On STM32MP1 without the STUSB1600 USB-C chip (i.e. with plain USB-OTG
micro-B plug with ID and VBUS detection), the USB OTG port only works
if a micro-B device (e.g. a USB stick) is plugged in first. Once this
is done, both micro-B device and host (e.g. a PC via a USB A-to-microB
cable) are correctly detected and recognized. If a USB host is plugged
in first (e.g. a PC), then the PC does not detect the STM32MP1 at all.
By running the core connect code in dwc2_hcd_init(), both device and
host are detected and the USB works as expected. However, it is not
clear whether this is the correct solution.

GSNPSID = 0x4f54330a
GHWCFG1 = 0x00000000

STM32MP1 core doesn't support ACG feature: GHWCFG4_ACG_SUPPORTED = 0.
So, in your patch for STM32MP1 at least these lines are no meaning:
+ /* Enable ACG feature in device mode,if supported */
+ dwc2_enable_acg(hsotg);
Looks like you just copied this chirp from dwc2_conn_id_status_change()
function.
dwc2_hsotg_core_init_disconnected() function is device mode function,
not sure that it's safe to call it for host mode in dwc2_hcd_init().
Thanks,
Minas

The comment says it enables the ACG only if it's supported.

Yes, that's correct, verbatim.

OK well, if I don't use this patch and I plug in a USB cable from the
host PC, then the STM32MP1 isn't detected by the host PC. Do you have
any idea what the correct fix would be then ?

Please provide without your patch:
1. debugfs: params and hw_params
2. debug log
3. regdump before and after connecting device to host where issue seen.

To enable debug prints from dwc2 use 'make menuconfig':
Symbol: USB_DWC2_DEBUG [=y]
Type : bool
Prompt: Enable Debugging Messages
Location:
-> Device Drivers
-> USB support (USB_SUPPORT [=y])
(2) -> DesignWare USB2 DRD Core Support (USB_DWC2 [=m])
Defined at drivers/usb/dwc2/Kconfig:66
Depends on: USB_SUPPORT [=y] && USB_DWC2 [=m]
To get log use 'dmesg' command.
Thanks,
Minas

1. Are you sure that you provided full debug log for dwc2? Actually
first debug prints of dwc2 should be:
[72891.088917] dwc2 dwc2.1.auto: mapped PA ef100000 to VA 00000000ca45f000
[72891.088924] dwc2 dwc2.1.auto: registering common handler for irq16
[72891.088963] dwc2 dwc2.1.auto: Core Release: 4.00a (snpsid=4f54400a)
[72891.088974] dwc2 dwc2.1.auto: Forcing mode to host
[72891.100285] dwc2 dwc2.1.auto: Forcing mode to device
[72891.112307] dwc2 dwc2.1.auto: Clearing force mode bits
[72891.215275] dwc2 dwc2.1.auto: NonPeriodic TXFIFO size: 1024
[72891.215278] dwc2 dwc2.1.auto: RXFIFO size: 2048
...
2. Does your driver built for 'dual role device' or 'device only'?
3. First observation from register dumps: core in SOFT disconnect state,
which can be reason of observed issue. Could you please update your
patch and add only core_connect function call:
+ dwc2_hsotg_core_connect(hsotg);
+
return 0;
error4:
Or instead of patch, if you have any utility in system which will allow
from command line clear soft disconnect bit from DCTL register? Offset
of DCTL register is 0x804. SoftDiscon bit number is 1. Clear this bit
and then plug cable.
Unfortunately, currently I'm working from home and can't remotely
connect/disconnect cable in lab to try to reproduce observed by you issue.
Thanks,
Minas

So what you really want from me is to boot the kernel with loglevel >= 7
, right ? See at the end.

Dual-role

Does not help.

Clearing that bit with devmem allows the host PC to detect some
high-speed device got connected, but that's it, it does not detect it as
a gadget and no communication really happens.

Maybe you should consider using something like this in the lab:

Thanks for advise. I'll buy and setup multiplexer later, because

I have the zero gadget compiled into the kernel, I would expect that
should work too, right ?

Looks like I found cause of issue. According to your logs GINTMSK set
host masks, at least USB Reset not unmasked which required for device mode.
Why it happen. During dwc2 driver probe first initialized device part
then host part. Because of your g_zero is builtin in Kernel it
immediately bound to dwc2, as result called main device initialization
dwc2_hsotg_core_init_disconnected() which at least set GINTMSK for
device mode. After gadget side initialization done, dwc2 go to host
initialization hcd_init() and reset GINTMSK to host masks. In this case
connecting cable to host will ignore USBReset and stacked. Your initial
patch including call to function dwc2_hsotg_core_init_disconnected(),
which allow to restore device mode masks and on cable connect start
working as device.
First to check my assumption, please build g_zero as module and modprobe
it after dwc2 modprobe will be done. If the tests will pass then will
think how resolve issue with builtin functions.
Thanks,
Minas

Using g_zero as a module seems to work too, so please proceed.

Any news on using g_zero as built-in ?

Yes, that works, thanks.
This should likely get a Stable: tag when submitting.
