+09:02 < wsa> okay, then let's start the IO meeting
+09:02 < wsa> welcome everyone!
+09:02 < wsa> here are the status updates:
+09:02 < wsa> Status updates
+09:02 < wsa> ==============
+09:02 < wsa> A - what have I done since last time
+09:02 < wsa> ------------------------------------
+09:02 < wsa> Geert
+09:02 < wsa> : fixed st1232 touchscreen regression on armadillo800ev, investigated Lager reboot crash reported by Wolfram (RFCs sent), tested MSIOF with SYS-DMAC on R-Car V3U and reposted patches, advertised MSIOF min/max speed limits and actual transfer speed to SPI core, reviewed R-Car V3U patches
+09:02 < wsa> Shimoda-san
+09:02 < wsa> : submitted patches to detect data timeouts on SDHI, investigated RPC-IF driver issues with BSP team
+09:02 < wsa> Wolfram
+09:02 < wsa> : enabled and tested V3U IO devices: WDT, I2C, RAVB, SDHI, HSCIF, implemented V3U quirk for I2C driver and improved Gen2 quirk handling, tested and reviewed V3U PFC & GPIO patches, improved logic analyzer and got a working prototype, reworked and sent out WDT patch to fix scheduling while atomic, sent first preparation patches for better RECV_LEN support so we can enable it then on
+09:02 < wsa>  i2c-rcar, started discussing add. tasks for Q1
+09:02 < wsa> B - what I want to do until next time
+09:02 < wsa> -------------------------------------
+09:02 < wsa> Geert
+09:02 < wsa> : wants to fix PHY Runtime PM in SH-ETH and EtherAVB driver
+09:02 < wsa> Niklas
+09:02 < wsa> : wants to figure out number of TSC nodes on V3U
+09:02 < wsa> Shimoda-san
+09:02 < wsa> : wants to collect more information about R-Car Gen3e, continue to develop R-Car S4 Ethernet driver, and continue to investigate SDHI driver's issues
+09:02 < wsa> Ulrich
+09:02 < wsa> : wants to test and send atomic xfers for i2c-rcar
+09:02 < wsa> Wolfram
+09:02 < wsa> : wants to send updates of the V3U enablement patches, finalize GPIO logic analyzer, continue to to work on RECV_LEN patches, pick up SDHI work again
+09:02 < wsa> C - problems I currently have
+09:02 < wsa> -----------------------------
+09:02 < wsa> Shimoda-san
+09:02 < wsa> : couldn't get further Gen3e information
+09:02 < wsa> Wolfram
+09:02 < wsa> : needs wired pins on the connectors of the V3U Falcon to test PWM and TPU
+09:03 -!- uli___ [~uli@55d468c5.access.ecotel.net] has joined #periperi
+09:04 < wsa> geertu: good that I had a non-standard .config for Lager, that is a highly interesting outcome what you found out with the ethernet phys there
+09:04 < geertu> wsa: Indeed.
+09:04 < geertu> wsa: Tried the same on AVB?
+09:05 < geertu> Ah no, won't crash as invalid access doesn't cause crashes on arm64.
+09:05 < wsa> shimoday: so, it seems to me that I can test RPC-IF with an upstream kernel then (not importing BSP patches)
+09:05 < wsa> geertu: nope, didn't try, but noticed that you found that out
+09:05 < shimoday> wsa: i think so
+09:06 < geertu> wsa: After fixing the issues in the upstream driver, as pointed out by Shimoda-san?
+09:07 < wsa> wasn't it the BSP driver which is broken?
+09:07 < shimoday> geertu: oops, as you said, fixing the issue at first is better
+09:08 < shimoday> because upstream code seems to have other issues
+09:08 < geertu> wsa: Continue reading below "By the way, according to the wrong BSP commit 3612986e5109, the RPC-IF driver seems to have some issues."
+09:08 < wsa> ah, that
+09:08 < wsa> ok
+09:10 < wsa> so, about wiring on V3U
+09:10 < wsa> from what I understand, we'd need extra thin jumper wires?
+09:10 < wsa> but I couldn't track any
+09:12 < geertu> wsa: You mean GPIO CN, with 1.27mm pitch?
+09:12 < wsa> yes
+09:13 < geertu> Use an adapter cable from 1.27mm to 2.54mm pitch? Cfr. JTAG
+09:15 < geertu> Make one yourself, if you cannot find one? 2 IDC connectors + 1.27mm ribbon cable
+09:15 < wsa> hmm, i found hw adapters but no cable
+09:16 < wsa> maybe jtag will give me better search results
+09:16 < wsa> it is not so much for me but for Magnus board farm :)
+09:17 < geertu> damm: BTW, does your Falcon have the ether subboard?
+09:17 < damm> yep
+09:17 < wsa> I'll check
+09:17 < wsa> (adapter cables)
+09:19 < wsa> geertu: AFAIU the next version of renesas-drivers should have the V3U PFC and GPIO patches, or?
+09:19 < geertu> wsa: The previous one
+09:19 < geertu> had v2
+09:20 < geertu> actually the one before, too
+09:21 < wsa> yes
+09:22 < wsa> sorry, my question was not precise
+09:23 < wsa> the patches are all good to go, so they will come into the nex ren-drivers release via -next and not seperate topic branches, or?
+09:23 < geertu> correct
+09:24 < wsa> great news!
+09:24 < wsa> so, discussion topics from your side?
+09:26 < wsa> okay, then it seems we can move to the core meeting
+09:26 < wsa> thank you everyone!
