Pete Zaitcev d2fb1bb32b USB: sisusbvga: drop usb_buffer_alloc
This patch falls out of my work to fix usbmon so it uses virtual addresses.
It is not necessary, the "new" usbmon should work just fine with sisusbvga.
However, it seems ridiculous that anyone would use uncached memory to
transfer bulk data. Dropping the unnecessary use of usb_buffer_alloc
should be beneficial here, in case anyone ever uses the dongle on
anything beyond x86.

I had no success in raising the author of the driver by e-mail, so
the patch is not actually tested.

Sarah Sharp 6682bb39e1 USB: Fix SS endpoint companion descriptor parsing.
When there's a descriptor after the SuperSpeed endpoint companion
descriptor, the previous code would have skipped over twice the length it
was supposed to.  This code fixes crashes seen with UASP devices (which
have a UASP descriptor after the SS endpoint companion descriptor).

Sarah Sharp 624defa12f USB: xhci: Support interrupt transfers.
Interrupt transfers are submitted to the xHCI hardware using the same TRB
type as bulk transfers.  Re-use the bulk transfer enqueueing code to
enqueue interrupt transfers.

Interrupt transfers are a bit different than bulk transfers.  When the
interrupt endpoint is to be serviced, the xHC will consume (at most) one
TD.  A TD (comprised of sg list entries) can take several service
intervals to transmit.  The important thing for device drivers to note is
that if they use the scatter gather interface to submit interrupt
requests, they will not get data sent from two different scatter gather
lists in the same service interval.

For now, the xHCI driver will use the service interval from the endpoint's
descriptor (bInterval).  Drivers will need a hook to poll at a more
frequent interval.  Set urb->interval to the interval that the xHCI
hardware will use.

Sarah Sharp 2f697f6cbf USB: xhci: Set -EREMOTEIO when xHC gives bad transfer length.
The xHCI hardware reports the number of bytes untransferred for a given
transfer buffer.  If the hardware reports a bytes untransferred value
greater than the submitted buffer size, we want to play it safe and say no
data was transferred.  If the driver considers a short packet to be an
error, remember to set -EREMOTEIO.

Make sure that the amount of data the xHC says was transmitted is less
than or equal to the size of the requested transfer buffer.  Before, if
the host controller erroneously reported that the number of bytes
untransferred was bigger than the buffer in the URB, urb->actual_length
could be set to a very large size.

Make sure urb->actual_length <= urb->transfer_buffer_length.

On a successful transfer, urb->td is freed before the URB is ready to be
given back to the driver.  Don't touch urb->td after it's freed.  This bug
would have only shown up when xHCI debugging was turned on, and the freed
memory was quickly reused for something else.

Sarah Sharp 83fbcdcca0 USB: xhci: Handle babbling endpoints correctly.
The 0.95 xHCI spec says that non-control endpoints will be halted if a
babble is detected on a transfer.  The 0.96 xHCI spec says all types of
endpoints will be halted when a babble is detected.  Some hardware that
claims to be 0.95 compliant halts the control endpoint anyway.

When a babble is detected on a control endpoint, check the hardware's
output endpoint context to see if the endpoint is marked as halted.  If
the control endpoint is halted, a reset endpoint command must be issued
and the transfer ring dequeue pointer needs to be moved past the stopped
transfer.  Basically, we treat it as if the control endpoint had stalled.

Handle bulk babbling endpoints as if we got a completion event with a
stall completion code.

Sarah Sharp ac9d8fe7c6 USB: xhci: Add quirk for Fresco Logic xHCI hardware.
This Fresco Logic xHCI host controller chip revision puts bad data into
the output endpoint context after a Reset Endpoint command.  It needs a
Configure Endpoint command (instead of a Set TR Dequeue Pointer command)
after the reset endpoint command.

Set up the input context before issuing the Reset Endpoint command so we
don't copy bad data from the output endpoint context.  The HW also can't
handle two commands queued at once, so submit the TRB for the Configure
Endpoint command in the event handler for the Reset Endpoint command.

Devices that stall on control endpoints before a configuration is selected
will not work under this Fresco Logic xHCI host controller revision.

This patch is for prototype hardware that will be given to other companies
for evaluation purposes only, and should not reach consumer hands.  Fresco
Logic's next chip rev should have this bug fixed.

Sarah Sharp 82d1009f53 USB: xhci: Handle stalled control endpoints.
When a control endpoint stalls, the next control transfer will clear the
stall.  The USB core doesn't call down to the host controller driver's
endpoint_reset() method when control endpoints stall, so the xHCI driver
has to do all its stall handling for internal state in its interrupt handler.

When the host stalls on a control endpoint, it may stop on the data phase
or status phase of the control transfer.  Like other stalled endpoints,
the xHCI driver needs to queue a Reset Endpoint command and move the
hardware's control endpoint ring dequeue pointer past the failed control
transfer (with a Set TR Dequeue Pointer or a Configure Endpoint command).

Since the USB core doesn't call usb_hcd_reset_endpoint() for control
endpoints, we need to do this in interrupt context when we get notified of
the stalled transfer.  URBs may be queued to the hardware before these two
commands complete.  The endpoint queue will be restarted once both
commands complete.

Sarah Sharp 2d3f1fac7e USB: xhci: Support full speed devices.
Full speed devices have varying max packet sizes (8, 16, 32, or 64) for
endpoint 0.  The xHCI hardware needs to know the real max packet size
that the USB core discovers after it fetches the first 8 bytes of the
device descriptor.

In order to fix this without adding a new hook to host controller drivers,
the xHCI driver looks for an updated max packet size for control
endpoints.  If it finds an updated size, it issues an evaluate context
command and waits for that command to finish.  This should only happen in
the initialization and device descriptor fetching steps in the khubd
thread, so blocking should be fine.

Sarah Sharp 47aded8ade USB: xhci: Set correct max packet size for HS/FS control endpoints.
Set the max packet size for the default control endpoint on high speed
devices to be 64 bytes.  High speed devices always have a max packet size
of 64 bytes.  There's no use setting it to eight for the initial 8 byte
descriptor fetch and then issuing (and waiting for) an evaluate context
command to update it to 64 bytes for the subsequent control transfers.

The USB core guesses that the max packet size on a full speed control
endpoint is 64 bytes, and then updates it after the first 8-byte
descriptor fetch.  Change the initial setup for the xHCI internal
representation of the full speed device to have a 64 byte max packet size.

Sarah Sharp b0567b3f63 USB: xhci: Work around for chain bit in link TRBs.
Different sections of the xHCI 0.95 specification had opposing
requirements for the chain bit in a link transaction request buffer (TRB).
The chain bit is used to designate that adjacent TRBs are all part of the
same scatter gather list that should be sent to the device.  Link TRBs can
be in the middle, or at the beginning or end of these chained TRBs.

Sections 4.11.5.1 and 6.4.4.1 both stated the link TRB "shall have the
chain bit set to 1", meaning it is always chained to the next TRB.
However, section 4.6.9 on the stop endpoint command has specific cases for
what the hardware must do for a link TRB with the chain bit set to 0.  The
0.96 specification errata later cleared up this issue by fixing the
4.11.5.1 and 6.4.4.1 sections to state that a link TRB can have the chain
bit set to 1 or 0.

The problem is that the xHCI cancellation code depends on the chain bit of
the link TRB being cleared when it's at the end of a TD, and some 0.95
xHCI hardware simply stops processing the ring when it encounters a link
TRB with the chain bit cleared.

Allow users who are testing 0.95 xHCI prototypes to set a module parameter
(link_quirk) to turn on this link TRB work around.  Cancellation may not
work if the ring is stopped exactly on a link TRB with chain bit set, but
cancellation should be a relatively uncommon case.

Michael Abbott f266889517 drivers/hwmon/adm1021.c: support high precision ADM1023 remote sensor
The ADM1023 temperature sensor supports higher resolution for its external
sensor (sensitivity of 1/8 deg C).  This patch makes this higher
resolution available through the appropriate temperature sysfs nodes.

Curiously, this functionality was available in the 2.4 kernel driver (but
formatted in a less helpful manner).

Daniel Mack 2cd9645e2f lis3: add power management functions
This enabled power management functions for the SPI transport layer of the
lis3 devices.  The device's suspend mode is only entered in case no wakeup
threshold has been given.  In this case, the device is supposed to wake up
the system and must thus not be put to deep sleep.

Michael Riepe 0bf41d9f41 drivers/hwmon/coretemp.c: enable the Intel Atom
Enable the coretemp driver on an Intel Atom.

I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load).  Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.

Mike Frysinger 42e41c54d6 checkpatch: add some common Blackfin checks
Add checks for Blackfin-specific issues that seem to crop up from time to
time.  In particular, we have helper macros to break a 32bit address into
the hi/lo parts, and we want to make sure people use the csync/ssync
variant that includes fun anomaly workarounds.

the text after a C99 style comment the same way it does with block style
