+10:55 < pinchartl> This has been addressed by a6cc417d3eee ("drm: rcar-du: Turn LVDS clock
+10:55 < pinchartl> output on/off for DPAD0 output on D3/E3"), present in renesas-drivers.
+10:55 < pinchartl> - drm: rcar-du: Fix dpad signal routing for R8A7799X

+10:55 < pinchartl> Status unclear, but seems part of du/next. Will be investigated further.

+10:55 < pinchartl> https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-bsp.git/commit/?id=d3394635755093f8539acfdbaf932a164ec59533
+10:55 < pinchartl> Tested VGA and HDMI output with kms-test-modeset.py on Laurent's latest

+10:55 < pinchartl> We have already been there with "[PATCH 0/4] drm: rcar-du: Update to SoC

+10:55 < pinchartl> jmondi: anything to discuss then ?
+10:56 < pinchartl> or did you just want to report that ?
+10:56 < jmondi> this should be integrated in Niklas' great work on importing upport tasks in periject
+10:57 < jmondi> apart from that we have clarified off-line most of these tasks
+10:57 < pinchartl> how about we import them, and you send a periject patch on top to address these ?
+10:57 < jmondi> I will investigate "drm: rcar-du: Fix dpad signal routing for R8A7799X"
+10:57 < jmondi> and adv7511 suspend/resume
+10:58 < jmondi> pinchartl: you mean first get Niklas' patch in, and then send patches on top? fine with me
+10:58 < pinchartl> yes
+10:58 < pinchartl> thank you
+10:58 < pinchartl> Topic 3. Discussions
+10:58 < pinchartl> any topic to discuss ?
+10:59 < jmondi> pinchartl: should I wait for more reviews on v4l2-mux before trying to handle the CSI-2 data lane negotiation?
+10:59 < jmondi> or could I send on top of v3?
+10:59 < pinchartl> I think you can send it on top
+10:59 < jmondi> pinchartl: do you plan to review v3? :p
+11:01 < pinchartl> yes I do :-)
+11:01 < jmondi> thanks :)
+11:01 < neg> Any update on the Multimedia development plan work?
+11:01 < jmondi> ah! Sakari just replied to v3 :)
+11:02 < pinchartl> neg: I think at this stage I'd like to have initial feedback from Japan
+11:02 < pinchartl> on Jacopo's proposal
+11:02 < pinchartl> in order to discuss and finalize the plan with the team
+11:02 < pinchartl> before going to Japan
+11:03 < pinchartl> morimoto: damm: do you plan to review the plan proposal sent by Jacopo ?
+11:04 < morimoto> I think we need to. damm-san ?
+11:04 < neg> I was wondering if you had any feedback on that from none mail sources but a face to face meeting coming up might be better. I'm just being curious :-)
+11:05 < pinchartl> damm: have we lost you ? :-)
+11:06 < morimoto> damm: I miss you... so.. much...
+11:07 < jmondi> morimoto: :)
+11:07 < pinchartl> while waiting for Magnus to reply
+11:07 < damm> yes
+11:07 < pinchartl> ah
+11:07 < pinchartl> good timing :-)
+11:07 < pinchartl> was that a "yes, we lost you" ?
+11:08 < damm> pretty much, but morimoto-san and i need time to review
+11:08 < jmondi> morimoto: and no, we very much like you, but we all hate HTML :p
+11:08 < pinchartl> have you had a chance to read Jacopo's e-mail ? do you have any feedback, or could you provide feedback by the end of next week ?
+11:08 < pinchartl> damm: sure, take your time
+11:09 < morimoto> jmondi: hehe :)
+11:09 < pinchartl> let me know if you would like to schedule a HO discussion about it, or if you prefer interacting over e-mai
+11:09 < pinchartl> l
+11:09 < pinchartl> do you think you could provide early feedback by the end of next week ?
+11:11 < damm> let me and morimoto-san check our schedules and see if we can meet
+11:11 < pinchartl> thank you
+11:11 < pinchartl> Topic 4. Additional Tasks for 2019 Q2
+11:11 < pinchartl> it's time to start thinking about those
+11:11 < pinchartl> but there's a question that needs to be answered first
+11:12 < pinchartl> what's the budget situation for Q2 ?
+11:12 < pinchartl> I'm afraid this is again a question for our esteemed Japanese team members
+11:13 < morimoto> It is very serious question
+11:13 < morimoto> Only I can say *so far* is that Q2 is no problem *at this point*
+11:14 < pinchartl> ok
+11:14 < pinchartl> does this mean that we should currently consider that the Q2 budget will be identical to the Q1 budget, and start submitting additional tasks accordingly ?
+11:15 < morimoto> I think so, shimoda-san any comment ?
+11:18 < morimoto> shimoda: I miss you... so.. much... again...
+11:18 < morimoto> what's happen at Japanese network ??
+11:20 < shimoda> sorry for delayed. as morimoto-san mentioned, Q2 budget is OK (same as Q1)
+11:21 < pinchartl> ok
+11:22 < pinchartl> we will then start proposing additional tasks
+11:22 < pinchartl> any other topic to discuss today ? if not, I propose adjourning this meeting
+11:23 < neg> No other topics from me
+11:23 < jmondi> neg: let's sync on updating periject maybe
+11:24 < jmondi> no other topics from me, thank you all
+11:24 < geertu> Woops, will we switch to Summer Time on March 31, or not?
+11:24 < neg> jmondi: I was hoping pinchartl would push my patch once he have looked at it
+11:24 < neg> jmondi: And all changes would go on top of that
+11:24 < jmondi> geertu: for the last time, yes!
+11:24 < pinchartl> neg: I'll review your patch indeed, and we can then push it
+11:25 < pinchartl> I think we can do so offline
+11:26 < neg> sounds good to me
+11:26 < pinchartl> geertu: does it mean that the next meeting will be at 16:00 JST ?
+11:26 < geertu> 08:00 BST / 09:00 CEST / 10:00 EEST /  12:30 IST / 16:00 JST.
+11:26 < geertu> (assuming I don't have it wrong)
+11:27 < pinchartl> that's my understanding too, thanks
+11:27 < pinchartl> multimedia meeting adjourned
+11:27 < pinchartl> thank you all for attending, and have a nice day
