08:56 <@horms> hi wsa_ 
08:59 < wsa_> hi simon
08:59 <@horms> how are things?
09:02 < wsa_> windy :D
09:02 -!- shimoda [~shimoda@relprex2.renesas.com] has joined #periperi-io
09:03 < wsa_> lots of things are changing currently
09:03 < wsa_> this is nothing bad per se, but needs lot of attention
09:03 <@horms> good luck :)
09:03 -!- geertu [~geert@d54c36a7b.access.telenet.be] has joined #periperi-io
09:03 < wsa_> thanks!
09:03 < wsa_> hello shimoda-san
09:04 < shimoda> hello wolfram-san
09:04 < geertu> (sorry, i was in the wrong channel)
09:06 < wsa_> geertu: no worries, i'll be in both channels and point to this one if necessary

09:06 < morimoto> Hi
09:07 <@horms> Hi Morimoto-san, hi Geert
09:07 < geertu> {Mor,Eve}nin' again ;-)
09:08 < wsa_> Hi Morimoto-san
09:08 < wsa_> so, we are all here
09:08 < wsa_> let's start
09:09 < wsa_> looking at the patches in renesas-soc, I didn't see much  updates to the todo.
09:09 < wsa_> Please update me if I missed something
09:09 < geertu> MSIOF,v4.6,plan,geert,Investigate issues on Gen3 => complete
09:10 < wsa_> I wonder though, if we should add some tasks which are happening but haven't been formalized yet?
09:10 < wsa_> like the review support for the CAN driver?
09:11 < wsa_> or the DMA support for ravb (by Kaneko-san)?
09:11 < wsa_> opinions on this?
09:11 <@horms> Kaneko-san's work is covered by tasks in the upporting portion of the wiki etc...
09:11 < geertu> IMHO review is part of the job
09:11 <@horms> I don't object to you adding tasks too, but just so you know that I am tracking his work
09:12 < wsa_> ok, so this is considered upporting because it comes from the BSP. fair enough
09:12 <@horms> I would be more inclined to add a can task and assign it to whoever is working on it, even if they are outside the group. But I have no strong opinions here
09:13 <@horms> wsa_: yes, its coming from the bsp. obviously it also overlaps with this group
09:14 < wsa_> geertu: that was a HW issue with MSIOF, right?
09:14 < geertu> I aree it's a good idea to add can dev to the task list
09:14 <@horms> on the subject of can: i think we should at some point discuss if we want to merge r8a779[34] support even though no board exposes the hw
09:14 < geertu> wsa_: yes
09:14 < geertu> wsa_: and bsp workaround is not sufficient
09:15 < wsa_> horms: that would be applying untested patches to the dtsi?
09:15 <@horms> wsa_: yes
09:16 <@horms> as it stands i have posted the (untested) patches
09:16 < wsa_> i am not strong on this one, but i don't like
09:16 <@horms> so they exist in the archives and people can fish them out
09:16 < wsa_> that's great
09:16 <@horms> i'm inclined to leave them in that state until we can test them: probably forever
09:17 < wsa_> or someone else can test them
09:17 <@horms> right
09:17  * wsa_ stops daydreaming
09:17 < wsa_> so what do you envision for the CAN task?
09:17 <@horms> the other alternative is to merge them. someone can still test them in future. but they may also assume they have already been tested which is (likely) false
09:18 <@horms> well, the above discussion asside. i see two areas of real can work going on
09:18 <@horms> supporting can on r8a7795. and supporting canfd
09:18 < geertu> I guess we already have many device nodes that haven't been tested?
09:18 <@horms> yes, that is the other side of the coin
09:19 <@horms> perhaps not many but surely there are some
09:19 < geertu> Like SCIFs, MSIOFs, MMCs?
09:19 <@horms> perhaps some that we can more reasonably expect to be tested than others
09:19 <@horms> right
09:20 < geertu> At least we try to review additions to .dtsi
09:20 < geertu> which is harder for e.g. all the pinctrl data.
09:20 <@horms> yes, i agree there
09:20 < geertu> (not the pins, but the bits in registers)
09:20 < wsa_> isn't adding r8a7795 support an integration task?
09:21 <@horms> in general the changes are based on similar nodes that are known to work. e.g. for another soc which is documented to work the same way. or other ports on the same soc that are documented to work the same way
09:21 < wsa_> canfd is surely an io task
09:21 <@horms> seems pretty io to me :)
09:22 < wsa_> as a maintainer, I hardly accept untested patches
09:22 <@horms> As far as I can tell Ramesh hopes to get his work merged soon. He was asking me privately about merging his dtsi changes recently
09:22 < geertu> horms: Indeed. Following that logic, adding can nodes for r8a779[34] should be OK
09:22 < wsa_> but I encourage people to send them nonetheless
09:23 < wsa_> which is exactly what happened here
09:23 < wsa_> :)
09:23 <@horms> geertu: yes, i agree with that line of thinking. to be honest i could flip a coin on this one
09:24 < wsa_> morimoto: any news about khim-san?
09:24 < geertu> khim-san = khiem-san?
09:24 < wsa_> oh, sorry
09:24 <@horms> wsa_: there is an argument to be made that the dtsi nodes document the hw. we can see the pdf documentation but most people can't
09:24 < shimoda> wsa_: about thermal or power management things?
09:24 < wsa_> thermal
09:25 < wsa_> there was this idea that he should do the H3 thermal driver?
09:26 < shimoda> morimoto-san and I have a F2F meeting in 25th March. so, we have no update about thermal
09:27 < wsa_> ok, i'll just wait then until you have some news about the task
09:27 < wsa_> until then it keeps assigned to morimoto-san
09:27 < shimoda> thanks
09:28 < wsa_> shimoda: we have the I2C DMA task scheduled for 2016-05-31. Is the date still up-to-date?
09:29 < shimoda> this date is related to the bsp schedule. and i guess it can be changed at 2016-06-30 because
09:30 < shimoda> the bsp schedule is changed :)
09:30 < wsa_> i will do that
09:31 < shimoda> thanks
09:31 < wsa_> i also updated your extcon entry, just saw the public patches:
09:31 < wsa_> USBPHY,v4.7,public,shimoda,add extcon support
09:32 < shimoda> wsa_: yes
09:33 < shimoda> and i will also try to make a prototype of OTG (actually role-swithing) support in this month.
09:33 < wsa_> cool
09:34 < wsa_> I dunno if this makes sense, but IMO this patch could be pointed to the BSP team:
09:34 < wsa_> [PATCH 06/10] mmc: tmio: stop clock when 0Hz is requested
09:34 < wsa_> I couldn't find anything like this in the Gen2/3 BSP
09:35 < wsa_> and it really makes a difference for me. Without, I can't access SanDisk and Samsung cards in UHS modes
09:35 < shimoda> thank you! i will forward this information to the BSP team
09:35 < wsa_> (I have to admit I didn't build the Gen2-BSP kernel yet to actually check)
09:36 < shimoda> wsa_: ahh, if gen3, i guess you should change the DRV value for some UHS cards
09:37 < wsa_> so far, UHS support is Gen2 only
09:37 < wsa_> Gen3 is missing DMA still. But this will be next.
09:37 < wsa_> but I'll keep that in mind!
09:38 < shimoda> wsa_: i see about UHS support.
09:38 < shimoda> about gen3 DMA. I found a hw issue :)
09:39 < wsa_> uh
09:39 < shimoda> i will send an email about the detail to periperi later
09:39 < wsa_> ok
09:39 < wsa_> thanks
09:40 < shimoda> oops, "gen3 DMA" means just SDHI-DMAC, not sys-dmac
09:40 < wsa_> i am definately interested in that one ;)
09:40 < wsa_> so, that's all the points I have
09:40 < wsa_> any more news from your side?
09:41 < morimoto> nothing from Renesas
09:41 < geertu> Not really. Just working with my good ol' friend SCIF again.
09:42 < wsa_> geertu: FIFO or flow control?
09:43 < geertu> wsa_: I'm starting wuith flow control. Will continue with FIFO/
09:44 < wsa_> ok
09:45 < geertu> wsa_: The former implies DT binding updates, so better do that early.
09:45 < wsa_> yes
09:45 < wsa_> let's call it done then
09:46 < wsa_> thanks guys!
09:46 <@horms> thanks!
09:46 < shimoda> thank you!
09:46 < morimoto> wsa_: 1 question. 
09:46 < wsa_> sure
09:47 < morimoto> Do you want invite khiem-san to chat meeting ?
09:47 < morimoto> (not #periperi, but #periperi-io or #renesas-something)
09:48 < wsa_> if he does io-related work, sure
09:48 < morimoto> OK, thanks
09:48 <@horms> fwiw I registered #renesas-soc
09:48 < morimoto> horms: cool ! thanks
09:48 <@horms> feel free to use it as you see fit
09:49 < morimoto> Thanks!
09:49 < morimoto> Thank you IO chat meeting. see you
