dma: pl330: rip out broken, redundant ID probing
The PL330 driver probes the peripheral and primecell IDs of the device to
make sure that it is indeed an AMBA PL330. However, it does this by
making byte accesses to a device mapping of the word-aligned ID
registers, which is either UNPREDICTABLE or generates an alignment fault
(depending on the presence of the virtualisation extensions).
Rather than fix this code, we can actually rip most of it out and let
the AMBA bus driver correctly do the probing for us.

[media] V4L2: support asynchronous subdevice registration
Currently bridge device drivers register devices for all subdevices
synchronously, typically, during their probing. E.g. if an I2C CMOS sensor
is attached to a video bridge device, the bridge driver will create an I2C
device and wait for the respective I2C driver to probe. This makes linking
of devices straight forward, but this approach cannot be used with
intrinsically asynchronous and unordered device registration systems like
the Flattened Device Tree. To support such systems this patch adds an
asynchronous subdevice registration framework to V4L2. To use it respective
(e.g. I2C) subdevice drivers must register themselves with the framework.
A bridge driver on the other hand must register notification callbacks,

Typical video devices like camera sensors require an external clock source.
Many such devices cannot even access their hardware registers without a

This should be performed, using the generic clock framework. Unfortunately
so far only very few systems have been ported to that framework. This patch

Normally the clock supplier module is prevented to be unloaded by

For cases when the clock supplier module deinitializes despite the
consumers of its clocks holding a reference on the module, e.g. when
the driver is unbound through "unbind" sysfs attribute, there are
empty clock ops added. These ops are assigned temporarily to struct
clk and used until all consumers release the clock, to avoid invoking

usb/gadget: f_mass_storage: split fsg_common initialization into a number of functions
When configfs is in place, the things related to intialization
of struct fsg_common will be split over a number of places.
This patch adds several functions which together cover the former
intialization routine fsg_common_init.
When configfs is in place, the luns will not be represented in sysfs,
so there will be no struct device associated with a lun.
To prepare for this some debug macros need to be adjusted. Two new
fields are added to struct fsg_lun: name and name_pfx.
The "name" is for storing a string which is presented to the user
instead of the dev_name. The "name_pfx", if non-NULL, is prepended
to the "name" at printing time.
The name_pfx is for a future lun.0, which will be a default group in
mass_storage.<name>. By design at USB function configfs group's creation
time its name is not known (but instead set a bit later in
drivers/usb/gadget/configfs.c:function_make) and it is this name that
serves the purpose of the said name prefix. So instead of copying
a yet-unknown string a pointer to it is stored in struct fsg_lun.

usb/gadget: f_mass_storage: add a level of indirection for luns storage
This is needed to prepare for configfs integration.
So far the luns have been allocated during gadget's initialization, based
on the nluns module parameter's value; the exact number is known when the
gadget is initialized and that number of luns is allocated in one go; they
all will be used.
When configfs is in place, the luns will be created one-by-one by the user.
Once the user is satisfied with the number of luns, they activate the
gadget. The number of luns must be <= FSG_MAX_LUN (currently 8), but other
than that it is not known up front and the user need not use contiguous
numbering (apart from the default lun #0). On the other hand, the function
code uses lun numbers to identify them and the number needs to be used
as an index into an array.
Given the above, an array needs to be allocated, but it might happen that
7 out of its 8 elements will not be used. On my machine
sizeof(struct fsg_lun) == 462, so > 3k of memory is allocated but not used
in the worst case.
By adding another level of indirection (allocating an array of pointers
to struct fsg_lun and then allocating individual luns instead of an array
of struct fsg_luns) at most 7 pointers are wasted, which is much less.
This patch also changes some for/while loops to cope with the fact
that in the luns array some entries are potentially empty.

Converting to configfs requires making the f_mass_storage.c a module.

This patch makes storage_common.c a separately compiled file, which is
built as a utility module named u_ms.ko. After all mass storage users are

by merging it with the mass storage function's module.
USB descriptors are exported so that they can be accessed from
f_mass_storage.
FSG_VENDOR_ID and FSG_PRODUCT_ID are moved to their only user.
Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c.
The fsg_num_buffers static is moved to FSG_MODULE_PARAMETER users, so

If usb_add_function() fails then the currently processed function
is already not in the list in struct config_usb_cfg, and neither is it
in the list in struct usb_configuration. At the err_purge_funcs label the
purge_config_funcs() is called, which iterates over all configurations,
and in each configuration it iterates over all _successfully_ added
functions, and moves them back from the list in struct usb_configuration
to the list in struct config_usb_cfg. BUT the function which has just
failed adding and caused the unwind process is not taken care of and
is effectively lost.
This patch modifies the configfs_composite_bind() function so that if
the usb_add_function() fails, then the currently processed function
is returned to the list in struct config_usb_cfg.
It would be tempting to delay the list_del() in question after
usb_add_function() invocation, but a struct list_head (&f->list) cannot be
stored in more than one list at the same time, so the list_del() must
be called before usb_add_function(). Hence, the solution is to list_add()
after usb_add_function() in case of error.
