+11:25 < geertu> OK. Then I think we can continue with I/O?
+11:26 < geertu> wsa_: The mic is yours
+11:26 < wsa_> oh, one question: any estimate for SDHI PFC settings for Salvator-XS?
+11:26 < dammsan> geertu: if no further update is needed for additional tasks then i will submit, is that ok?
+11:27 < geertu> wsa_: PFC for I/O devices is typically handled by the person doing the I/O device. Use BSP as a reference.
+11:27 < wsa_> geertu: i see. ok, thanks
+11:27 < geertu> dammsan: Fine for me (I had no feedback from Niklas and Simon?).
+11:27 < dammsan> good, thanks
+11:28 < neg> geertu: I'm sorry my mail that stated I was happy with the draft is stuck in my draft folder for som reasnon. Sorry about that
+11:28 < geertu> neg: No problem, as long as it was a happy response ;)
+11:28 < wsa_> so, welcome to the io meeting
+11:28 < neg> geertu: :-)
+11:29 < wsa_> geertu: you won the sort -R game ;)
+11:30 < geertu> A/C: None
+11:30 < geertu> B: Enable/test MSIOF on Salvator-XS with R-Car H3 ES2.0
+11:30 < geertu> ---EOT---
+11:31 < wsa_> thanks. looking forward to see the outcome of b)
+11:31 < wsa_> uli___: you are next
+11:31 < uli___> 50% of the report for multimedia applies here :) (max9260 i2c host and serdev multiplexing)
+11:32 < uli___> nothing beyond that
+11:32 < wsa_> yup, nice to see that the mux subsystem was nice to use. Peter will be happy about another user :)
+11:33 < uli___> conveniently, it already contains a gpio implementation
+11:33 < wsa_> :)
+11:34 < wsa_> I am next
+11:34 < wsa_> A)      * took part in both MAX9260 & MAX9286 review
+11:34 < wsa_>         * reviewed SDHI cleanup & DMA patches
+11:34 < wsa_>         * researched SCCB compatibility & patched i2c-gpio for it
+11:34 < wsa_>         * rebased and resend SDHI CBSY patch
+11:34 < wsa_>         * upported correct SDHI SD_BUF handling
+11:34 < wsa_>         * sent a patch for correct SDHI CMD12 handling
+11:34 < wsa_>         * additional task preparations
+11:34 < wsa_> B)
+11:34 < wsa_>         * respin I2C core DMA patches
+11:34 < wsa_>         * upport some watchdog patches
+11:34 < wsa_>         * investigate some more SDHI patches for upporting
+11:34 < wsa_>         * create additional tasks
+11:34 < wsa_> C)
+11:34 < wsa_>         * Gen3 SDHI DMA upstreaming issues
+11:34 < wsa_> so, i took a closer look at the SDHI patches from the upport list and tried to recreate the issues
+11:35 < wsa_> but we need to talk about the SDHI Gen3 DMA upstreaming
+11:35 < horms> do you see any BSP patches that may address outstanding issues?
+11:36 < wsa_> DMA wise or in general?
+11:36 < horms> I am assuming one is the tuning issue that Geert reported (or maybe my memory fails me completely)
+11:36 < horms> I meant in general.
+11:36 < horms> I think the BSP does not address our DMA problems
+11:36 < wsa_> yes, there are patches related to tuning, but it is hard to test them
+11:36 < horms> understood. that does not surprise me at all
+11:37 < horms> We can talk about DMA seprately, right?
+11:37 < wsa_> and some I marked "unclear until we get new docs" which we now got!
+11:37 < wsa_> so, thank you for the new documentation!
+11:38 < horms> thanks for the update, no more comments from me for now
+11:38 < wsa_> and i still have this one card which has re-tuning issues. But currently not clear if it is the same issues Geert sees on ALT
+11:39 < geertu> wsa_: it's the ALT in Magnus' farm
+11:39 < wsa_> ok
+11:39 < wsa_> dammsan: requesting access to that one
+11:40 < horms> I also have an Alt if that turns out to be useful, though its also in Japan
+11:40 < dammsan> wsa_: done
+11:41 < wsa_> dammsan: do you prefer to discuss the Gen3 DMA further by mail or by IRC?
+11:41 < wsa_> we started by mail but seems we got interrupted
+11:42 < wsa_> dammsan: thanks!
+11:42 < dammsan> irc may be better
+11:43 < wsa_> can i propose that you, simon, and me keep discussing after the meeting. My availability this afternoon is unclear right now
+11:43 < wsa_> right after the meeting, i meant
+11:44 < dammsan> thats fine with me
+11:45 < horms> I need to be afk for about 2h as of about 1.25h from now. I can, however, re-arange that if really needed.
+11:45 < wsa_> i hope we will have settled before that :)
+11:45 < wsa_> ok, let's continue
+11:45 < wsa_> niklas, please
+11:46 < wsa_> or neg (to activate notifications)
+11:46 < neg> A)
+11:46 < neg>   - No IO work.
+11:46 < neg>   - No IO work planed, other then if there is any overlap while working on the thermal driver.
+11:46 < neg> B)
+11:46 < neg>   - None
+11:46 < neg> C)
+11:46 < neg>   - None
+11:46 < neg> --EOT--
+11:46 < wsa_> yep, "emergency shutdown" was kinda moved to core
+11:47 < wsa_> thanks!
+11:47 < neg> ops cut and paste failed.. but I'm sure you figured it out :-)
+11:47 < wsa_> now shimoda-san, please
+11:47 < shimoda> < I/O >
+11:47 < shimoda> A)
+11:47 < shimoda>  - Debug USB3.0 peripheral driver because BSP team reports some bugs.
+11:48 < shimoda> B)
+11:48 < shimoda>  - Continue to debug the USB3.0 peripheral driver.
+11:48 < shimoda> C)
+11:48 < shimoda>  - Nothing
+11:48 < shimoda> -- EOT --
+11:49 < wsa_> Thank you and good luck with debugging! :)
+11:49 < shimoda> yes :)
+11:49 < wsa_> simon, your turn
+11:49 < horms> A) What have I done since last time:
+11:49 < horms>   - SDHI cleanups accepted
+11:49 < horms>   - Posted SDHI R-Car Gen3 internal DMAC patches v2 + v3
+11:49 < horms> B) What I plan to do till next time:
+11:49 < horms>   - TBD
+11:49 < horms> C) Problems I have currently:
+11:49 < horms>   - Need a plan to handle/not handle SDHI with multiple DMAC implementations
+11:49 < horms> D) Posted/Accepted bugfix patches:
+11:49 < horms>   - None
+11:49 < horms> io/todo:
+11:49 < horms>   - No change
+11:50 < horms> I don't think there are any surprises for you in the above
+11:50 < horms> -- eot --
+11:50 < wsa_> in deed, no surprise ;)
+11:51 < wsa_> morimoto-san, any surprises?
+11:51 < morimoto> A) = B) = C) = NULL, sir. no surprise ;)
+11:51 < morimoto>  
+11:51 < wsa_> :D
+11:51 < wsa_> jmondi: you there?
+11:51 < wsa_> but he already said he had no updates
+11:51 < jmondi> wsa_: yep
+11:51 < jmondi> but no updates for IO
+11:52 < wsa_> ok, thank you all!
+11:52 < wsa_> not much updates, which is no surprise again, since most tasks are usually handled by additional tasks
+11:52 < wsa_> which we don't have this month.
+11:53 < wsa_> so, last chance for questions now
+11:53 < wsa_> otherwise I think we are done
