f7acc4bb86 [media] em28xx: Fix DVB-C maxsize for em2884
The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.

Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.

For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.

cf845297d5 [media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHz
Currently, the driver assumes that all QAM carriers are spaced with
8MHz. This is wrong, and may decrease QoS on Countries like Brazil,
that have DVB-C carriers with 6MHz-spaced.

Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to
associate the symbol rate with the bandwidth needed for it.

For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.15 = 5217391 Bauds
For  ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.13 = 5309735 Bauds.

As this tuner is currently used only for DRX-K, and it is currently
hard-coded to annex A, I've opted to use the roll-off factor of 0.15,
instead of 0.13.

If we ever support annex C, the better would be to add a DVB S2API
call to allow changing between Annex A and C, and add the 0.13 roll-off
factor to it.

This code is currently being used on other frontends, so I think we
should later add a core function with this code, to warrant that
it will be properly implemented everywhere.

added new bit offset defines,
more supported BE colour formats
and also support BGR565 swapped pixel formats

removed pixfmt helper functions and option flags
setting the configuration register directly in set_pixfmt

added reg_mask function

reg_mask is basically the same as clearing & setting registers,
but it is more convenient and faster (saves one rw cycle).

more than enough to get standard NTSC 640x480x2x30 = ~17.6 MB/s isoc
bandwidth.

d749fb663e [media] au8522: set signal field to 100% when signal present
The signal state field in G_TUNER is typically scaled from 0-100%.  Since we
don't know the signal level, we really would prefer the field to contain 100%
than 1/256, which in many utilities (such as v4l2-ctl) rounds to 0% even when
a signal is actually present.

This patch makes the behavior consistent with other drivers.

Make use of the signal state registers to properly populate the signal lock

This allows applications to know whether there is a signal present even in

44ecf1df94 [media] cx231xx: Fix power ramping issue
On platforms that have CONFIG_HZ set to 100, the power ramp time effectively
ends up being 10ms.  However, on those that have a higher CONFIG_HZ, the time
ends up *actually* being 5ms, which doesn't allow enough time for the hardware
to be fully powered up before attempting to address it via i2c.

Change the constant to 10ms, which is long enough for the hardware to power
up, and won't really be anymore time than it was previously on platforms
with CONFIG_HZ being 100.

Credit goes to Mauro Carvalho Chehab and Gerd Hoffmann who previously
investigated this issue.

Tested with the Hauppauge USBLive 2, with which the problem was readily
reproducible after setting CONFIG_HZ to 1000.

992299e84a [media] Fix regression introduced which broke the Hauppauge USBLive 2
The following patch addresses the regression introduced in the cx231xx
driver which stopped the Hauppauge USBLive2 from working.

Confirmed working by both myself and the user who reported the issue
on the KernelLabs blog (Robert DeLuca).

At some point during refactoring of the cx231xx driver, the USBLive 2 device
became broken.  This patch results in the device working again.

c0c5e71e46 [media] uvcvideo: Fix control mapping for devices with multiple chains
The search for matching extension units fails to take account of the
current chain.  In the case where you have two distinct video chains,
both containing an XU with the same GUID but different unit ids, you
will be unable to perform a mapping on the second chain because entity
on the first chain will always be found first

Fix this by only searching the current chain when performing a control
mapping.  This is analogous to the search used by uvc_find_control(),
and is the correct behaviour.

320ed23ebf [media] drxk: Fix a bug at some switches that broke DVB-T
The error propagation changeset c23bf4402 broke the DVB-T
code.

The legacy way for propagate errors was:

do {
	status = foo_func()
	if (status < 0)
		break;
} while (0);
return status;

However, on a few places, it was doing:
do {
	switch(foo) {
	case bar:
		status = foo_func()
		if (status < 0)
			break;
		break;
	}
	switch(foo2) {
	case bar:
		status = foo_func()
		if (status < 0)
			break;
		break;
	}
	...
} while (0);
return (status)

The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.

Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

The right fix is to change them to use the same logic, but,

243bf1a24d [media] cx88: properly maintain decoder config when using MPEG encoder
The cx88 driver would force core->input to always be zero when doing the
the request_acquire().  While it wasn't actually changing the input register
in the hardware, the driver makes decision based on the current input.  In
particular, it decides whether to do things like enabling the comb filter
when on a composite input but disabling it on s-video.  So for example, on
the HVR-1300, using the s-video input with the MPEG encoder would end up with
the video decoder core configured as though the input type were composite.

In short, the driver state did not match the hardware state.

This patch does two things:

1.  It forces the input to zero only if actually switching to DVB mode.  This
prevents the input from changing when the blackbird driver opens the device.

2.  Keep track of what the input was set to when switching to DVB, and reset
it back when done.  This eliminates a condition where for example the user
had the analog side of the board set to capture on the s-video input, then
he used DVB for a bit, then the analog input would unexpectedly be set to
the tuner input.
