Revert "usbcore: set lpm_capable field for LPM capable root hubs"

2014-02-22T21:34:56+00:00

commit 140e3026a57ab7d830dab2f2c57796c222db0ea9 upstream.

Commit 9df89d85b407690afa46ddfbccc80bec6869971d "usbcore: set
lpm_capable field for LPM capable root hubs" was created under the
assumption that all USB host controllers should have USB 3.0 Link PM
enabled for all devices under the hosts.

Unfortunately, that's not the case.  The xHCI driver relies on knowledge
of the host hardware scheduler to calculate the LPM U1/U2 timeout
values, and it only sets lpm_capable to one for Intel host controllers
(that have the XHCI_LPM_SUPPORT quirk set).

When LPM is enabled for some Fresco Logic hosts, it causes failures with
a AgeStar 3UBT USB 3.0 hard drive dock:

Revert "usb: xhci: Link TRB must not occur within a USB payload burst"

2014-02-22T21:34:56+00:00

commit 3d4b81eda2211f32886e2978daf6f39885042fc4 upstream.

This reverts commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e.  It's a
hack that caused regressions in the usb-storage and userspace USB
drivers that use usbfs and libusb.  Commit 70cabb7d992f "xhci 1.0: Limit
arbitrarily-aligned scatter gather." should fix the issues seen with the
ax88179_178a driver on xHCI 1.0 hosts, without causing regressions.

xhci 1.0: Limit arbitrarily-aligned scatter gather.

2014-02-22T21:34:55+00:00

commit 247bf557273dd775505fb9240d2d152f4f20d304 upstream.

xHCI 1.0 hosts have a set of requirements on how to align transfer
buffers on the endpoint rings called "TD fragment" rules.  When the
ax88179_178a driver added support for scatter gather in 3.12, with
commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a:
enable tso if usb host supports sg dma", it broke the device under xHCI
1.0 hosts.  Under certain network loads, the device would see an
unexpected short packet from the host, which would cause the device to
stop sending ethernet packets, even through USB packets would still be
sent.

Commit 35773dac5f86 "usb: xhci: Link TRB must not occur within a USB
payload burst" attempted to fix this.  It was a quick hack to partially
implement the TD fragment rules.  However, it caused regressions in the
usb-storage layer and userspace USB drivers using libusb.  The patches
to attempt to fix this are too far reaching into the USB core, and we
really need to implement the TD fragment rules correctly in the xHCI
driver, instead of continuing to wallpaper over the issues.

Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0
hosts.  Only the ax88179_178a driver checks the no_sg_constraint flag,
so don't set it for 1.0 hosts.  This should not impact usb-storage or
usbfs behavior, since they pass down max packet sized aligned sg-list
entries (512 for USB 2.0 and 1024 for USB 3.0).

usb-storage: enable multi-LUN scanning when needed

2014-02-22T21:34:55+00:00

commit 823d12c95c666fa7ab7dad208d735f6bc6afabdc upstream.

People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN.  This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.

Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN.  When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.

The patch also updates the Kconfig help text for usb-storage,
explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

usb-storage: restrict bcdDevice range for Super Top in Cypress ATACB

2014-02-22T21:34:54+00:00

commit a9c143c82608bee2a36410caa56d82cd86bdc7fa upstream.

The Cypress ATACB unusual-devs entry for the Super Top SATA bridge
causes problems.  Although it was originally reported only for
bcdDevice = 0x160, its range was much larger.  This resulted in a bug
report for bcdDevice 0x220, so the range was capped at 0x219.  Now
Milan reports errors with bcdDevice 0x150.

Therefore this patch restricts the range to just 0x160.
