patch "usb: xhci: do not perform Soft Retry for some xHCI hosts" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: xhci: do not perform Soft Retry for some xHCI hosts to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From a4a251f8c23518899d2078c320cf9ce2fa459c9f Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka <stf_xl(a)wp.pl> Date: Thu, 11 Mar 2021 13:53:50 +0200 Subject: usb: xhci: do not perform Soft Retry for some xHCI hosts On some systems rt2800usb and mt7601u devices are unable to operate since commit f8f80be501aa ("xhci: Use soft retry to recover faster from transaction errors") Seems that some xHCI controllers can not perform Soft Retry correctly, affecting those devices. To avoid the problem add xhci->quirks flag that restore pre soft retry xhci behaviour for affected xHCI controllers. Currently those are AMD_PROMONTORYA_4 and AMD_PROMONTORYA_2, since it was confirmed by the users: on those xHCI hosts issue happen and is gone after disabling Soft Retry.

[PATCH 4/4] xhci: Fix repeated xhci wake after suspend due to uncleared internal wake state

by Mathias Nyman

If port terminations are detected in suspend, but link never reaches U0 then xHCI may have an internal uncleared wake state that will cause an immediate wake after suspend. This wake state is normally cleared when driver clears the PORT_CSC bit, which is set after a device is enabled and in U0. Write 1 to clear PORT_CSC for ports that don't have anything connected when suspending. This makes sure any pending internal wake states in xHCI are cleared.

[PATCH 3/4] usb: xhci: Fix ASMedia ASM1042A and ASM3242 DMA addressing

by Mathias Nyman

From: Forest Crossman <cyrozap(a)gmail.com> I've confirmed that both the ASMedia ASM1042A and ASM3242 have the same problem as the ASM1142 and ASM2142/ASM3142, where they lose some of the upper bits of 64-bit DMA addresses. As with the other chips, this can cause problems on systems where the upper bits matter, and adding the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.
