10:17 < geertu> Marex: Core related? I should hand over the mic to Wolfram...
10:17 < Marex> shimoda: I sent out the xhci patch I plan to submit to the U-Boot list to the periperi list first, the license grant should be OK, can you double-check please ?
10:18 < Marex> geertu: well it's inbetween, U-Boot is core and xhci is IO
10:18 < shimoda> Marex: sure, I will check it
10:18 < Marex> shimoda: thank you !
10:18 < Marex> shimoda: it'd be convenient if this worked out, since now I can just type "usb reset" and it works :)
10:19 < Marex> shimoda: it's hassle-free
10:19 < shimoda> Marex: nice! :)
10:20 < wsa_> geertu: don't worry, I am fine
10:20 < Marex> shimoda: btw re HS200/400 and SDR104, I am a bit blocked by the SD/MMC maintainer in U-Boot, sorry about that
10:20 < Marex> shimoda: he's not picking patches as fast as I'd like him to
10:20 < Marex> shimoda: I'm looking for ways to ... uh ... expedite that process
10:21 < shimoda> Marex: i got it. thanks!
10:21 < Marex> shimoda: you're welcome, I'll keep you updated
10:22 < wsa_> Marex: is yamada-san working on this, too?
10:22 < Marex> wsa_: Masahiro Yamada-san ?
10:22 < wsa_> hai
10:22 < Marex> wsa_: he works for socionext, although he did implement the uniphier-sd which I now use on RCar Gen3
10:22  * neg brb 2 min
10:22 < Marex> wsa_: their block doesn't support the HS200/400/SDR104 modes though, that's renesas specific
10:23 < Marex> wsa_: so he just reviews my uniphier-sd patches (which is nice) and makes sure they work on both
10:23 < wsa_> I see
10:24 < Marex> wsa_: the blocker really is the SD/MMC subsystem maintainer, he just doesn't respond much
10:24 < Marex> wsa_: some not long time ago I was really tempted to just replace him and start handling the SDMMC stuff myself
10:25 < Marex> wsa_: but then he came back, at like 5 mins to 12 and rolled out a PR ...
10:25 < wsa_> how about co-maintaining?
10:25 < Marex> wsa_: I feel like I'm hoarding functions ;-)
10:26 < wsa_> I see
10:26 < wsa_> that happens easily, yes
10:26 < Marex> wsa_: right
10:26  * neg back
10:26 < Marex> wsa_: and since U-Boot isn't as prestigeous as linux, maintainers don't really queue up to do it
10:27 < wsa_> okay
10:27 < Marex> wsa_: anyway ... maybe we should continue rather than complain about lack of manpower all over the place ? :)
10:27 < wsa_> ack
10:29 < wsa_> geertu: can i take over? or did i already? :)
10:29 < geertu> wsa_: I think you already did
10:30 < jmondi> ETHER is working as well \o/ (sorry to jump in with random messages, is rude, but I'm happy, now the peach is a grown up baby!)
10:30 < wsa_> well, then: welcome to the already started io meeting :D
10:30 < wsa_> jmondi: no problem, but only for success messages ;)
10:31 < jmondi> wsa_: I would be mostly silent then :)
10:31 < wsa_> ok, i collected (and rephrased) the ABC questions
10:31 < wsa_> and added a comment here and there, here they go:
10:31 < wsa_> A)
10:31 < wsa_> 	* Geert worked on RAVB PHY reset to support supsend/resume
10:31 < wsa_> 	* Niklas did SDR104/SDIO tests on Koelsch
10:31 < wsa_> 	* Simon got the RAVB RX checksum offload patch merged
10:31 < wsa_> 	* Uli got the HSCIF HW timeout patch merged and resent the HSCIF sampling point shift patch
10:31 < wsa_> 	  (the latter raised a few comments, though)
10:31 < wsa_> 	* Shimoda-san got f_printer driver merged and fixed quite some USB issues and added quite some
10:31 < wsa_> 	  DT nodes, and added suspense/resume support for USB PHY
10:31 < wsa_> 	* Wolfram discussed add. tasks and upport lists, added I2C to Salvator-XS, resend the eMMC drive
10:31 < wsa_> 	  strength patches, and commented on SDHI SDR104 tests and regulator patches
10:31 < wsa_> B)
10:31 < wsa_> 	* Geert will keep an eye to get RAVB PHY reset working and wants to tackle MSIOF again
10:31 < wsa_> 	  (multiple chip selects, I assume?)
10:31 < wsa_> 	* Simon starts working on HS400
10:31 < wsa_> 	  (nice timing because Marek works on HS400 for U-Boot currently)
10:31 < wsa_> 	* I assume Uli will keep working on the sampling point patch?
10:31 < wsa_> 	* Shimoda-san works on the USBHS driver more if he gets feedback from HW team
10:31 < wsa_> 	* Wolfram wants to finalize the I2C DMA patches, improve the I2C fault injector and start
10:31 < wsa_> 	  preparing the talk & showcase about it for ELCE, debug SDR104 on Gen2, and add. tasks
10:31 < wsa_> 	  plus upport lists, of course.
10:31 < wsa_> C)
10:31 < wsa_> 	* Shimoda-san's patches for USB2.0 phy for r8a77995 got no feedback from PHY maintainer
10:31 < wsa_> 	* Wolfram wonders where all the time since San Sebastian has gone
10:32 < wsa_> please have a look if everything is correct or i missed something
10:33 < geertu> wsa_: German tax rate is how many %? ;-)
10:34 < wsa_> too many :D
10:35 < wsa_> it stops at 42% IIRC
10:35 < wsa_> okay, there don't seem to be any comments
10:35 < wsa_> other than taxes
10:35 < horms> HS400 will be fun, but the fun hasn't started yet. Tax is less fun, we can swap notes another time.
10:36 < Marex> horms: HS400 seems like HS200 DDR, why the worry ?
10:36 < wsa_> I don't really have other topics for now; I'd think the SDR stuff and the upport list discussion are better suited for emails currently
10:36 < wsa_> unless there is something you guys want to discuss right now
10:37 < horms> Marex: thanks for the encoragement :)
10:38 < Marex> horms: well I was serious, it doesn't seem all that different
10:38 < wsa_> at least we won't have "long cable" problems with HS400 :)
10:38 < Marex> ^_^'
10:38 < geertu> wsa_: Why not?
10:38 < wsa_> HS400 is eMMC only
10:38 < horms> eMMC is on the board
10:40 < wsa_> dammsan: do you need anything from me regarding add. tasks?
10:40 < geertu> UHS-III is even faster, and using actual cards?
10:41 < wsa_> looks like it
10:42 < wsa_> maybe microsd only, though
10:42 < Marex> wsa_: they use PCIe-like bus
10:42 < Marex> for UHS3 that is
10:43 < Marex> the full-size UHS3 cards have extra pads for that, differential ones
10:43 < Marex> I think the bus might even be PCIe compatible right away
10:43 < wsa_> heh
10:44 < Marex> well that's where it's all headed anyway
10:44 < wsa_> let's see what comes out of that :)
10:44 < Marex> USB3 and PCIe use the same physical layer, the SD probably joins that too
10:44 < Marex> shimoda: I just received USB3 Totalphase Beagle 5000 V2 :-3
10:44 < wsa_> let's see how this will all end up in some R-Car Generation
10:45 < wsa_> but for now, it is SDR104 and HS400 :)
10:45 < wsa_> so, last call for topics from your side
10:46 < wsa_> aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaand we are done!
10:46 < wsa_> Thank you guys!
10:46 < neg> thanks all
10:46 < shimoda> Marex: wow! nice!
10:46 < shimoda> thank you!
10:47 < jmondi> thank you all!
10:47 < Marex> thank you all!
10:47 < jmondi> neg: pinchartl: kbingham: catch you later
10:47 < uli__> see you
10:47 < horms> wsa_: were we going to talk about upporting about now?
10:48 < wsa_> i don't think so
10:48 < wsa_> i mean we can do
10:48 < wsa_> but i think it would be good to have morimoto-san here, too
10:48 < Marex> shimoda: jupp, so many hard-to-debug USB problems are hopefully fixed soon :)
10:48 < horms> Sure. Perhaps we can continue the discussion via email.
10:48 < wsa_> i'd suggest to keep discussing via email until then
10:49 < wsa_> ;D
10:49 < shimoda> Marex: I hope so :)
10:49 < horms> my question for you would be: do you think it would be more useful for Kaneko-san to help with keeping the upport list up to date, or to focus on upporting trivial patches
10:52 < wsa_> hmmm
10:53 -!- horms [~horms@217.111.208.18] has quit Quit: Leaving
10:55 < wsa_> seems this answer also needs to go via email...
