+09:03 < wsa_> so, let's start the IO meeting and be welcome to that
+09:04 < wsa_> I prepared a summary for the status-updates:
+09:04 < wsa_> A)
+09:04 < wsa_> Geert:
+09:04 < wsa_>  * Working on MSIOF (GPIO/SS1/SS2 slave select),
+09:04 < wsa_>  * Ethernet PHY reset v4 (needed for Salvator-XS resume).
+09:04 < wsa_> Shimoda:
+09:04 < wsa_>  * Got feedback from HW team about HS-USB and investigate the driver how to implement it.
+09:04 < wsa_>  * Investigate runtime PM issue on R-Car Gen3 + USB host controllers.
+09:04 < wsa_>  * Submitted the following patch(es):
+09:04 < wsa_>    * Fix the USB3.0 peripheral driver that has just 5 pipes.
+09:04 < wsa_>  * Merged the "Add PWM dt-binding for r8a77995." into v4.15-rc1.
+09:04 < wsa_> Simon:
+09:04 < wsa_>  * Got some patches accepted
+09:04 < wsa_>  * worked on HS400 support for SDHI
+09:04 < wsa_> Wolfram:
+09:04 < wsa_>  * cured some kind of indigestion, back to full strength now
+09:04 < wsa_>  * implemented various IIC fixes requested by Shimoda-san/
+09:04 < wsa_>    customer team
+09:04 < wsa_>  * improved I2C core bus recovery and implemented recovery for
+09:04 < wsa_>    i2c-rcar on top of that
+09:04 < wsa_>  * discussed SDHI naming scheme with Yamada-san
+09:04 < wsa_>  * reviewed various SDHI patches, mainly from Yamada-san
+09:04 < wsa_>  * quite some stuff got merged after rc1 :)
+09:04 < wsa_>    (IIC fixes, mmc_delay refactoring, I2C DMA series)
+09:04 < wsa_>  * had a look at Uli's D3 patches, but usually Geert is
+09:04 < wsa_>    faster than me ;)
+09:04 < wsa_> Uli:
+09:04 < wsa_> * Sent various Draak integration patches (SYS-DMAC, I2C, SDHI/eMMC, CAN)
+09:04 < wsa_> * resent "R-Car D3 (r8a77995) SDHI (eMMC) integration"
+09:04 < wsa_> B)
+09:04 < wsa_> Geert:
+09:04 < wsa_>  * Continue MSIOF (GPIO/SS1/SS2 slave select, ...),
+09:04 < wsa_>  * Post Ethernet PHY reset v4 after opening of net-next merge window.
+09:04 < wsa_> Shimoda:
+09:04 < wsa_>  * Submit renesas_usbhs driver paches about dequeue handling.
+09:04 < wsa_>  * Continue to investigate the runtime PM issue.
+09:04 < wsa_>  * Investigate USB3.0 role swap issue.
+09:04 < wsa_> Simon:
+09:04 < wsa_>  * Continue work on enabling HS400
+09:04 < wsa_>  * Try to enable SDR-50 and SRR-104 on porter (patch posted, needs testing)
+09:04 < wsa_>  * Upport BSP patch
+09:04 < wsa_>    ed8730231a98 arm64: dts: r8a7795-es1-h3ulcb: Enable UHS-I SDR-104
+09:04 < wsa_> Wolfram:
+09:04 < wsa_>  * write elinux test page for i2c-rcar bus recovery
+09:04 < wsa_>  * upstream I2C core switcher DTS changes
+09:04 < wsa_>  * prepare add. tasks for Q1/2018
+09:05 < wsa_> Uli:
+09:05 < wsa_>  * Send new revision of Draak I2C series.
+09:05 < wsa_> C)
+09:05 < wsa_> none!
+09:05 < wsa_> The notes/questions I have:
+09:06 < wsa_> horms: the SDR104 thing on porter might not working because the issue we have seen on alt is not fixed yet
+09:07 < wsa_> I hope I can have a look after finishing the I2C bus recovery add. task
+09:07 < horms> ahh. so I did test it. and it did not work. but I assumed I was doing something wrong and planned to come back to it.
+09:07 < horms> I also noticed brokenness on Alt yesterday when testing something else (SMP)
+09:07 < wsa_> uh, nice to know
+09:07 < geertu> wsa_: So your assumption is that it's not SoC-specific, but board-specific?
+09:08 < wsa_> geertu: it might even be a driver thing
+09:08 < wsa_> neg found a revert which made it work for him again on Koelsch
+09:08 < wsa_> have to verify this on alt, though
+09:09 < neg> I think the sum of my findings are in '[RFC] mmc: tmio: fix tuning for stubborn cards'
+09:10 < wsa_> horms: in general, how is HS400 coming along? did hell break loose, or is it not as bad? ;)
+09:10 < horms> Its not going great
+09:10 < horms> I backported a bunch of patches.
+09:10 < wsa_> geertu: and well, yes, it is card specific
+09:10 < horms> M3-W seems to not detect devices any more
+09:11 < horms> H3 ES1.0 detects the device but it is slower
+09:11 < horms> I need to make sure I have the latest from uptream as my base, in particular drive strength featues in the driver and DT
+09:11 < Marex> horms: HS400 had issues in uboot too, just FYI, I didnt manage to tune it
+09:12 < horms> My plan was to try to do some triage and report to the ML
+09:12 < geertu> Non-matched PCB traces?
+09:12 < wsa_> drive_strength is in 4.16-rc1
+09:13 < horms> s/15/16/ ?
+09:13 < wsa_> 15
+09:13 < wsa_> heh, sorry
+09:13 < horms> I think I had the driver portion in my most recent branch, as I based it on mmc/next
+09:13 < wsa_> does the BSP work?
+09:13 < horms> But I also think I was missing the DT bit which is in my devel branch (I didn't realise that at the time)
+09:14 < horms> That is a good question. My assumption is yes. I will test.
+09:14 < wsa_> If so, it would rule out HW problems to a high degree
+09:14 < horms> good point
+09:15 < wsa_> so, good luck with that!
+09:16 < wsa_> shimoda: could you kindly provide me with a diff-style update for the io-todo file? I am not sure I can map the patch descriptions from your patches to the task titles 100% correctly :)
+09:17 < horms> Thanks
+09:17 < shimoda> wsa_: sure. I will send it by email later
+09:17 < wsa_> Thank you!
+09:18 < wsa_> So, the final not from me is that I'd like to start looking at add tasks for Q1/2018 slowly.
+09:19 < wsa_> Maybe we can start talking about it in 2 weeks during an all-groups-meeting?
+09:19 < wsa_> I will contact you individually for tasks I might have at hand to negotiate if there is interest
+09:20 < wsa_> And please contact me if you see IO related tasks for you
+09:21 < horms> Two from me, if there is time.
+09:21 < geertu> Sounds good to me
+09:21 < wsa_> horms: nice, can you mail them to me?
+09:22 < horms> Not tasks, questsions for now :)
+09:22 < wsa_> :D
+09:22 < wsa_> then, please
+09:22 < wsa_> fire away now
+09:22 < horms> 1. If you have any small tasks that Kaneko-san might handle in the immediate future feel free to ask
+09:23 < horms> 2. Does v4.15-rc1 work on Salvator-X/H3 ES1.0 or is it just me?
+09:23 < horms> -- fin --
+09:23 < geertu> horms: Last renesas-drivers is supposed to work on that
+09:24 < wsa_> horms: Thanks! I'll check if I have something for Kaneko-san...
+09:24 < horms> geertu: ok, but v4.15-rc1 is broken?
+09:24 < geertu> horms: Not AFAIK
+09:24 < horms> wsa_: thanks. I've been mining the BSP but a lot of what was on my list is now upstream
+09:24 < horms> geertu: ok, I'll assume it was just me
+09:25 < horms> that was all, thanks!
+09:25 < neg> horms: quick question, what is the upstream plan (if any) for 'arm64: dts: r8a7795: Add OPPs table for cpu devices' et. al. ?
+09:25 < horms> ok, that is a good question
+09:26 < wsa_> horms: I'll check the I2C bus recovery on ES1.0, too, later this week. This is based on i2c/for-next which is based on v4.15-rc1. I'll let you know
+09:26 < shimoda> horms: about small tasks, i have some items that issues in v4.14 but bsp patches can resolve it. it is related to suspend to ram
+09:26 < geertu> horms: renesas-drivers with renesas_defconfig boots on Salvator-X/H3 ES1.0
+09:27 < horms> possibly it can go upstream if I clean it up a bit. would that help you? the bigger question is CPUFreq. THere I seem to have some problem getting the Z clk patches working. The fixed /2 divider seems to be a problem for me. I wonder if I could get some advice on how to fix it. Or at least what the propper behaviour to be observied in /sys is. My previous effort seemed to go in the wrong direction :(
+09:27 < horms> shimoda: thanks, they sound like great candidates. Perhaps we can discuss on the periperi ML?
+09:27 < geertu> horms: With the fix from the BSP, Z and Z2 are correct for me on H3 ES2.0 and M3-W
+09:27 < wsa_> okay, we entered the core realm already, me thinks
+09:27 < horms> Or here, a bit later, if you like
+09:27  * wsa_ throws the mic to Geert
+09:28  * geertu misses
+09:28 < wsa_> thank you all for the IO meeting!
