+10:07 < geertu> Thank you, Niklas
+10:07 < geertu> Next is Jacopo
+10:07 < jmondi> let me retreive the email I sent
+10:07 < jmondi> A)
+10:08 < jmondi> - v4 of RZ pin controller
+10:08 < jmondi> - RZ clock tested and enabled on Genmai
+10:08 < jmondi> - tested pin controller driver with DT overlays
+10:08 < jmondi> - working on using JTAG debugger on Genmai
+10:09 < geertu> So it's v4, not v5?
+10:09 < jmondi> B) = C) = D) = NULL
+10:09 < jmondi> geertu: I wrote v5 in the email, but I got confused
+10:09 < jmondi> it's v4
+10:09 < jmondi> -- eot --
+10:10 < geertu> Thank you, Jacopo.
+10:10 < geertu> Next is Laurent. I assume he's just lurking around?
+10:10 < pinchartl> correct
+10:10 < pinchartl> I have no core task
+10:10 < geertu> Next is Morimoto-san
+10:11 < morimoto> A) What have I done since last time
+10:11 < morimoto> I posted "SYS-DMAC + 40bit + descriptor mode" patch to ML, and it was accepted.
+10:11 < morimoto> I created/fixed periupport script. I hope it is now useful :)

+10:15 < shimoda> -- EOT --
+10:15 < geertu> Thank you, Shimoda-san
+10:15 < geertu> Simon is excused, arriving in Kobe. His ABCD are:
+10:15 < geertu> A) No Core task at this time
+10:15 < geertu> B) No Core task at this time
+10:15 < geertu> C) Selecting patches for upporting
+10:15 < geertu> D) None
+10:16 < geertu> Marek is also excused, he let me know the following:
+10:16 < geertu> A) BD9571 MFD, GPIO, and regulator drivers
+10:16 < geertu> B) Publish BD9571 drivers
+10:16 < geertu> It's been a while I saw Khiem and Uli
+10:17 < horms> I assume Khiem has been reassigned
+10:18 < geertu> Probably
+10:19 < geertu> And his email routed to (the Windows equivalent of) /dev/null
+10:19 < geertu> Well, that went smooth!
+10:19 < horms> likely
+10:19 < geertu> Any other topics to discuss?
+10:19 < dammsan> at least it is translated to CR LR before going into NULL
+10:19  * horms has arrived in Kobe
+10:19 -!- horms [~horms@g1-27-253-251-9.bmobile.ne.jp] has quit [Quit: Leaving]
+10:19 < geertu> Perhaps periupport?
+10:20 < geertu> I plan to go over the core related patches, as I believe several of them were upstreamed in some form
+10:21 < geertu> I already did that for the patches that had identical patch IDs in upstream
+10:22 < morimoto> geertu: I posted periupport patch again. I hope you can accept it
+10:23 < geertu> morimoto: Thank you. But that will probably happen only next week.
+10:24 < morimoto> OK, np
+10:25 < geertu> Any other topics to discuss?
+10:26 < geertu> For next meeting, I propose Tuesday, April 25, 08:00 GMT / 10:00 CEST / 11:00 EEST / 17:00 JST
+10:26 < neg> I have a question about JTAG :-)
+10:26 < geertu> neg: shoot!
+10:26 < jmondi> I have -many- questions about JTAG
+10:26 < jmondi> (joking, go on neg)
+10:27 < geertu> neg: Machine gun questions?
+10:27 < geertu> sorry, jmondi: Machine gun questions?
+10:27 < neg> A while back I got my Flyswatter 2 and managed to find and modify some OpenOCD config files to get ut running on Gen2. If those could be tested on more boards then my Koelsch I think we could (re)try to get them picked up in upstream OpenOCD. Do you think there would be value in this?
+10:28 < neg> I posted the configs at https://git.ragnatech.se/renesas-jtag/ and intend to write up elinux wiki page, I assume the SW settings to enable JTAG are OK to describe there as well?
+10:30 < geertu> Cool!
+10:30 < geertu> I only have
+10:30 < geertu> source [find interface/ftdi/flyswatter2.cfg]
+10:30 < geertu> reset_config trst_and_srst
+10:30 < geertu> jtag_rclk 8
+10:30 < neg> last question is aimed at Morimoto-san :-)
+10:30 < geertu> (most from Magnus, IIRC) so I never got that far...
+10:31 < jmondi> neg: I will send you patches to use OpenOCD+Flyswatter on RZ as well :)
+10:32 < neg> jmondi: nice :-)
+10:35 < kbingham> neg: I guess you haven't looked at G3 yet :)
+10:36 < neg> kbingham: thats right :-)
+10:36  * geertu assumes kbingham is not talking about SH7367 (SH-Mobile G3)
+10:37 < kbingham> geertu: Well, maybe I was ... :D
+10:37 < geertu> Every spelling mistake is a different SoC ;-)
+10:37  * morimoto geertu solved my confusion
+10:37 < geertu> morimoto: cs2000?
+10:37 < morimoto> No, about G3 :)
+10:37  * kbingham coughs : Gen 3
+10:37 < geertu> kbingham: R-Car Gen3?
+10:39  * morimoto I think neg's "last question" is not yet coming ?
+10:39 < neg> morimoto: sry, my question was if it's OK to mention wich SW on the board you need to flip to enable JTAG, is this OK to mention on the elinux wiki?
+10:40 < neg> for Gen2 that is
+10:40 < morimoto> Ahh, OK. I think it is no problem
+10:41 < neg> OK thanks
+10:42 < neg> So I will let them stew in the reop and write a elinux page. If you try them out on Alt or Lager please let me know if all works I can resubmit them to OpenOCD and se what happens
+10:43 < neg> that was all from me, thanks
+10:46 < geertu> neg: Have you tried JTAG on the KZM9D?
+10:46 -!- dammsan [~dammsan@s214090.ppp.asahi-net.or.jp] has quit [Remote host closed the connection]
+10:46 < geertu> It may help to solve the SMP issue
+10:46 < neg> geertu: no not yet, lurking in the back of my head tho
+10:47 < neg> geertu: but I think Magnus once told me some special magic where needed to get it working
+10:48 < geertu> OK
+10:49 < geertu> Then I think we are finished?
+10:49 < geertu> Thanks for joining, and have a nice continued day!
+10:50 < shimoda> thank you!
+10:50 < neg> I have nothing further, and the 25th works fine for me
+10:50 < neg> thanks all
+10:50 < jmondi> 25th is kind of bad for me
+10:50 < jmondi> national holiday here and I don't plan to be home...
+10:51 < jmondi> sorry I forgot to tell
+10:52 < morimoto> 25th is OK for me too
+10:52 < morimoto> thanks
+11:01 < morimoto> geertu: are you still here ?
+11:01 < morimoto> I want to ask you about cs2000
+11:07 < geertu> morimoto: yes, still here
+11:07 < morimoto> what does your "a mux clock driver with three parents" ?
+11:08 < geertu> morimoto: it's a very simple driver where you can select between 3 parents
+11:08 < morimoto> How to select it ? by DT ?
+11:08 < geertu> By clk_ops.set_parent()
+11:09 < geertu> or .determine_rate(), which selects the best parent for the requested rate
+11:09 < geertu> drivers/clk/clk-mux.c
+11:09 < morimoto> Ahh..
+11:10 < morimoto> OK, thanks. I will check clk-mux.c
+11:17 < morimoto> 1 question again. Who/How to select parent clock of .set_parent() ?
+11:17 < morimoto> This AUX_OUT usage is board specific
+11:18 < morimoto> Ahh, OK, I understand
+11:18 < morimoto> Thanks
