9ea1b7a4b6 [media] v4l2-ctrls: compare values only once
When setting a control the control's new value is compared to the current
value twice: once by new_to_cur(), once by cluster_changed(). Not a big
deal when dealing with simple values, but it can be a problem when dealing
with compound types or arrays. So fix this: cluster_changed() sets the
has_changed flag, which is used by new_to_cur() instead of having to do
another compare.

000e4f9a5b [media] v4l2-ctrls: rewrite copy routines to operate on union v4l2_ctrl_ptr
In order to implement array support and (for the future) configuration stores
we need to have more generic copy routines that all operate on the v4l2_ctrl_ptr
union. So instead of e.g. using ctrl->cur.string it uses ptr.p_char. This makes
e.g. cur_to_user generic so it can be used to copy any v4l2_ctrl_ptr value to
userspace, not just the (hardcoded) current value.

0176077a81 [media] v4l2-ctrls: create type_ops
Since compound controls can have non-standard types we need to be able to do
type-specific checks etc. In order to make that easy type operations are added.
There are four operations:

- equal: check if two values are equal
- init: initialize a value
- log: log the value
- validate: validate a new value

The v4l2_ctrl struct adds p_new and p_cur unions at the end of the struct.
This union provides a standard way of accessing control types through a pointer,
which greatly simplifies internal control processing.

d9a2547150 [media] v4l2-ctrls: add support for compound types
This patch implements initial support for compound types.

The changes are fairly obvious: basic support for is_ptr types, the
type_is_int function is replaced by a is_int bitfield, and
v4l2_query_ext_ctrl is added.

Note that this patch does not yet add support for N-dimensional
arrays, that comes later. So v4l2_query_ext_ctrl just sets elems to
1 and nr_of_dims and dims[] are all zero.

0ba2aeb6da [media] v4l2-ctrls: increase internal min/max/step/def to 64 bit
While VIDIOC_QUERYCTRL is limited to 32 bit min/max/step/def values
for controls, the upcoming VIDIOC_QUERY_EXT_CTRL isn't. So increase
the internal representation to 64 bits in preparation.

Because of these changes the msi3101 driver has been modified slightly
to fix a formatting issue (%d becomes %lld), vivi had to be modified
as well to cope with the new 64-bit min/max values and the PIXEL_RATE
control in a few sensor drivers required proper min/max/def values.

2fe152451d [media] gspca: provide a mechanism to select a specific transfer endpoint
Currently gspca selects the first ISOC input endpoint as the input
transfer endpoint, however some devices can provide streams on endpoints
different then the first one, so some subdrivers (e.g. gspca_kinect) may
want to select a specific endpoint to use as a transfer endpoint.

Add an xfer_ep field to struct gspca_dev, and change alt_xfer() so that
it accepts a parameter which represents a specific endpoint address to
look for.

If a subdriver wants to specify a value for gspca_dev->xfer_ep it can do
that in its sd_config() callback.

64ea37bbd8 [media] au0828: Only alt setting logic when needed
It seems that there's a bug at au0828 hardware/firmware
related to alternate setting: when the device is already at
alt 5, a further call causes the URBs to receive -ESHUTDOWN.

I found two different encarnations of this issue:

1) at qv4l2, it fails the second time we try to open the
video screen;
2) at xawtv, when audio underrun occurs, with is very
frequent, at least on my test machine.

The fix is simple: just check if alt=5 before calling
set_usb_interface().

3926d91a6b [media] dib7000p: Callibrate signal strength
Calibrate the signal strength to dB.

For this callibration, I used adapter 0 (antenna 1), connected
via a normal cable to a DTF-2111 generator.

The same cabling and RF generator connected to adapter 1
(antenna 2) has a difference of +3dBm (signal was stronger
there).

Yet, changing the RF for a difference of, let's say, 6dB
reflected on a 6dB difference at the measured signal, with
is good.

So, the signal strengh can indeed be used to measure the
antenna gain, if the antenna is repositioned. It is
not precise to measure the absolute dBm value, however.

041ad44968 [media] dib7000p: Add DVBv5 stats support
Adds DVBv5 stats support. For now, just mimic whatever dib8000
does, as they're very similar, with regards to statistics.

However, dib7000p_get_time_us() likely require some
adjustments, as I didn't actually reviewed the formula
for it to work with DVB-T. Still, better than nothing,
as latter patches can improve it.

This patch also doesn't show the signal strength in dB
yet. The code is already there, but it requires to be
callibrated.

A latter patch will do the calibration.

It seems that this patch is also a bug fix: Before this
patch, the frontend were not tuning with some userspace
tools. I suspect that dib7000p firmware or hardware
internally expects that the statistics to be collected,
in order for it to work. With this patch, the DVB core
will always retrive statistics, even if userspace doesn't
request. So, it makes the device work on all tested apps.

b9bc7d59b7 [media] dib8000: rename dib8000_attach to dib8000_init
Well, what we call as "foo_attach" is the method that should
be called by the dvb_attach() macro.

It should be noticed that the name "dvb_attach" is really a
bad name and don't express what it does.

dvb_attach() basically does three things, if the frontend is
compiled as a module:
- It lookups for the module that it is known to have the
  given symbol name and requests such module;
- It increments the module usage (anonymously - so lsmod
  doesn't print who loaded the module);
- after loading the module, it runs the function associated
  with the dynamic symbol.

When compiled as builtin, it just calls the function given to it.

As dvb_attach() increments refcount, it can't be (easily)
called more than once for the same module, or the kernel
will deny to remove the module, because refcount will never
be zeroed.

In other words, the function name given to dvb_attach()
should be one single symbol that will always be called
before any other function on that module to be used.

For almost all DVB frontends, there's just one function,
but, on dib8000, there are several exported symbols.

We need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that
will be the first one to be called, whatever initialization
is needed.

So, let's rename this function, in order to prepare for
a next patch that will add a new attach() function that
will be the only one exported by this module.

For almost all DVB frontends, there's just one function.

However, the dib7000p initialization can require up to 3
functions to be called:
	- dib7000p_get_i2c_master;
	- dib7000p_i2c_enumeration;
	- dib7000p_init (before this patch dib7000_attach).

(plus a bunch of other functions that the bridge driver will
need to call).

As we need to get rid of all those direct calls, because they
cause compilation breakages when bridge is builtin and
frontend is module, we'll need to add a new function that

allocated those buffers was never upstreamed since by the time the drivers were
added to the kernel the TI cmem module could be used in combination with the
USERPTR mode to reserve and pass physically contiguous memory pointers around.

These days of course CMA is used instead of cmem.

This patch removes these module options altogether since they no longer do what
they originally were designed for. They should never have been part of the
upstreamed code in the first place, so they've been pointless ever since
2.6.32 when this driver first appeared in the mainline kernel.

e5c4ecdc55 USB driver patches for 3.16-rc1
Here is the big USB driver pull request for 3.16-rc1.
 
 Nothing huge here, but lots of little things in the USB core, and in
 lots of drivers.  Hopefully the USB power management will be work better
 now that it has been reworked to do per-port power control dynamically.
 There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
 is finally gone now that everything has been converted over to the
 dynamic debug inteface, the last hold-out drivers were cleaned up and
 the config option removed.  There were also other minor things all
 through the drivers/usb/ tree, the shortlog shows this pretty well.
 
 All have been in linux-next, including the very last patch, which came
 from linux-next to fix a build issue on some platforms.

It wasn't even being used for anything, so remove the test for the
config option (as the config option isn't present anymore), and remove
the unused module parameter "debug" so as to not confuse anyone.

f7a27ff1fb [media] xc5000: delay tuner sleep to 5 seconds
Some drivers, like au0828 are very sensitive to tuner sleep and may
break if the sleep happens too fast. Also, by keeping the tuner alive
for a while could speedup tuning process during channel scan. So,
change the logic to delay the actual sleep to 5 seconds after its
command.
