12:34 <lumag> konradybcio, do you know if there is a fw dump of any sm6150 phone? Or anybody having it? I'm intetested in the hexdump of venus.b01, first line of the dump

12:34 <lumag> z3ntu, aka_[m] ^^

12:34 <lumag> calebccff, ^^

12:36 <z3ntu> lumag: https://github.com/goshhhy/motorola-def-firmware/tree/master/files ?

12:36 <z3ntu> this device should be Qualcomm Snapdragon 675 (SM6150)

12:41 <lumag> z3ntu, thanks!

16:59 <z3ntu> lumag: Do you know how msm8974 does it with the one USB controller and two PHYs? Can you enable both USB "ports" and make them functional at the same time? That seems to work downstream (or at least haven't heard anything different). At least upstream I don't see both phys being enabled at the same time

17:01 <z3ntu> E.g. on Fairphone 2 the main USB HS1 is connected to the micro USB connector on the phone, while USB HS2 is connected to some pogo pins on the back, and to my knowledge both work, not 100% sure at the same time but at least it's dynamically switching at the very least. minecrell or maybe you have an idea?

17:04 <z3ntu> also ref: https://github.com/msm8974-mainline/linux/issues/21

17:29 <konradybcio> i think 8974 has a chipidea host and a dwc3 host

17:45 <bamse> z3ntu: are they independent ports? or just two connectors on the same usb interface?

17:46 <bamse> z3ntu: the cases of one controller multiple ports i've seen has all been host-only

18:04 <z3ntu> [@_oftc_bamse:matrix.org](https://matrix.to/#/@_oftc_bamse:matrix.org) I believe they function as separate ports at the same time, so you can connect something to the secondary one if you add a USB-A port to the logo pins and use the micro USB primary at the same time

18:04 <z3ntu> Schematics wise it's USB_HS1 pins on the SoC to one and USB_HS2 pins to the other

18:06 <z3ntu> [@konradybcio:matrix.org](https://matrix.to/#/@konradybcio:matrix.org) what does that mean in practical terms?

18:06 <z3ntu> Also host is what, phy, controller, or something else again?

18:08 <z3ntu> There's also some more details about this connector at https://github.com/dirkvl/FairPhone/tree/master/Electronics but also doesn't say much more

18:12 <konradybcio> host = controller

18:12 <konradybcio> phy is a fancy adc/dac

19:56 <lumag> z3ntu, I think it uses CI and dwc3 at the same time. At least on db8074 only some of the ports work.

19:57 <lumag> I didn't have time for that :-(

22:13 <minecrell> z3ntu: there is a register in TCSR to switch between dwc3 and chipidea, or something along those lines: https://github.com/msm8916-mainline/lk2nd/blob/1b7174a47f7a497c02f04e5951548cc685143dde/target/msm8974/init.c#L823, not sure what the bits do exactly

22:24 <minecrell> I’d expect this works only if you use dwc3 for main USB and chipidea for the second (or possibly the other way around)

22:25 <minecrell> So you’d need to make the dwc3 work first

22:39 <z3ntu> In any case, unfortunately this all sounds way more complicated than just enabling usb_2 or something :/

22:39 <z3ntu> I'll take a closer look tomorrow, but thanks for all your input!
