preparing to a big refactor on musb code. We need
to be able to compile in all glue layers (or at
least all ARM-based ones) together and have a

While preparing for that, we move every glue

a struct musb_platform_ops, and make all
other functions static.

Later patches will come to allow for compiling
all glue layers together and have a working

This patch makes sure not to assign the_card if gaudio_open_snd_dev fails,

Also make sure all filp's in gaudio_open_snd_dev is assigned NULL upon error
and gaudio_close_snd_dev only cleanups when the filp's are non-NULL.

fcf173e451 usb: musb: add names for IRQs in structure resource
Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.

Such database, might not have resources at
the expected order by the current drivers.

While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.

Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.

Function twl4030_usb_remove can cause unbalanced regulator disables in

Fix this by checking the 'asleep' variable in twl4030_usb_remove since that

02303f7337 usb-wwan: implement TIOCGSERIAL and TIOCSSERIAL to avoid blocking close(2)
Some devices (ex ZTE 2726) simply don't respond at all when data is sent
to some of their USB interfaces.  The data gets stuck in the TTYs queue
and sits there until close(2), which them blocks because closing_wait
defaults to 30 seconds (even though the fd is O_NONBLOCK).  This is
rarely desired.  Implement the standard mechanism to adjust closing_wait
and let applications handle it how they want to.

b17ea167c5 usbmon: correct length for isochronous
Usually the usbmon returns the amount of data specified in
urb->transfer_buffer_length for output submissions and urb->actual_length
for input callbacks. However, for Isochronous input transfers, this is
not enough, since the returned data buffer may contain "holes".

One easy way to fix this is to use urb->transfer_buffer_length,
but this often transfers a whole lot of unused data, so we find
how much was actually used instead.

811406c2e6 arm: omap4: add USBHOST and related base addresses
Add base addresses for USBHOST, USBTLL, EHCI and OHCI to
the header file.

This will disappear when the drivers are converted to use
the hwmod database, however this patch is needed until then.

4792a15bf0 usb: ehci-omap: Add OMAP4 support
Update the ehci-omap glue layer to support the controller in the
OMAP4. Major differences from OMAP3 is that the OMAP4 has per-port
clocking, and supports ULPI output clocking mode. The old input
clocking mode is not supported.

Also, there are only 2 externally available ports as against 3
in the OMAP3. The third port is internally tied off and should
not be used.

The EHCI controller in OMAP4 supports a new interface mode - HSIC.
Add this to the list of modes supported on OMAP3.

a42ccdc14d usb: ehci-omap: add helpers for checking port mode
Introduce helper functions to test port mode. These checks are
performed in several places in the driver, and these helpers
improve readability.

c5dff5545c usb: ehci-omap: use clkdev aliases for functional clocks
Use the recently updated aliases to get functional clocks needed by
the driver. This allows the driver to acquire OMAP4-specific clocks
without having to use different clock names for OMAP3 and OMAP4.

5467e16d89 omap: clock: add clkdev aliases for EHCI clocks
Add clkdev aliases for the USBHOST and USBTLL clocks on OMAP3 and
OMAP4, so that the driver can refer to the clocks using a common alias.

This will disappear when the driver is converted to use the hwmod
database, but until then this patch is needed.

7f124f4b35 usb: ehci: introduce CONFIG_USB_EHCI_HCD_OMAP
Introduce the CONFIG_USB_EHCI_HCD_OMAP option to select
EHCI support on OMAP3 and later chips. This scales better
than having a long line of dependencies for each new OMAP
with EHCI support.

Make the TLL channel count a parameter instead of a hardcoded
value. This allows us to be flexible with future OMAP revisions
which could have a different number of channels.

Rename usbhost2_120m_fck to usbhost_hs_fck and usbhost1_48m_fck
to usbhost_fs_fck, to better reflect the clocks' functionalities.

In OMAP4, the frequencies for the corresponding clocks are not
necessarily the same as with OMAP3, however the functionalities
are.
