+Subject: usb: dwc3: core: Prevent phy suspend during init
+
+From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>
+
+commit 6d735722063a945de56472bdc6bfcb170fd43b86 upstream.
+
+GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY should be cleared
+during initialization. Suspend during initialization can result in
+undefined behavior due to clock synchronization failure, which often
+seen as core soft reset timeout.
+
+The programming guide recommended these bits to be cleared during
+initialization for DWC_usb3.0 version 1.94 and above (along with
+DWC_usb31 and DWC_usb32). The current check in the driver does not
+account if it's set by default setting from coreConsultant.
+
+This is especially the case for DRD when switching mode to ensure the
+phy clocks are available to change mode. Depending on the
+platforms/design, some may be affected more than others. This is noted
+in the DWC_usb3x programming guide under the above registers.
+
+Let's just disable them during driver load and mode switching. Restore
+them when the controller initialization completes.
+
+Note that some platforms workaround this issue by disabling phy suspend
+through "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when
+they should not need to.

+Subject: usb: Fix regression caused by invalid ep0 maxpacket in virtual SuperSpeed device
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit c78c3644b772e356ca452ae733a3c4de0fb11dc8 upstream.
+
+A virtual SuperSpeed device in the FreeBSD BVCP package
+(https://bhyve.npulse.net/) presents an invalid ep0 maxpacket size of 256.
+It stopped working with Linux following a recent commit because now we
+check these sizes more carefully than before.
+
+Fix this regression by using the bMaxpacketSize0 value in the device
+descriptor for SuperSpeed or faster devices, even if it is invalid. This
+is a very simple-minded change; we might want to check more carefully for
+values that actually make some sense (for instance, no smaller than 64).

+
+From: Peter Korsgaard <peter@korsgaard.com>
+
+commit ec6ce7075ef879b91a8710829016005dc8170f17 upstream.
+
+The OS descriptors logic had the high/low byte of w_value inverted, causing
+the extended properties to not be accessible for interface != 0.
+
+>From the Microsoft documentation:
+https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/microsoft-os-1-0-descriptors-specification
+
+OS_Desc_CompatID.doc (w_index = 0x4):
+
+- wValue:
+
+ High Byte = InterfaceNumber. InterfaceNumber is set to the number of the
+ interface or function that is associated with the descriptor, typically
+ 0x00. Because a device can have only one extended compat ID descriptor,
+ it should ignore InterfaceNumber, regardless of the value, and simply
+ return the descriptor.
+
+ Low Byte = 0. PageNumber is used to retrieve descriptors that are larger
+ than 64 KB. The header section is 16 bytes, so PageNumber is set to 0 for
+ this request.
+
+We currently do not support >64KB compat ID descriptors, so verify that the
+low byte is 0.
+
+OS_Desc_Ext_Prop.doc (w_index = 0x5):
+
+- wValue:
+
+ High byte = InterfaceNumber. The high byte of wValue is set to the number
+ of the interface or function that is associated with the descriptor.
+
+ Low byte = PageNumber. The low byte of wValue is used to retrieve
+ descriptors that are larger than 64 KB. The header section is 10 bytes, so
+ PageNumber is set to 0 for this request.
+
+We also don't support >64KB extended properties, so verify that the low byte
+is 0 and use the high byte for the interface number.

+Subject: usb: ohci: Prevent missed ohci interrupts
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+commit fe81f354841641c7f71163b84912b25c169ed8ec upstream.
+
+Testing ohci functionality with qemu's pci-ohci emulation often results
+in ohci interface stalls, resulting in hung task timeouts.
+
+The problem is caused by lost interrupts between the emulation and the
+Linux kernel code. Additional interrupts raised while the ohci interrupt
+handler in Linux is running and before the handler clears the interrupt
+status are not handled. The fix for a similar problem in ehci suggests
+that the problem is likely caused by edge-triggered MSI interrupts. See
+commit 0b60557230ad ("usb: ehci: Prevent missed ehci interrupts with
+edge-triggered MSI") for details.
+
+Ensure that the ohci interrupt code handles all pending interrupts before
+returning to solve the problem.

+Subject: usb: xhci-plat: Don't include xhci.h
+
+From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>
+
+commit 4a237d55446ff67655dc3eed2d4a41997536fc4c upstream.
+
+The xhci_plat.h should not need to include the entire xhci.h header.
+This can cause redefinition in dwc3 if it selectively includes some xHCI
+definitions. This is a prerequisite change for a fix to disable suspend
+during initialization for dwc3.
