Hans Verkuil 1f4522400e [media] [for,v4.5] media.h: increase the spacing between function ranges
Each function range is quite narrow and especially for connectors this
will pose a problem. Increase the function ranges while we still can and
move the connector range to the end so that range is practically limitless.

Mauro Carvalho Chehab c43875f661 [media] tvp5150: replace MEDIA_ENT_F_CONN_TEST by a control
MEDIA_ENT_F_CONN_TEST is not really a connector, it is actually
a signal generator. Also, as other drivers use the
V4L2_CID_TEST_PATTERN control for signal generators, let's change
the driver accordingly.

Tested with Terratec Grabster AV350.

Mauro Carvalho Chehab 153d41a1d0 [media] v4l2-mc: remove the unused sensor var
This fixes this warning:

	v4l2-mc.c: In function 'v4l2_mc_create_media_graph':
	v4l2-mc.c:60:69: warning: variable 'sensor' set but not used [-Wunused-but-set-variable]

We could solve it the other way: don't do the second loop for
webcams. However, that would fail if a chip would have two sensors
plugged. This is not the current case, but it doesn't hurt to be
future-safe here, specially since this code runs only once during
device probe. So, performance is not an issue here.

Mauro Carvalho Chehab bb07bd6b68 [media] allow overriding the driver name
On USB drivers, the dev struct is usually filled with the USB
device. That would mean that the name of the driver specified
by media_device.dev.driver.name would be "usb", instead of the
name of the actual driver that created the media entity.

Add an optional field at the internal struct to allow drivers
to override the driver name.

Mauro Carvalho Chehab c73bbaa4ec [media] rc-core: don't lock device at rc_register_device()
The mutex lock at rc_register_device() was added by commit 08aeb7c9a4
("[media] rc: add locking to fix register/show race").

It is meant to avoid race issues when trying to open a sysfs file while
the RC register didn't complete.

In this specific case, some error happened during device init,
causing IR to be disabled.

Let's fix it by adding a var that will tell when the device is
initialized. Any calls before that will return a -EINVAL.

That should prevent the race issues.

Javier Martinez Canillas f7b4b54e63 [media] tvp5150: add HW input connectors support
The tvp5150 decoder has different input connectors. The actual list of
HW inputs depends on the device version but all have at least these 3:

1) Composite0
2) Composite1
3) S-Video

and some variants have a 4th possible input connector:

4) Signal generator

The driver currently uses the .s_routing callback to switch the input
connector but since these are separate HW blocks, it's better to use
media entities to represent the input connectors and their source pads
linked with the decoder's sink pad.

This allows user-space to use the MEDIA_IOC_SETUP_LINK ioctl to choose
the input connector. For example using the media-ctl user-space tool:

$ media-ctl -r -l '"Composite0":0->"tvp5150 1-005c":0[1]'

Mauro Carvalho Chehab 7b606ffd65 [media] au0828: move V4L2-specific code to au0828-core.c
Instead of having lots of #ifdefs inside au0828-core due to
V4L2, move the dependencies to au0828-video.c. That allows
removing all those ifdefs, as au0828-video is only compiled if
CONFIG_VIDEO_AU0828_V4L2.

This fixes the following warnings reported by Kbuild test
with a random config with au0828 enabled, but V4L2 is disabled.

All warnings (new ones prefixed by >>):

   drivers/media/usb/au0828/au0828-core.c: In function 'au0828_usb_probe':
>> drivers/media/usb/au0828/au0828-core.c:463:1: warning: label 'done' defined but not used [-Wunused-label]

Mauro Carvalho Chehab 82e92f4cad [media] au0828: only create V4L2 graph if V4L2 is registered
It doesn't make sense to try to create the analog TV graph,
if the device fails to register at V4L2, or if it doesn't have
V4L2 support.

Thanks to Shuah for pointing this issue.

Mauro Carvalho Chehab 8bf77f9e70 [media] saa7134: Get rid of struct saa7134_input.tv field
The saa7134_input.tv field was used to indicate if an input had
a RF signal for TV input. This is not needed anymore, as the input
type can be checked directly by the driver.

Also, due to a past bug when setting the TV standard at the
demod, all inputs should have this field set, with is wrong.

This reduces the size of the saa7134_boards by about 8KB,
on i386 (and probably twice on 64 bits), with is a nice
colateral effect:

Mauro Carvalho Chehab 8fc3486783 [media] saa7134: use input types, instead of hardcoding strings
Currently, the saa7134 driver is hardcoding input names on each
board entry. More modern drivers define, instead, an enum for each
input type.

While the current logic works, it adds extra complexity at the driver,
as it needs to discover the type of the input using some euristics.

Instead, let's standardize the input types and use a type, instead of
a name on all places.

That will allow further patches to properly report the input type
via VIDIOC_G_INPUT and to remove an extra field from the struct to
identify if the input is for TV.

Please notice that several boards define an input for receiving composite
signals via a S-Video connector. The name of such input was inconsistent,
so this patch cleans it and make it to be properly reported the
same way for all boards.

by getting rid of em28xx-specific code, relying only at the

Linus Torvalds c17dfb019d ARM: SoC fixes for v4.5-rc
The first real batch of fixes for this release cycle, so there are a few more
 than usual.
 
 Most of these are fixes and tweaks to board support (DT bugfixes, etc). I've
 also picked up a couple of small cleanups that seemed innocent enough that
 there was little reason to wait (const/__initconst and Kconfig deps).
 
 Quite a bit of the changes on OMAP were due to fixes to no longer write to
 rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also
 other fixes.
 
 Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC fixes
 on OMAP5, and Nomadik had changes to MMC parameters in DT.
 
 All in all, mostly the usual mix of various fixes.
