191c5f1027 TTY: call tty_port_destroy in the rest of drivers
After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

To be sure, the TTY buffers (and later some stuff) are gone along with
the tty_port, we have to call tty_port_destroy at tear-down places.
This is mostly where the structure containing a tty_port is freed.
This patch does exactly that -- put tty_port_destroy at those places.

 While removing g_file_storage, we also had to fix a bunch
 of defconfigs which were still pointing to the old gadget.
 
 There's a big series getting us closer to being able to
 introduce our configfs interface. The series converts
 functions into loadable modules which will, eventually,
 be registered to the configfs interface.
 
 Other than that there's the usual typo fixes and miscelaneous
 cleanups all over the place.

The maximum_speed/max_speed specifies maximum speed supported by UDC.

b100a2f34d usb: gadget: dummy_hcd: remove global the_controller variable
The one thing that makes two UDCs+HCDs impossible is the global
the_controller variable. This patch changes this. After device
allocation we allocate the "the_controller" variable and pass it as
platform_data to the UDC and its companion.
We can have now multiple instances dummy hcd and therefore I change the
limit from one to two. I was able to test this with g_ncm adn g_zero:

10287baec7 usb: gadget: always update HS/SS descriptors and create a copy of them
HS and SS descriptors are staticaly created. They are updated during the
bind process with the endpoint address, string id or interface numbers.

After that, the descriptor chain is linked to struct usb_function which
is used by composite in order to serve the GET_DESCRIPTOR requests,
number of available configs and so on.

There is no need to assign the HS descriptor only if the UDC supports
HS speed because composite won't report those to the host if HS support
has not been reached. The same reasoning is valid for SS.

This patch makes sure each function updates HS/SS descriptors
unconditionally and uses the newly introduced helper function to create a
copy the descriptors for the speed which is supported by the UDC.

While at that, also rename f->descriptors to f->fs_descriptors in order
to make it more explicit what that means.

0f9df93938 usb: gadget: uvc: fix error path in uvc_function_bind()
The "video->minor = -1" assigment is done in V4L2 by
video_register_device() so it is removed here.
Now. uvc_function_bind() calls in error case uvc_function_unbind() for
cleanup. The problem is that uvc_function_unbind() frees the uvc struct
and uvc_bind_config() does as well in error case of usb_add_function().
Removing kfree() in usb_add_function() would make the patch smaller but
it would look odd because the new allocated memory is not cleaned up.
However it is not guaranteed that if we call usb_add_function() we also
get to the bind function.
Therefore the patch extracts the conditional cleanup from
uvc_function_unbind() applies to uvc_function_bind().
uvc_function_unbind() now contains only the complete cleanup which is
required once everything has been registrated.

HS descriptors are assigned. If we plug it to an 1.1 host it won't work

3e9a6321f9 This is the first set of omap cleanup patches for v3.8 merge
window to remove most of the remaining plat includes to get us
 closer to ARM common zImage support.
 
 To avoid a huge amount of trivial merge conflicts with includes,
 this branch is based on several small topic branches coordinated
 with the driver subsystem maintainers. These branches are based on
 v3.7-rc1 and can also be merged into the related driver subsystem
 branches as needed:
 
 omap-for-v3.8/cleanup-headers-prepare   few trivial driver changes
 omap-for-v3.8/cleanup-headers-dma       move of the DMA header
 omap-for-v3.8/cleanup-headers-gpmc      GPMC and MTD changes

 omap-for-v3.8/cleanup-headers-dss       DSS related changes
 omap-for-v3.8/cleanup-headers-asoc      ASoC related changes
 
 Note that for the dma-omap.h, it was decided that it should be
 is completed. For the related discussion, please see:

 After these patches we still have a few plat headers remaining

6b7ced68f3 usb: fixes for v3.7-rc2
Here's the first set of fixes for v3.7-rc cycle.
 
 DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
 standing bug which would keep endpoint with BUSY flag set forever if we cancel
 a transfer which has already been started by the controller. The second fix
 will just switch PHYs back off when DWC3 driver is removed.
 
 MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
 removing a device. For some reason that particular device can fall into a
 situation where you have both Disconnect and Endpoint IRQs happen
 simultaneously (have both bits set in IRQ_STATUS register) and, because
 Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
 transfer data over a disconnected device, thus generating a kernel oops.
 
 Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
 the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
 in order to properly clear a single Interrupt event without clearing (and
 masking) other events we didn't handle yet.

The STOTG04 is an replacement for ISP1301.

Most of the registers on STOTG04 are the same as on ISP1301, but the
register ISP1301_I2C_OTG_CONTROL_2 (address 0x10) doesn't exist on the
ST part.

This is a work around for this by using the interrupt source register that
should behave the same on both parts and has the needed information.
