The dwc2 driver has everything we need to run in ACPI mode except for the ACPI module device table boilerplate. With that added and identified as "BCM2848", an id in use by other OSs for this device, the dw2 controller on the BCM2711 will work. Signed-off-by:

suspend() does its poisoning conditionally, resume() does it unconditionally. On a device with combined interfaces this will balance, on a device with two interfaces the counter will go negative and resubmission will fail. Both actions need to be done conditionally.

The port seems to be in an unknown state so the hub_activate during resume fails the hub_port_status, then the hub will fail to work. The quirky hub needs the reset-resume quirk to function correctly. Acked-by:

Fix a general protection fault reported by syzbot due to a race between gadget_setup() and gadget_unbind() in raw_gadget. The gadget core is supposed to guarantee that there won't be any more callbacks to the gadget driver once the driver's unbind routine is called. That guarantee is enforced in usb_gadget_remove_driver as follows: usb_gadget_disconnect(udc->gadget); if (udc->gadget->irq) synchronize_irq(udc->gadget->irq); udc->driver->unbind(udc->gadget); usb_gadget_udc_stop(udc); usb_gadget_disconnect turns off the pullup resistor, telling the host that the gadget is no longer connected and preventing the transmission of any more USB packets. Any packets that have already been received are sure to processed by the UDC driver's interrupt handler by the time synchronize_irq returns. But this doesn't work with dummy_hcd, because dummy_hcd doesn't use interrupts; it uses a timer instead. It does have code to emulate the effect of synchronize_irq, but that code doesn't get invoked at the right time -- it currently runs in usb_gadget_udc_stop, after the unbind callback instead of before. Indeed, there's no way for usb_gadget_remove_driver to invoke this code before the unbind callback. To fix this, move the synchronize_irq() emulation code to dummy_pullup so that it runs before unbind. Also, add a comment explaining why it is necessary to have it there.

The START_TRANSFER command needs to be executed while in ON/U0 link state (with an exception during register initialization). Don't use dwc->link_state to check this since the driver only tracks the link state when the link state change interrupt is enabled. Check the link state from DSTS register instead. Note that often the host already brings the device out of low power before it sends/requests the next transfer. So, the user won't see any issue when the device starts transfer then. This issue is more noticeable in cases when the device delays starting transfer, which can happen during delayed control status after the host put the device in low power.

Upon driver unbind usb_free_all_descriptors() function frees all speed descriptor pointers without setting them to NULL. In case gadget speed changes (i.e from super speed plus to super speed) after driver unbind only upto super speed descriptor pointers get populated. Super speed plus desc still holds the stale (already freed) pointer. Fix this issue by setting all descriptor pointers to NULL after freeing them in usb_free_all_descriptors().

When a PD charger advertising Rp-3.0 is connected to a sink port, the sink port current limit would 3A, during SNK_DISCOVERY, till power negotiation starts. Once the negotiation starts the power limit needs to drop down to pSnkStby(500mA @ 5V) and to negotiated current limit once the explicit contract is in place. Not all charging loops can ramp up to 3A and drop down to 500mA within tSnkStdby which is 15ms. The port partner might hard reset if tSnkStdby is not met. To solve this problem, this patch introduces slow-charger-loop which when set makes the port request PD_P_SNK_STDBY_MW upon entering SNK_DISCOVERY(instead of 3A or the 1.5A during SNK_DISCOVERY) and the actual currrent limit after RX of PD_CTRL_PSRDY for PD link or during SNK_READY for non-pd link.

>From PD Spec: The Sink Shall transition to Sink Standby before a positive or negative voltage transition of VBUS. During Sink Standby the Sink Shall reduce its power draw to pSnkStdby. This allows the Source to manage the voltage transition as well as supply sufficient operating current to the Sink to maintain PD operation during the transition. The Sink Shall complete this transition to Sink Standby within tSnkStdby after evaluating the Accept Message from the Source. The transition when returning to Sink operation from Sink Standby Shall be completed within tSnkNewPower. The pSnkStdby requirement Shall only apply if the Sink power draw is higher than this level. The above requirement needs to be met to prevent hard resets from port partner.

This patch adds a shutdown callback to USB DWC core driver to ensure that it is properly shutdown in reboot/shutdown path. This is required where SMMU address translation is enabled like on SC7180 SoC and few others. If the hardware is still accessing memory after SMMU translation is disabled as part of SMMU shutdown callback in system reboot or shutdown path, then IOVAs(I/O virtual address) which it was using will go on the bus as the physical addresses which might result in unknown crashes (NoC/interconnect errors).

Patch adds flag EP_UNCONFIGURED to detect whether endpoint was unconfigured. This flag is set in cdnsp_reset_device after Reset Device command. Among others this command disables all non control endpoints. Flag is used in cdnsp_gadget_ep_disable to protect controller against invoking Configure Endpoint command on disabled endpoint. Lack of this protection in some cases caused that Configure Endpoint command completed with Context State Error code completion. Fixes: 3d829045 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver") Signed-off-by:
