Pavol Kurina 4809ecc299 [PATCH] USB gadgetfs: fixes an error on writing to endpoint file
this patch fixes an "Invalid argument" error returned by a write to an
endpoint-file after reopening it in the gadgetfs module in the kernel
2.6.12.

This was testet only with dummy_hcd module!

David Brownell 91e79c91fa [PATCH] USB: Gadget library: centralize gadget controller numbers
This patch centralizes the assignment of bcdDevice numbers for different
gadget controllers.  This won't improve the object code at all, but it
does save a lot of repetitive and error-prone source code ... and will
simplify the work of supporting a new controller driver, since most new
gadget drivers will no longer need patches (unless some hardware quirks
limit USB protocol messaging).

Added minor cleanups and identifer hooks for the UDC in the Freescale
iMX series processors.

Ian Campbell e828264ee7 [PATCH] USB: gadget/ether build fixes.
I also needed the following on 2.6.13-rc1 without CONFIG_USB_ETH_RNDIS,
symbol fs_status_desc isn't available in that case on PXA255.

This builds both with and without ETH_RNDIS, but I haven't actually
tested either.

Alan Stern f1c39fad7d [PATCH] USB dummy_hcd: Centralize link state computations
This patch adds to the dummy_hcd driver a new routine for keeping track of
all changes in the state of the emulated USB link.  The logic is now kept
in one spot instead of spread around, and it's easier to verify and
update the code.  The behavior of the port features has been corrected in
a few respects as well (for instance, if the POWER feature is clear then
none of the other features can be set).

Also added is support for the (relatively new) _connect() and
_disconnect() calls of the Gadget API.

Alan Stern d9b762510c [PATCH] USB dummy_hcd: Use separate pdevs for HC and UDC
This patch makes the dummy_hcd driver create separate platform devices for
the emulated host controller and emulated device controller.  This gives a
more accurate simulation and will permit testing of situations where only
one of the two devices is suspended.

This also changes the name of the host controller platform device to match
the name of the driver.  That way the normal platform bus probe mechanism
will handle binding the driver to the device.

	Replace USB_PORT_FEAT_xxx with USB_PORT_STAT_xxx.  This is

Alan Stern 5742b0c950 [PATCH] USB dummy_hcd: Partial OTG emulation
Partial OTG support for dummy_hcd, mostly as a framework for further work.
It emulates the new OTG flags in the host and peripheral frameworks, if
that option is configured.  But it's incomplete:

  - Resetting the peripheral needs to clear the OTG state bits;
    a second enumeration won't work correctly.

  - This stops modeling HNP right when roles should switch the first time.
    It should probably disconnect, then set the usb_bus.is_b_host and
    usb_gadget.is_a_peripheral flags; then it'd enumerate almost normally,
    except for the role reversal.  Roles could then switch a second time,
    back to "normal" (with those flags cleared).

  - SRP should be modeled as "resume from port-unpowered", which is
    a state that usbcore doesn't yet use.

HNP can be triggered by enabling the OTG whitelist and configuring a
gadget driver that's not in that list; or by configuring Gadget Zero
to identify itself as the HNP test device.

David Brownell 65111084c6 [PATCH] USB: more omap_udc updates (dma and omap1710)
More omap_udc updates:

  * OMAP 1710 updates
      - new UDC bit for clearing endpoint toggle, affecting CLEAR_HALT
      - new OTG bits affecting wakeup
  * Fix the bug Vladimir noted, that IN-DMA transfer code path kicks in
    for under 1024 bytes (not "up to 1024 bytes")
  * Handle transceiver setup more intelligently
      - use transceiver whenever one's available; this can be handy
        for GPIO based, loopback, or transceiverless configs
      - cleanup correctly after the "unrecognized HMC" case
  * DMA performance tweaks
      - allow burst/pack for memory access
      - use 16 bit DMA access most of the time on TIPB
  * Add workarounds for some DMA errata (not observed "in the wild"):
      - DMA CSAC/CDAC reads returning zero
      - RX/TX DMA config registers bit 12 always reads as zero (TI patch)
  * More "sparse" warnings removed, notably "changing" the SETUP packet
    to return data in USB byteorder (an API change, null effect on OMAP
    except for these warnings).

David Brownell 907cba35f7 [PATCH] USB: ethernet gadget updates (mostly cleanup)
Some cleanup for the the Ethernet part of the Ethernet/RNDIS gadget driver:

  - Remove remnants of ancient endpoint init logic; this is simpler, clearer

  - Save a smidgeon of space in the object file

  - Get rid of some #ifdeffery, mostly by using some newish inlines

  - Reset more driver state as part of USB reset

  - Remove a needless wrapper around an RNDIS call

  - Improve and comment the status interrupt handling:
      * RNDIS sometimes needs to queue these transfers (rarely in normal
        cases, but reproducibly while Windows was deadlocking its USB stack)
      * Mark requests as busy/not

  - Enable the SET_NETDEV_DEV() call; sysfs seems to behave sanely now

This is a net shrink of source code.

David Brownell 340600ab4c [PATCH] USB: rndis updates (mostly cleanup)
Some bugfixes and lots of cleanup (net code shrink):

  - On reset, force the RNDIS state machine its initial state

  - Hook up the RNDIS (outgoing) filters to the CDC mechanism

  - Lots of cleanup:
     * Eliminate duplicate copy of OID table;
     * Unify handlying of the OID "query" response data pointer;
     * Reduce code duplication for calculating query response lengths;
     * Remove some checks for "can't happen" errors;
     * Get rid of debugging #ifdefs by making the debug flag an integer level

Most of the patch, by volume, relates to those query response cleanups.
It incidentally shaves off a few hundred bytes of object code.

Various USB patches, mostly for portability:

  - Fifo mode 1 didn't work previously (oopsed), so now it's fixed and
    (why not) defines even more endpoints for composite devices.

  - OMAP 1710 doesn't have an internal transceiver.

  - Small PM update:  if the USB link is suspended, don't disconnect on
    entry to deep sleep.

  - Be more correct about handling zero length control reads.  OMAP
    seems to mis-handle that protocol peculiarity though; best avoided.

  - Platform device resources (for UDC and OTG controllers) now use

Christoph Lameter 3e1d1d28d9 [PATCH] Cleanup patch for process freezing
1. Establish a simple API for process freezing defined in linux/include/sched.h:

   frozen(process)		Check for frozen process
   freezing(process)		Check if a process is being frozen
   freeze(process)		Tell a process to freeze (go to refrigerator)
   thaw_process(process)	Restart process
   frozen_process(process)	Process is frozen now

2. Remove all references to PF_FREEZE and PF_FROZEN from all
   kernel sources except sched.h

3. Fix numerous locations where try_to_freeze is manually done by a driver

4. Remove the argument that is no longer necessary from two function calls.

5. Some whitespace cleanup

6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
   cleared before setting PF_FROZEN, recalc_sigpending does not check
   PF_FROZEN).

This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!
