10:51 <DarkNeutrino> apritzel: So i ran DTB check and its complaining about missing interrupt properties in axp313a node. So i gave it interrupt 0 and cells 1 but its warning me about the size thats its 4 expected to be a multiple of 12. The actual interrupt isnt wired up so i dont exactly know what to give it. here is the axp313a node https://pastebin.com/kVyNPtnR and the SoC is H616.

10:51 <DarkNeutrino> If anyone else knows i would love to hear ideas :)

11:32 <apritzel> DarkNeutrino: the interrupt property format has to match the expectation of the interrupt parent, which by default is the GIC directly (see interrupt-parent in the root node of h616.dtsi)

11:32 <DarkNeutrino> yep i know that. But i have no clue what to give it. Just 0 0 0 ?

11:33 <DarkNeutrino> H6 and A64 which have similar setup to us have r_intc node. I dont see that on H616

11:33 <apritzel> because there is no r_intc on the H616

11:34 <DarkNeutrino> Exactly :)

11:34 <apritzel> is the PMIC's IRQ pin is not connected, you actually shouldn't specify an interrupt at all

11:34 <DarkNeutrino> OK but then DTB check yells at me

11:35 <DarkNeutrino> Which folks wont like when they will be checking the patch

11:35 <apritzel> I have the feeling we should make it optional for all PMICs, since it's not really a PMIC property, but a board designer decision

11:35 <apritzel> yes, I agree

11:35 <apritzel> so for the OrangePi Zero3 the IRQ pin is connected to an GPIO

11:37 <apritzel> DarkNeutrino: see here for how that looks like: https://lore.kernel.org/linux-arm-kernel/20230731011725.7228-4-andre.przywara@arm.com/#Z31allwinner:sun50i-h618-orangepi-zero3.dts

11:37 <DarkNeutrino> YEP when its connected to GPIO it makes sense.

11:38 <DarkNeutrino> https://github.com/bigtreetech/CB1/blob/master/Hardware/BIGTREETECH_CB1_V22_220812_SCH.pdf

11:38 <apritzel> I am afraid this requires another patch to make the interrupt property optional

11:38 <DarkNeutrino> :(

11:38 <apritzel> ah, OK, it's only a test point

11:39 <DarkNeutrino> yea

11:40 <DarkNeutrino> I got hired by BTT/Biqu3d so i have some input on the hardware design now so i will try to make sure things like this dont happen. But yea not perfect

11:40 <DarkNeutrino> on future SBCs that is

11:41 <apritzel> arguable the IRQ functional is somewhat optional for PMICs in general, and for this small one in particular

11:41 <apritzel> functionality*

11:42 <DarkNeutrino> Generally yea.

11:42 <apritzel> so I think it's OKish to not connect it, but if there is a spare GPIO, it also doesn't hurt, and gives you the ability to get notified about overheating or undervoltage and such

11:43 <DarkNeutrino> There are many spare GPIOs afaik.

11:44 <DarkNeutrino> So yea it would be nice to have it connected in the first place

11:45 <apritzel> but it's too late for that anyway, and from a technical point of view the IRQ *is* optional, so the binding should reflect that

11:45 <apritzel> I will make a patch, let's see what people say

11:46 <DarkNeutrino> CC me in it please. At my somainline email and also specify my work one (martin@biqu3d.com)

11:48 <DarkNeutrino> When you send the patch i will be able to send my DT and specify that it depends on your patch :)

11:48 <gamiee> DarkNeutrino: offtopic, but is BIQU 3D from BTT?

11:49 <DarkNeutrino> BTT is from biqu :)

11:50 <DarkNeutrino> Biqu makes 3d printers as complete kits and BTT makes the accesories like the controller boards and etc :)

12:00 <gamiee> oooh! Makes sense. Thanks for explaining

12:01 <DarkNeutrino> No worries :)

12:11 <gamiee> DarkNeutrino: I sent you a DM if you don't mind from my another IRC account (since this is bridge only, no PMs).

12:12 <DarkNeutrino> I tried to reply to you in DMs but i cant.

14:40 <buZz> BTT is pretty cool

14:40 <buZz> btw, if you wnt to talk more about 3d printers, maybe checkout #reprap ?

14:40 <buZz> dark<tab> oh nevermind

14:40 <buZz> not a irc user :D

15:00 <warpme> apritzel : do you know what uboot ver. i need to test https://lore.kernel.org/u-boot/20230729111331.173768-2-iuncuim@gmail.com/ (lpddr4 on h618)?

15:30 <apritzel> warpme: I applied it on top of latest mainline

15:31 <warpme> ah ok. I tried on 2023.10 and many hunks failed. lety me try on current head

15:31 <apritzel> but it didn't really work on the OrangePi Zero3, at least not with the parameters I harvested from the boot0 found on the SPI flash

15:32 <apritzel> 2023.10? You mean -rc1? because that should actually work

15:32 <warpme> oh - thx for info!. In fact i'm playing exactly with zero3

15:33 <warpme> oops - sorry - i was trying on 2023.07.02

15:33 <apritzel> I am wading through the code, comparing it with OrangePi's version here: https://github.com/orangepi-xunlong/u-boot-orangepi/commit/e5052869f784ffa16df7f1f07cbc782f82405479

15:33 <DarkNeutrino> buZz i was off for a sec :)

15:34 <buZz> in that channel are quite some BTT users anyway ;)

15:34 <apritzel> warpme: yeah, 2023.07 won't work, you need the recently merged LPDDR3 support for the hunks to match (though actual LPDDR3 support is of course orthogonal)

15:34 <buZz> oh, on libera.chat btw, not on OFTC

15:35 <apritzel> warpme: I am halfway through trying to deduce the right parameters from the OrangePi code, that's just proper mindboggling

15:36 <warpme> apritzel : re lpddr3: is this with jernej's parametrized dram support?

15:37 <apritzel> warpme: yes, that's why the OrangePi drop (based on 2021.07) is quite different: we gained parameters and LPDDR3 meanwhile

15:37 <apritzel> warpme: I am quite confident I will get the OPiZero3 LPDDR4 to work this week, then will reply to junari's patch and propose OPiZero3 U-Boot support on top

15:37 <warpme> oh thats qll

15:38 <apritzel> meanwhile you can harvest the firmware from Armbian (that's what I did for testing)

15:38 <warpme> i need to run for 2..3h will be back at evening

15:45 <apritzel> warpme: (for when you come back): I think that's the link: https://github.com/leeboby/opizero3-uboot-dtb/raw/main/u-boot-sunxi-with-spl-opizero3-4gb.bin

15:45 <DarkNeutrino> buZz yea i will skip for now. I have enough 3D printers myself at home hehe

15:46 <apritzel> warpme: and what DRAM size does your board have? I went for 4GB, of course, but it would be great to test the 1/2GB and more curiously the 1.5GB version as well

15:46 <buZz> DarkNeutrino: np, it was just for your occupational interest

15:55 <DarkNeutrino> I will jump in ofc from time to time :)

16:19 <DarkNeutrino> Oh i just noticed. Ddr4 on h616. Heck yea.

17:23 <junari> apritzel: can you post somewhere actual dram_para and register dump? I can look too

17:27 <warpme> apritzel: it is 4G variant
