+09:03 < wsa> so, let's start the IO meeting
+09:03 < wsa> hi Magnus!
+09:04 < damm> hi wsa!
+09:04 < wsa> first of all, if someone of JapaPERI could tell Morimoto-san all the best wishes for his well-being from the IO group, this would be very kind and awesome!
+09:04 < Marex> +1
+09:05 < kbingham> Morning all!
+09:05 < wsa> okay, here are the status updates:
+09:05 < wsa> A - what have I done since last time
+09:05 < wsa> ------------------------------------
+09:05 < wsa> Geert
+09:05 < wsa> : enabled (H)SCIF on R-Car M3-W+, developed a test to check SCIF status/data
+09:05 < wsa>   ordering and tested various variants, DT binding doc conversion to
+09:05 < wsa>   json-schema: sh-sci, rspi, cmt, tmu
+09:05 < wsa> Shimoda-san
+09:05 < wsa> : discussed with internal Renesas members about supporting eMMC v5.1 features
+09:05 < wsa>   for R-Car Gen4, reviewed PCIe endpoint support
+09:05 < wsa> Ulrich
+09:05 < wsa> : looked into issue with WDT clock still being disabled even though it is
+09:05 < wsa>   declared as ignore-unused
+09:05 < wsa> Wolfram
+09:05 < wsa> : had a look at the series about blocked I2C devices, sent out the last chunk
+09:05 < wsa>   of I2C API conversion patches, updated and sent "best TAP if all are good"
+09:05 < wsa>   for SDHI, worked on upporting BSP patch to avoid BAD_TAPs with SDHI,
+09:05 < wsa>   refactored FW parsing of i2c timings, reviewed patches for i2c core,
+09:05 < wsa>   assisted MM guys with virtual I2C devices and busses
+09:05 < wsa> B - what I want to do until next time
+09:05 < wsa> -------------------------------------
+09:05 < wsa> Geert
+09:05 < wsa> : wants to follow up json-schema conversions, and check for more RSPI
+09:05 < wsa>   improvements
+09:05 < wsa> Niklas
+09:05 < wsa> : wants to keep looking what is missing upstream for thermal drivers
+09:05 < wsa> Shimoda-san
+09:05 < wsa> : wants to add more device nodes to R8A7796, continue to read the Ethernet HW
+09:05 < wsa>   IP document, test SDHI TAP patches from Wolfram, continue to collect
+09:05 < wsa>   information about "R-Car Gen4" hardware IPs, update renesas_sdhi_sys_dmac
+09:05 < wsa>   patches
+09:05 < wsa> Ulrich
+09:05 < wsa> : wants to post new ignore-unused clock series, implement xfer_atomic callback
+09:05 < wsa>   for i2c drivers
+09:05 < wsa> Wolfram
+09:05 < wsa> : wants to get the series about blocked I2C devices in DT applied, send out
+09:05 < wsa>   the SDHI patch to avoid bad TAPs, test Ulf's MMC core patches
+09:06 < wsa> feel free to ask or comment if things are unclear
+09:07 < wsa> other than that, I'd like to check if my assumptions about your load match reality
+09:07 < wsa> geertu: some IO tasks once in a while, but otherwise busy enough with core work?
+09:08 < wsa> Marex: busy enough with U-Boot and ATF stuff?
+09:08 < Marex> wsa: pretty much, why ?
+09:09 < wsa> neg: busy with MM stuff plus some love for the thermal drivers? :)
+09:09 < Marex> wsa: U-Boot release is just around the corner
+09:09 < neg> yes ;-)
+09:09 < geertu> wsa: I pick up what comes in ;-)
+09:09 < wsa> Marex: just want to make sure no one is running out of tasks without me noticing
+09:09 < Marex> wsa: I think I'm good
+09:10 < wsa> Marex: BTW can you resend this PCIe patch from ex-ARM guy Andrew? It is still not in -next, maybe a resend helps
+09:11 < Marex> wsa: I have another PCIe patch to which I got no reply too
+09:11 < Marex> wsa: seems PCIe subsystem is like that
+09:11 < wsa> shimoda: probably overloaded with tasks :)
+09:12 < wsa> Marex: it won't hurt much. And maybe [PATCH] looks better than [RFC]
+09:12 < wsa> uli_: I think you have enough tasks for now?
+09:12 < shimoda> wsa: yes, but I'm OK :)
+09:13 < wsa> wsa: you won't be bored, right?
+09:13 < uli_> wsa: for now i'm ok
+09:13 < wsa> wsa: sadly not :D
+09:13 < geertu> The merge window is open, so some people may not review patches
+09:14 < wsa> okay, thanks guys. Seems my assumptions haven't been far off...
+09:14 < Marex> wsa: sure, just telling you how things are over there
+09:14 < wsa> Marex: yeah, I noticed meanwhile that PCIe is even slower than I2C ;)
+09:15 < wsa> One question about M3-W+: if this patch is upstream ("dt-bindings: mmc: renesas_sdhi: Document r8a77961 support"), does it mean eMMC access has been tested?
+09:16 < wsa> and M3-W+ is ES3.0 not ES1.3? (why can't i memorize this??)
+09:17 < wsa> geertu: ?
+09:17 < geertu> wsa: Yes, accessing eMMC on M3-W+ works
+09:18 < geertu> i.e. I could read from it
+09:19 < patersonc> wsa: and M3-W+ is v3.0
+09:19 < geertu> Got a Tested-by from erosca, too
+09:21 < wsa> thanks. I need to upport more SDHI quirk handling, so I need to take care about ES versions
+09:22 < geertu> wsa: Feel free to do more extensive testing on the board in Magnus' farm
+09:22 < wsa> geertu: this is likely to happen
+09:22 < wsa> so, this is it from my side
+09:22 < wsa> anything from yours?
+09:23 < wsa> especially shimoda or damm?
+09:23 < shimoda> nothing from my side
+09:23 < kbingham> wsa, geertu, I wondered if you have any further comment on https://lore.kernel.org/lkml/20190710193918.31135-1-kieran.bingham+renesas@ideasonboard.com/ ... (Extending file2alias to simplify i2c device table entries when mixed with both an OF and I2C table?) ... I think the discussion headed towards a macro called I2C_OF_MODULE_DEVICE_TABLE() to simplify things. Any thoughts? Should I just 'do it'?
+09:24 < damm> same here
+09:24 < kbingham> (question is mostly targeted at Woflram, as Yamada-san suggested that any change there would go through wsa's tree :-) )
+09:25 < wsa> Is it hard to do? Usually it is easier to talk about code
+09:25 < kbingham> I don't think it's hard, my question is mostly about policy I think :)
+09:26 < wsa> I'd need to dive into that topic again otherwise to make useful comments :)
+09:26 < kbingham> Ok :)
+09:27 < kbingham> I'll try and prepare a v2 update then :)
+09:27 < wsa> good, looking forward to it
+09:28 < kbingham> Ok that's all from me then :P)
+09:28 < wsa> last order for IO, then you have to move to the core-pub
+09:28 < geertu> the pub is closed
+09:28 < geertu> (except in Sweden?)
+09:29 < wsa> then thanks for this meeting!
