Mauro Carvalho Chehab 0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

Jemma Denson cf4f811479 [media] b2c2: Reset no_base_addr on skystarS2 attach failure
If set, all the other drivers reset no_base_addr on failure to
attach - git commit for this being added to some of them seems to
be eccd15aad7

This driver has been floating around outside the mainline for so
long it hasn't had this fix, so add it in.

Whilst here tidy surrounding code to fix style issues.

Jemma Denson 5afc9a25be [media] Add support for TechniSat Skystar S2
This patch adds support for the Technisat Skystar S2 - this
has been tried before but the cx24120 driver was a bit out of shape
and it didn't got any further:

https://patchwork.linuxtv.org/patch/10575/

It is an old card, but currently being sold off for next to nothing,
so it's proving quite popular of late. Noticing it's quite similar
to the cx24116 and cx24117 I've rewritten the driver in a similar way.

There were a few registers and commands from those drivers
missing from this one I've tested out and found they do something so
they've been added in to speed up tuning and to make get_frontend
return something useful.

Mauro Carvalho Chehab 89a2c1d60a [media] use a function for DVB media controller register
This is really a simple function, but using it avoids to have

Also, the kABI becomes a little more clearer.

This shouldn't generate any overhead, and the type check
will happen when compiling with MC DVB enabled.

We need to initialize the media controller earlier, as the core
will call the smsdvb hotplug during register time. Ok, this is
an async operation, so, when the module is not loaded, the media
controller works.

However, if the module is already loaded, nothing will be
registered at the media controller, as it will load too late.

Adding support for the media controller for a pure DVB device
is simple: just create a struct media_device and add it to the
dvb adapter. After creating all DVB devices, we need to call
the DVB core, for it to create the media graph.

More work is needed for pure DVB tuners, but this is hidden
at the Siano driver, just like several others non-hybrid
devices. So, this is streight forward.

David Härdeman c5540fbb9d [media] rc-core: remove protocol arrays
The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

Paul Bolle 3c4b422adb [media] sms: Remove CONFIG_ prefix from Kconfig symbols
X-Patchwork-Delegate: mchehab@redhat.com
Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for
SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files.

Note that the current (common sense) dependency on SMS_USB_DRV and
SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not
violate its constraints. These constraint are that:
- it should only be built if SMS_USB_DRV is set;
- it can't be builtin if USB support is modular.

So drop the dependency on SMS_USB_DRV, as it is unneeded.

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the

Mauro Carvalho Chehab 6c84b21428 [media] sms: fix randconfig building error
As reported by Jim Davis <jim.epost@gmail.com>,
building with:
	CONFIG_USB=m
	CONFIG_SMS_USB_DRV=m
	CONFIG_SMS_SDIO_DRV=y
	CONFIG_SMS_SIANO_MDTV=y
	CONFIG_SMS_SIANO_DEBUGFS=y

causes a build error:

	drivers/built-in.o: In function `smsdvb_debugfs_register':
	/home/jim/linux/drivers/media/common/siano/smsdvb-debugfs.c:537:
	undefined reference to `usb_debug_root'
	make: *** [vmlinux] Error 1

That happens because the siano-mdtv is builtin, while USB is a
module. As it makes not much sense to have sms-usb compiled as 'm'
and sms-sdio compiled as 'y' (or vice-versa), only allow enabling
debugfs if both are either 'y' or 'm'.

Mauro Carvalho Chehab 48a8a03b58 [media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001
Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
92002 does.

The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421
driver. In order to avoid regressions, the override is enabled
only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.

Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.

practice, as it would require the siano's firmware to return
an special invalid answer to a message request, fixing it
is trivial. So, let's do it.

There are two ways to specify firmware for siano devices: a

The per-device type logic is currently made by a 11x9 string
table, sparsely filled. It is very hard to read the table at

("none" there is a way to tell NULL).
Instead of using such problematic table, convert it into an
easy to read table, where the unused values will be defaulted
to NULL.

Mauro Carvalho Chehab 773adad141 [media] siano: fix status report with old firmware and ISDB-T
This seems to be ever broken. That's the status report with
Firmware 2.1, before adding support for sms2270 is:
[22273.787218] smsdvb_onresponse: MSG_SMS_GET_STATISTICS_RES
[22273.792592] IsRfLocked = 1
[22273.792592] IsDemodLocked = 1
...
[22273.792598] TransmissionMode = -64
...
(all unshown fields are filled with zeros)
Of course, transmission mode being a negative number is wrong.
So, we need to take a deeper look on it.
With the debugfs patches applied, it is possible to see that, instead
of filling StatisticsType with 5, and FullSize with the size of the
payload (this is what happens with sms2270 and firmware 8.1),
those fields are also initialized with zero:
StatisticsType = 0	FullSize = 0
IsRfLocked = 1		IsDemodLocked = 1	IsExternalLNAOn = 0
SNR = 0 dB		RSSI = 0 dBm		InBandPwr = 0 dBm
CarrierOffset = 0	Bandwidth = 0		Frequency = 0 Hz
TransmissionMode = -64	ModemState = 0		GuardInterval = 0
SystemType = 0		PartialReception = 0	NumOfLayers = 0
SmsToHostTxErrors = 0
The data under "TransmissionMode" varies according with the signal,
and it is negative. It also matches the value for InBandPwr when
the tuner is on DVB-T (ok, signal doesn't lock, but the power level
should be about the same with the antena fixed, and measured at about
the same time).
So, there's a very high chance that, when StatisticsType is zero, the
signal strength is at the same position as Transmission Mode.
So, discard all other parameters, and provide only signal/rf lock and
signal strength if StatisticsType is 0, for ISDB-T.

David Härdeman c003ab1bed [media] rc-core: add separate defines for protocol bitmaps and numbers
The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.

Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.

Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.

Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).

The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).

This patch separate the different usages in preparation for
upcoming patches.

Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.

The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

The current code invokes the auto calibration of the tuner whenever the
init routine is called (whenever the DVB frontend opens the device).
However we should really only be invoking the calibration if we actually
did reset the device and reload the firmware.

Rework the routine to only do calibration if reset and firmware load was
performed.  Also because the called function is now a no-op if the
firmware is already loaded, the caller no longer needs to invoke
is_firmware_loaded().

Mauro Carvalho Chehab 8cfd9dccf2 [media] media: Remove VIDEO_MEDIA Kconfig option
In the past, it was possible to have either DVB or V4L2 core
as module and the other as builtin. Such config never make much
sense, and created several issues in order to make the Kconfig
dependency to work, as all drivers that depend on both (most
TV drivers) would need to be compiled as 'm'. Due to that,
the VIDEO_MEDIA config option were added.

Instead of such weird approach, let's just use the MEDIA_SUPPORT
=y or =m to select if the media subsystem core will be either
builtin or module, simplifying the building system logic.

Also, fix the tuners configuration, by enabling them only if
a tuner is required. So, if just webcam/grabbers support is
selected, no tuner option will be selected. Also, if only digital
TV is selected, no analog tuner support is selected.

That removes the need of using EXPERT customise options, when
analog TV is not selected.

Hans Verkuil 5126f2590b [media] v4l2-dev: add flag to have the core lock all file operations
This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.

The drivers that didn't need this flag were:

drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c

The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.

Eventually this flag should go and it should not be used in new drivers.

There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).

It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.

For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.

While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.

I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

Miroslav Slugen 8a538a8855 [media] xc4000: add support for signal strength measures
In xc4000 chipsets real signal and noise level is stored in register
0x0A and 0x0B,so we can use those registers to monitor signal strength.

I tested this patch on 2 different cards Leadtek DVR3200 and DTV2000H
Plus, both with same results, I used special antenna hubs (toner 4x, 6x,
8x and 12x) with mesured signal lost, both registers are in dB value,
first represent signal with limit value -113.5dB (should be -114dB) and
exactly match with test results. Second represents noise level also in
dB and there is no maximum value, but from tests we can drop everything
above 32dB which tuner realy can't use, signal was usable till 20dB
noise level.

In digital mode we can take signal strength but sadly noise level is not
relevant and real value is stored in demodulator for now just zl10353,
also digital mode is just for testing, because it needs changing other
parts of code which reads data only from demodulator.

In analog mode I was able to test only FM radio, signal level is not
important, it says something about cable and hub losts, but nothing
about real quality of reception, so even if we have signal level at
minimum 113dB we can still here radio, because of that it is displaied
only in debug mode, but for real signal level is used noise register
which is again very accurate, radio noise level was betwen 6-20dB for
good signal, 20-25dB for medium signal, and above 25dB signal is
unusable.

For now real benefit of this patch is only for FM radio mode.

Gianluca Gennari 98ab8550ae [media] xc3028: fix center frequency calculation for DTV78 firmware
This patch replaces the previous one proposed in the thread "xc3028:
force reload of DTV7 firmware in VHF band with Zarlink demodulator",
at the linux-media@vger.kernel.org ML.

The problem is that the firmware DTV78 works fine in UHF band (8 MHz
bandwidth) but is not working at all in VHF band (7 MHz bandwidth).
Reading the comments inside the code, I figured out that the real
problem could be connected to the formula used to calculate the center
frequency offset in VHF band.

In fact, removing this adjustment fixes the problem:

		if ((priv->cur_fw.type & DTV78) && freq < 470000000)
			offset -= 500000;

This is coherent to what was implemented for the DTV7 firmware by an
Australian user:

		if (priv->cur_fw.type & DTV7)
			offset += 500000;

In the end, now the center frequency is the same for all firmwares
(DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth.

The final code looks clean and simple, and there is no need for any
"magic" adjustment:

		if (priv->cur_fw.type & DTV6)
			offset = 1750000;
		else	/* DTV7 or DTV8 or DTV78 */
			offset = 2750000;

At the analog side, cleans the logic that sets the several

Mauro Carvalho Chehab 99ac541254 [media] mt2063: Fix analog/digital set params logic
The driver were using a hacky way of setting analog and digital
frequencies. Remove the hack and properly add the tuner logic for
each supported type of standard.

I was tempted to add more standards there, like SECAM and to fix
radio (as stepping seems broken), but I opted to keep it as-is,
as tests would be needed to add additional standards.
