usb: fixes for v3.5-rc3
A few remaining fixes for our v3.5 cycle containing a fix
for a long standing bug which would cause musb to starve its
dma channels by never releasing them, a build fix on lpc32xx_udc,
another fix to Ido's endpoint descriptor series on fsl udc, a
fix to the order of arguments on twl6030-usb driver and a
fix to dwc3's dequeue method.
All patches have been pending on the list for quite a while.

This patch (as1560) reverts commit
afff07e61a5243e14ee3f0a272a0380cd744a8a3 (usb-storage: Add 090c:1000
to unusal-devs). It is no longer needed, because usb-storage now
tells the sd driver to try READ CAPACITY(10) before READ CAPACITY(16)
for every USB mass-storage device.

Several bug reports have been received recently for USB mass-storage
devices that don't handle READ CAPACITY(16) commands properly. They
report bogus sizes, in some cases becoming unusable as a result.
The bugs were triggered by commit
09b6b51b0b6c1b9bb61815baf205e4d74c89ff04 (SCSI & usb-storage: add
flags for VPD pages and REPORT LUNS), which caused usb-storage to stop
overriding the SCSI level reported by devices. By default, the sd
driver will try READ CAPACITY(16) first for any device whose level is
above SCSI_SPC_2.
It seems likely that any device large enough to require the use of
READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ
CAPACITY(10) commands properly. Indeed, I don't know of any devices
that don't handle READ CAPACITY(10) properly.
Therefore this patch (as1559) adds a new flag telling the sd driver
to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag
for every USB mass-storage device. If a device really is larger than
2 TB, sd will fall back to READ CAPACITY(16) just as it used to.
This fixes Bugzilla #43391.

TEAC's UD-H01 (and probably other devices) have a gap in the interface
number allocation of their descriptors:
Configuration Descriptor:
bLength 9
bDescriptorType 2
wTotalLength 220
bNumInterfaces 3
[...]
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
[...]
Interface Association:
bLength 8
bDescriptorType 11
bFirstInterface 2
bInterfaceCount 2
bFunctionClass 1 Audio
bFunctionSubClass 0
bFunctionProtocol 32
iFunction 4
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 2
bAlternateSetting 0
[...]
Once a configuration is selected, usb_set_configuration() walks the
known interfaces of a given configuration and calls find_iad() on
each of them to set the interface association pointer the interface
is included in.
The problem here is that the loop variable is taken for the interface
number in the comparison logic that gathers the association. Which is
fine as long as the descriptors are sane.
In the case above, however, the logic gets out of sync and the
interface association fields of all interfaces beyond the interface
number gap are wrong.
Fix this by passing the interface's bInterfaceNumber to find_iad()
instead.

If the platform_data is not set, pdata will be uninitialized value.
Since the driver has the following code, if the condition is true when
the pdata is uninitialized value, the driver may jump to the illegal
phy_init().
if (pdata && pdata->phy_init)
pdata->phy_init();
This patch also fixes the following warning:

Its observed with some PHY, the 60Mhz clock gets
cut too soon for OMAP EHCI, leaving OMAP-EHCI in a bad state.
So on starting port suspend, make sure the 60Mhz clock to EHCI
is kept alive using an internal clock, so that EHCi can cleanly
transition its hw state machine on a port suspend.
Its not proven if this is the issue hit on USB3333,
but the symptoms look very similar.

xhci: Bug fixes for 3.5
Hi Greg,
Here's five bug fixes for 3.5. They fix some memory leaks in the
bandwidth calculation code, fix a couple bugs in the USB3 Link PM
patchset, and make system suspend and resume work on platforms with the
AsMedia ASM1042 xHCI host controller.
Sarah Sharp

When system software decides to power down the xHC with the intent of
resuming operation at a later time, it will ask xHC to save the internal
state and restore it when resume to correctly recover from a power event.
Two bits are used to enable this operation: Save State and Restore State.
xHCI spec 4.23.2 says software should "Set the Controller Save/Restore
State flag in the USBCMD register and wait for the Save/Restore State
Status flag in the USBSTS register to transition to '0'". However, it does
not define how long software should wait for the SSS/RSS bit to transition
to 0.
Currently the timeout is set to 1ms. There is bug report
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002697)
indicates that the timeout is too short for ASMedia ASM1042 host controller
to save/restore the state successfully. Increase the timeout to 10ms helps to
resolve the issue.
This patch should be backported to stable kernels as old as 2.6.37, that
contain the commit 5535b1d5f8885695c6ded783c692e3c0d0eda8ca "USB: xHCI:

This patch fixes a few issues introduced in the recent fix
[f8a9e72d: USB: fix resource leak in xhci power loss path]
- The endpoints listed in bw table are just links and each entry is an
array member of dev->eps[]. But the commit above adds a kfree() call
to these instances, and thus it results in memory corruption.
- It clears only the first entry of rh_bw[], but there can be multiple
ports.
- It'd be safer to clear the list_head of ep as well, not only
removing from the list, as it's checked in
xhci_discover_or_reset_device().

xhci_free_tt_info() may access the invalid memory when it removes the
last entry but the list is not empty. Then tt_next reaches to the
list head but it still tries to check the tt_info of that entry.
This patch fixes the bug and cleans up the messy code by rewriting
with a simple list_for_each_entry_safe().

The usb-serial-generic driver uses different device IDs for its USB
matching and its serial matching. This can lead to problems: The
driver can end up getting bound to a USB interface without being
allowed to bind to the corresponding serial port.
This patch (as1557) fixes the problem by using the same device ID
table (the one that can be altered by the "vendor=" and "product="
module parameters) for both purposes. The unused table is removed.
Now the driver will bind only to the intended devices.

We need to make sure that the USB serial driver we find
matches the USB driver whose probe we are currently
executing. Otherwise we will end up with USB serial
devices bound to the correct serial driver but wrong
USB driver.
An example of such cross-probing, where the usbserial_generic
USB driver has found the sierra serial driver:

So we end up with a mismatch between the USB driver and the
USB serial driver. The reason for the above is simple: The
USB driver probe will succeed if *any* registered serial
driver matches, and will use that serial driver for all
serial driver functions.
This makes ref counting go wrong. We count the USB driver
as used, but not the USB serial driver. This may result
in Oops'es as demonstrated by Johan Hovold <jhovold@gmail.com>:

Fix by only evaluating serial drivers pointing back to the
USB driver we are currently probing. This still allows two
or more drivers to match the same device, running their
serial driver probes to sort out which one to use.

This patch (as1558) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers. Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.
After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state. Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.
The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep. Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.
A similar patch has already been applied as commit
151b61284776be2d6f02d48c23c3625678960b97 (USB: EHCI: fix crash during
suspend on ASUS computers). The patch supersedes that one and reverts
it. There are two differences:
The old patch added the flag at the USB level; this patch
adds it at the PCI level.
The old patch applied to all chipsets with the same vendor,
subsystem vendor, and product IDs; this patch makes an
exception for a known-good system (based on DMI information).

The __devinitconst section can't be referenced
from usb_serial_device structure. Thus removed it as
it done in other mos* device drivers.

The low level helper returns 1 on success. The ioctl should however return
0. As this is the only user of the helper return, make the helper return 0 or

Later firmwares for this device now have proper subclass and
protocol info so we can identify it nicely without needing to use
the blacklist. I'm not removing the old 0xff matching as there
may be devices in the field that still need that.
