that we couldn't fit in the CPU"
<macc24> are there any plans to mainline missing stuff from downstream kernel?

<john01> I recently obtained a Station P1 (Possibly the same as ROC-RK3399-PC) and I've been struggling to get it to boot from SD Card. I built arm-trusted-binaries and u-boot myself, but does it require the trust blobs in order to boot? The broken english instructions on both RockChip Wiki and Firefly have me a bit confused.
<john01> for my SD Card, the only partitions so far are: dd if=idbloader.img of=sdb seek=64 && dd if=u-boot.itb of=sdb seek=16384
<john01> If it requires trust chain then perhaps I need to use the binaries and add additional partitions.

<robmur01> john01: if you're using the upstream U-Boot flow, the TF-A binary is included in u-boot.itb; it's not separate like in the downstream miniloader flow
<macc24> john01: have you tried with seek 512 on u-boot.itb?
<robmur01> of course, it's all to easy to forget to provide "BL31=..." to the U-Boot build, miss the very subtle error message buried in all the other output, and end up with an image that doesn't actually work... been there done that :)
<john01> SPI has the stock (very old U-boot from Firefly) with TF-A, I plan to disable that with jumper and have it fall back to SD. I did do the BL31 export :)
<macc24> yes you HAVE to disable spi flash chip
<macc24> or 0xff it out
<macc24> mmind00: btw if your odroid go2 hangs for no reason in linux it might be because disconnected battery
<macc24> hmm, did 5.10 broke display on odroid go2?
<john01> macc24: I'm looking for SP1_CLK jumper right? (First time doing this)... https://i.imgur.com/Yhe2HBx.png --> There are also several other SPI on board per
<macc24> john01: i have no idea
<john01> Well, what's riskier. Brick by flashing or brick by wrong jumper cable? xD
<john01> prefer not to have a paperweight
<macc24> if you have clip, cables and some other board with spidev tested you can poke #coreboot or #flashrom until someone helps you ;D

<macc24> mmind00: can you check if display is working for you on odroid go2?
<mmind00> macc24: I don't have it with me at the moment ... earliest sometime next week ... did something break?
<macc24> yeah i get pattern of white and gray-ish vertical stripes
<macc24> nothing in dmesg
<mmind00> macc24: I guess check which the clock summary to check if the dclk frequencies are correct ... (mount none /debug -t debugfs; cat /debug/clk_summary)
<mmind00> macc24: and after that the logs of dw_dsi in drivers/gpu/drm/bridge/synopsys for interesting changes
<mmind00> hmm dclk_vopb has the 17MHz I remember, so it's not that
<mmind00> I guess if push comes to show you could git-bisect between 5.9 and 5.10-rc1
<macc24> on downstream kernel: https://bpa.st/HMSQ
<macc24> dclk_vopb is 17000000 on downstream, but it's 17001000 on mainline
<macc24> not idea why
<macc24> mmind00: the newest change in drivers/gpu/drm/bridge/synopsys was week before i got my odroid go2
<inode> join #lisp
<inode> ugh, sorry

<macc24> mmind00: computer locked up while compilin... i'm done for this week
<mmind00> macc24: but the 5.9 release still works?
<robmur01> the off-by-1KHz thing is a longstanding rounding issue - see the discussion here https://lore.kernel.org/linux-rockchip/20200922203107.2932-2-vicencb@gmail.com/
<mmind00> macc24: "git bisect start; git bisect good v5.9; git bisect bad v5.10-rc1" and a lot of patience ;-)
<mmind00> robmur01: yeah but probably was there already when the display was still working
<robmur01> yup, according to git history it's been over a year since Doug last tried to improve that area
<robmur01> so it's unlikely to be involved in a recent regression unless possibly some *other* change has made the panel more sensitive to exact clocks? Seems unlikely TBH :/
