I would prefer to fix the suspend/resume behavior reported here [1] instead of making tricky workarounds. But i don't have an idea how to achieve this.

From my understanding Samsung noticed this issue at first and introduced the no_clock_gating flag [1] and they referenced 0112b7ce68ea ("usb: dwc2: Update dwc2_handle_usb_suspend_intr function.") as I did in this patch. Later some platforms like Rockchip and Agilex followed.

I wouldn't conclude that the chip can always serve as a wakeup source (e.g. power down the USB domain would also prevent this), but i agree creating a relation between wakeup source and clock gating is a bad idea. > The real question is whether BCM2848 platforms likewise cannot disable > the clock of the dwc2 controller or whether this is specific to the > BCM2835.

This id comes from the edk2-platforms ACPI tables and is currently used by both the rpi3 and rpi4, and AFAIK nothing else as the rpi5-dev work is currently only exposing XHCI. The ID is strictly the USB controller not the SoC. Its a bit confusingly named, but something we inherited from the much older windows/edk2 port, where it appears that the peripheral HID's were just picked in numerical order.

You could say that, but there was some due diligence a couple years ago to track down the owner of the pnp id/information at broadcom, and it didn't yield anything helpful. Whether they are legitimate seems to be lost in time.
