Morimoto-san +09:18 < geertu> Laurent seems to be away +09:18 < geertu> Next is myself +09:18 < geertu> A) Worked with Simon and Arnd to get our pull requests for arm-soc accepted. +09:18 < geertu> Sent pull requests for soc_device_match() and RZ/G clock definitions +09:18 < geertu> B) Coerce Simon into taking all MODEMR related patches +09:18 < geertu> 2017Q1 additional tasks +09:19 < geertu> C) What's wrong with the IPMMU? (more like a retorical quesiton) +09:19 < geertu> EOT +09:19 < horms> a) thanks! +09:19 < horms> b) happy to negotiate :) +09:19 < geertu> From the emails, looks like the HW team is investigating the IPMMU? +09:20 < geertu> Last (present) is Jacopo +09:21 < jmondi> A) PFC patches for Gyro-ADC: v3 in review +09:21 < jmondi> Enabled and tested MAX11100 ADC on genmai board. RFC patches sent out +09:22 < jmondi> B) Not sure is a core task, but I should write an IIO driver for that same ADC this week +09:22 < jmondi> C) none +09:22 < jmondi> that's all from me +09:22 < jmondi> -- end -- +09:22 < shimoda> geertu: yes, the HW team is investigating the IPMMU now. +09:23 < geertu> IIO drivers are indeed not core, but I/O. I don't know if Wolfram plans an I/O chat later this week. +09:23 < horms> jmondi: please consider patches to enable options in defconfigs if appropriate +09:23 < geertu> Thank Jacopo +09:23 < geertu> horms: The MAX11100 ADC is an add-on, not an on-board device +09:24 < jmondi> horms: for ADC you mean? +09:24 < jmondi> yes, it's temporary connected to one of Genmai's expansion header +09:24 < horms> It was just a general request. I'd need to look at the patches more closely to make a specific request regarding them. +09:25 < jmondi> need to sync with Magnus because we'll use another board, but it will remain connected to some expansion connector I guess +09:25 < horms> Ok +09:25 < horms> understood +09:25 < horms> my comment is probably not relevant in that case +09:25 < jmondi> horms: it may be for future! thanks anyway :) +09:26 < geertu> Topic 2. Proposal from BSP team about PFC I2C ch0, 3 and 5. +09:26 < geertu> Submitted by Shimoda-san +09:27 < shimoda> yes, should i explain? +09:27 < geertu> Yes please. +09:27 < neg> shimoda: yes please +09:28 < shimoda> I sent an email. BSP team would like to set the such pins via PFC driver +09:29 < shimoda> the pins spec differs than other pins. so bsp team think that the PFC driver should have other way +09:29 < geertu> IIUIC, multiple functions can be muxed to the i2c pins, but they cannot be used for GPIO? +09:30 < shimoda> geertu: let me check... +09:30 < geertu> It uses PIN_NUMBER('B', 11) +09:32 < geertu> But it also touches avb, hscif, msiof, pwm, sdhi +09:33 < geertu> Does it mean those functions are mutually exclusive with the i2c function, although they use different pins? +09:33 < geertu> And is this ES1.0 or ES2.0? +09:35 < shimoda> geertu: i don't know this is ro es1.0 or es2.0 +09:37 < shimoda> about this mod_sel, as you said, they are muxed pins. +09:39 < shimoda> and these i2c pins cannot bd used for GPIO +09:40 < shimoda> this patch reuses POC/DRVCTRL register setting thing +09:41 < shimoda> BSP team would like to know this policy is good or not +09:41 < geertu> Ah, it's for e.g. "Phisically muxed with AVB_AVTP_MATCH_A" inside some floating comment box in (preliminary)CSD15-676_R-CarH3_pinfunction(Rev0p290)_customer.xlsx, which you cannot search for using LibreOffice +09:44 < geertu> According to that xlsx, it uses the same pin numbers as the "Phisically muxed" pins, but in a different row of the sheet. +09:45 < neg> It's pinmux for none-GPIO pins right? +09:45 < geertu> Can't we just use the corresponding RCAR_GP_PIN()? +09:46 < geertu> E.g. SCL0 is SoC pin AA33, SiP pin C29 +09:47 < geertu> But SD1_CD is also AA33 / C29, and GP3_14 +09:48 < geertu> so we could use RCAR_GP_PIN(3, 14) instead of PIN_NUMBER('C', 29)? +09:48 < geertu> What am I missing? +09:49 < geertu> I think this needs more clarificiation / investigation, offline. +09:50 < geertu> shimoda-san: Do you agree? +09:51 < shimoda> geertu: about red line in the xlsx file, it seems your comment is match, i will ask hw team or/and bsp team +09:51 < shimoda> and offline, it's nice to me :) +09:51 < shimoda> s/red line/red rectangles/ +09:52 < neg> yes, I think if there are a RCAR_GP_PIN() for that pin it should be used, or I'm also missing something +09:52 < geertu> It depends on what "Phisically muxed" really means +09:54 < geertu> (in gnumeric, it shows a black rectangle. I also cannot search for its contents, but I can move (not edit) it ;-) +09:54 < geertu> Let's continue +09:54 < geertu> Topic 3. FOSDEM+core confirmation: who? +09:55 < geertu> So it seems like Morimoto-san will miss the rabbits, and will go to trump(et)land instead ;-) +09:55 < geertu> Who's still planning to attend FOSDEM, and a core meeting on Friday before? +09:55 < geertu> +1 Geert +09:56 < neg> I will go to FOSDEM but have yet to book my tickets +09:57 < neg> (and attend the core meeting on Friday ofc) +09:57 < horms> If there is a Core meeting then I expect to be there +09:57 < horms> I may also come up with other reasons to be there, but that is the main one at this time +09:57 < jmondi> I'll be at fosdem. Hopefully I'll still have a reason to join these meetings :) +09:59 < morimoto> Please enjoy rabbits in FOSDEM :) +10:00 < geertu> I prepared rabbit two weeks ago +10:01 < geertu> I think we're finished, unless someone has still something to add? +10:01 < neg> are there any periperi plans for ELC timing since Morimoto-san will not join at FOSDEM? I have not made any plans for ELC but if I'm to go I think it's best to book soon :-) +10:02 < geertu> deadline for proposals is this Saturday. +10:02 < geertu> I don't plan to go to ELC this time. +10:03 < neg> ok sorry for proloning the meeting just wanted to check so I don't have to buy expensive tickets later on +10:03 < horms> I am considering going but so far have no plans +10:04 < geertu> neg: the tickets may become cheaper after the inauguration of the next president ;-) +10:06 < neg> geertu: haha yes and his inauguration is at end of Jan so maybe the riots in portland have settled down by ELC +10:08 < geertu> Thanks for joining, and have a nice continued day! -- cgit v1.2.3
