[PATCH] UHCI: various updates

This patch (as705) contains a small set of updates for uhci-hcd written
mostly by Dave Brownell:

  * Root hub suspend messages come out labeled as root hub messages;
    PCI messages should only come out when the pci device suspends.

  * Rename the reset() method to better match its init() role

  * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub
    suspend/resume errors.

  * When an URB fails, associate the message with the usb device not
    the host controller (it still hides endpoint and direction)

This updates the EHCI driver by adding an improved scheduler for the

full speed devices.

 - adds periodic_tt_usecs() and some helper functions, which does
   the same thing that "periodic_usecs" does, except on the other
   side of the TT, i.e.  it calculates the low/fullspeed bandwidth
   usage instead of highspeed.

 - adds a tt_available() function which is the new implementation
   of what tt_no_collision() does ... while tt_no_collision() ensures
   that each TT handles only 1 periodic transfer at a time (a very
   pessimistic approach) this version instead tracks bandwidth and
   allows each TT to handle as many transfers as will fit on each TT's
   downstream bus (closer to best-case).

[PATCH] USB: Remove 4088-byte limit on usbfs control URBs

This patch removes the artificial 4088-byte limit that usbfs
currently places on Control transfers. The USB spec does not
specify a strict limit on the size of an entire control transfer.
It does, however, state that the data stage "follows the same
protocol rules as bulk transfers." (USB 2, 8.5.3)

The level of support for large control transfers in real host
controllers varies, but it's important to support at least 4K
transfers. Windows enforces a maximum control transfer size
of 4K, so there exists some hardware that requires a full 4096
byte data stage. Without this patch, we fall short of that by
8 bytes on architectures with a 4K page size, and it becomes
impossible to support such hardware with a user-space driver.

Since any limit placed on control transfers by usbfs would be
arbitrary, this patch replaces the PAGE_SIZE limit with the same
arbitrary limit used by bulk transfers.

[PATCH] USB HID/HIDBP, INPUT DRIVERS: fix various usb/input/hid-input.c bugs that make Apple Mighty Mouse work poorly

Transposed lines of code in drivers/usb/input/hid-input.c causes the
capability bits for a new HID device to be set before quirks are applied
at configuration time.  When an HID event is then sent up to the input
layer, it may then be discarded as irrelevant because the wrong
capability bit is set.

Further, the quirks for the Apple Mighty Mouse are not quite right: the
horizontal scrolling needs its axis reversed, and the left and center
buttons are transposed.  Also, the mouse is labeled in the kernel with
its earlier name (I think) of Apple PowerMouse.

Steps to reproduce problem: Plug in an Apple Mighty Mouse.  Note that
horizontal scrolling doesn't work at all, and in fact doesn't generate
any input events on /dev/input/eventN.  Note also that pushing the
middle button performs the right button action, and vice versa.  Once
you have the horizontal scrolling working, note that it is backward WRT
both to vertical scrolling and to common sense.

This patch maybe should be broken up, as it does address two problems.
The transposed code in hidinput_configure_usage() probably creates bugs
beyond just the Mighty Mouse.  The rest of the patch renames POWERMOUSE
to MIGHTYMOUSE everywhere (which I *believe* is correct), fixes the
MIGHTYMOUSE quirk to swap the center and right mouse buttons, and adds a
new quirk HID_QUIRK_INVERT_HWHEEL also assigned to the MIGHTYMOUSE with
code in hidinput_hid_event() to implement it.

Some hubs claim not to support port-power switching, and right now the
hub driver believes them and does not enable power to their ports.
However it turns out that even though they don't actually switch power,
they do ignore all events on a port until told to turn on the power!
This problem has been reported by several users.

This revised patch (as672b) makes the hub driver always try to turn on
port power to all hubs, regardless of what the hub descriptor says.  It
also adds a comment explaining the need for this.

18 years ago[PATCH] Driver model: add ISA bus
Rene Herman [Tue, 6 Jun 2006 21:54:02 +0000 (23:54 +0200)]
[PATCH] Driver model: add ISA bus

During the recent "isa drivers using platform devices" discussion it was
pointed out that (ALSA) ISA drivers ran into the problem of not having
the option to fail driver load (device registration rather) upon not
finding their hardware due to a probe() error not being passed up
through the driver model. In the course of that, I suggested a seperate
ISA bus might be best; Russell King agreed and suggested this bus could
use the .match() method for the actual device discovery.

The attached does this. For this old non (generically) discoverable ISA
hardware only the driver itself can do discovery so as a difference with
the platform_bus, this isa_bus also distributes match() up to the driver.

As another difference: these devices only exist in the driver model due
to the driver creating them because it might want to drive them, meaning
that all device creation has been made internal as well.

The usage model this provides is nice, and has been acked from the ALSA
side by Takashi Iwai and Jaroslav Kysela. The ALSA driver module_init's
now (for oldisa-only drivers) become:

static int __init alsa_card_foo_init(void)
{
return isa_register_driver(&snd_foo_isa_driver, SNDRV_CARDS);
}

static void __exit alsa_card_foo_exit(void)
{
isa_unregister_driver(&snd_foo_isa_driver);
}

Quite like the other bus models therefore. This removes a lot of
duplicated init code from the ALSA ISA drivers.

The passed in isa_driver struct is the regular driver struct embedding a
struct device_driver, the normal probe/remove/shutdown/suspend/resume
callbacks, and as indicated that .match callback.

The "SNDRV_CARDS" you see being passed in is a "unsigned int ndev"
parameter, indicating how many devices to create and call our methods with.

The platform_driver callbacks are called with a platform_device param;
the isa_driver callbacks are being called with a "struct device *dev,
unsigned int id" pair directly -- with the device creation completely
internal to the bus it's much cleaner to not leak isa_dev's by passing
them in at all. The id is the only thing we ever want other then the
struct device * anyways, and it makes for nicer code in the callbacks as
well.

With this additional .match() callback ISA drivers have all options. If
ALSA would want to keep the old non-load behaviour, it could stick all
of the old .probe in .match, which would only keep them registered after
everything was found to be present and accounted for. If it wanted the
behaviour of always loading as it inadvertently did for a bit after the
changeover to platform devices, it could just not provide a .match() and
do everything in .probe() as before.

If it, as Takashi Iwai already suggested earlier as a way of following
the model from saner buses more closely, wants to load when a later bind
could conceivably succeed, it could use .match() for the prerequisites
(such as checking the user wants the card enabled and that port/irq/dma
values have been passed in) and .probe() for everything else. This is
the nicest model.

To the code...

This exports only two functions; isa_{,un}register_driver().

isa_register_driver() register's the struct device_driver, and then
loops over the passed in ndev creating devices and registering them.
This causes the bus match method to be called for them, which is:

int isa_bus_match(struct device *dev, struct device_driver *driver)
{
          struct isa_driver *isa_driver = to_isa_driver(driver);

          if (dev->platform_data == isa_driver) {
                  if (!isa_driver->match ||
                          isa_driver->match(dev, to_isa_dev(dev)->id))
                          return 1;
                  dev->platform_data = NULL;
          }
          return 0;
}

The first thing this does is check if this device is in fact one of this
driver's devices by seeing if the device's platform_data pointer is set
to this driver. Platform devices compare strings, but we don't need to
do that with everything being internal, so isa_register_driver() abuses
dev->platform_data as a isa_driver pointer which we can then check here.
I believe platform_data is available for this, but if rather not, moving
the isa_driver pointer to the private struct isa_dev is ofcourse fine as
well.

Then, if the the driver did not provide a .match, it matches. If it did,
the driver match() method is called to determine a match.

If it did _not_ match, dev->platform_data is reset to indicate this to
isa_register_driver which can then unregister the device again.

If during all this, there's any error, or no devices matched at all
everything is backed out again and the error, or -ENODEV, is returned.

isa_unregister_driver() just unregisters the matched devices and the
driver itself.

More global points/questions...

- I'm introducing include/linux/isa.h. It was available but is ofcourse
a somewhat generic name. Moving more isa stuff over to it in time is
ofcourse fine, so can I have it please? :)

- I'm using device_initcall() and added the isa.o (dependent on
CONFIG_ISA) after the base driver model things in the Makefile. Will
this do, or I really need to stick it in drivers/base/init.c, inside
#ifdef CONFIG_ISA? It's working fine.

Lastly -- I also looked, a bit, into integrating with PnP. "Old ISA"
could be another pnp_protocol, but this does not seem to be a good
match, largely due to the same reason platform_devices weren't -- the
devices do not have a life of their own outside the driver, meaning the
pnp_protocol {get,set}_resources callbacks would need to callback into
driver -- which again means you first need to _have_ that driver. Even
if there's clean way around that, you only end up inventing fake but
valid-form PnP IDs and generally catering to the PnP layer without any
practical advantages over this very simple isa_bus. The thing I also
suggested earlier about the user echoing values into /sys to set up the
hardware from userspace first is... well, cute, but a horrible idea from
a user standpoint.

Comments ofcourse appreciated. Hope it's okay. As said, the usage model
is nice at least.
