Remove tuner_callback pointers from tuner driver configuration
and private state structures, replaced with a general-purpose
callback pointer within struct dvb_frontend.
A new parameter is added to the callback function, called
component. This allows us to use this callback pointer by
frontend components other than the tuner, if need be. So
far, this is only used by tuner drivers.

The Pinnacle PCTV HD Pro has an xc5000, which exposed a bug in the dib0700's
i2c implementation where it did not properly support a single i2c read request
(sending it as an i2c write request instead). Version 1.20 of the firmware
added support for a new i2c API which supported such requests.
This change defaults to fw 1.20 for all devices, but does not default to using
the new i2c API (since initial testing suggests problems interacting with the
mt2060). Maintainers can enable the use of the new i2c API by putting
the following into their frontend initialization:
struct dib0700_state *st = adap->dev->priv;
st->fw_use_new_i2c_api = 1;
Also note that the code expects i2c repeated start to be supported. If the
i2c slave does not support repeated start, i2c messsages should have the
I2C_M_NOSTART flag set.
Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing new
firmware fixing the issue as well as example i2c code utilizing the interface.

Auto-update controls are never marked is loaded to prevent uvc_get_ctrl from
loading the control value from the cache. When setting a composite (mapped to
several V4L2 controls) auto-update UVC control, the driver updates the control
cache value before processing each V4L2 control, overwriting the previously
set V4L2 control.
This fixes the problem by marking all controls as loaded in uvc_set_ctrl
regardless of their type and resetting the loaded flag in uvc_commit_ctrl for

instead of register_chrdev", the internal reference count is no longer
necessary in order to free the internal stk_webcam struct. This patch
removes the reference counter from the stk_webcam struct and frees the
struct via the video_device release callback. It also fixes an
associated bug in stk_camera_probe which could result from
video_unregister_device being called before video_register_device.
Lastly, it simplifies access to the stk_webcam struct in several
places. This patch should apply cleanly against the "working" branch
of the v4l-dvb git repository.
This patch is identical to the patch I sent a couple of months back

rebased against current modifications to stk-webcam and it no longer

From the author:
This patch-set fixes remote control issues I have experienced
with hauppauge drivers in Linux since the PVR-350 and now
with both a NOVA-S+ and HVR-4000. It has also been confirmed
to work with an HVR-1300 user who had exactly the same issue.
Hauppage remote controls use RC5. RC5 has a bit-field which
represents the target device. The hauppauge windows drivers
have a registry key which can enable filtering, but the linux
drivers will accept any target device in this bit field for
internal processing.
This causes problems with setups such as mythtv where remote
control key presses destined for the TV (target = 0) are
interpreted by the kernel and subsequenctly LIRC then mythtv.
Of the remote controls I have to hand (wintv black, pvr/hvr
silver) the hauppauge remotes send one of two device targets
ids, these are interpreted by the patch which then filters
out any non hauppauge addresses.

SET_TONE and SET_VOLTAGE were not previously implemented. Two options
existed. Either cut/paste from the previous ioctl handler into the
process_properties function, which is code duplication. Or, split
the current ioctl handler into it's two major pieces.
Piece 1, responsible for input validation and semaphore acquiring
Piece 2 the processing of the previous ioctls
and finally, a new third pieces where the array of properties
is processed, and can freely call the legacy ioctl handler without
having to re-acquire the fepriv->sem semaphore. This is a clean approach
and ensures the existing legacy ioctls are processed as they were previously
(but with an extra function call) and allows the new API to share code
without duplication.

This is an experimental patch to add a new tuning mechanism for
dvb frontends. Rather than passing fixed structures across the
user/kernel boundary, which need to be revised for each new modulation
type (or feature the kernel developers want to add), this implements
a simpler message based approach, allowing fe commands to be broken
down into a series of small fixed size transactions, presented
in an array.
The goal is to avoid changing the user/kernel ABI in the future, by
simply creating new frontend commands (and sequencies of commands) that
help us add support for brand new demodulator, delivery system or
statistics related commmands.
known issues:
checkpatch voilations
feedback from various developers yet to be implemented, relating
to namespace conventions, variable length array passing conventions,
and generally some optimization.
This patch should support all existing tuning mechanisms through the
new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

When changing the standard the saa6752hs was not updated unless the input
was the TV tuner. The saa6752hs should be updated regardless of the input.
In addition the S_STD and G_STD ioctls for the mpeg video device didn't do
anything. This is now fixed: they behave just like S_STD and G_STD on the
video0 device.

cx18: Increment u8 pointers not void pointers. Incrementing void pointers
is dubious and the real intent in cx18_memcpy_fromio() and cx18_memset_io() is
to increment by bytes, so use u8 pointers instead.

cx18: Throttle mmio to/from the CX23418 so boards work in older systems. The
CX23418 couldn't reliably handle mmio at the rate at which the cx18 driver was
attempting to access the chip. The PCI bridge arrangements and settings on
modern motherboards still allowed the CX23418 to work OK, but it didn't work
well on many older motherboards: mysterious I2C errors, firmware loading errors,
etc. This patch adds a throttle to *all* mmio access to the CX23418. It
defaults to a delay of 31 ns, but is adjustable by the mmio_ndelay module parm.
My HVR-1600 and Raptor PAL/SECAM card now function for analog capture on a
motherboard with an Intel 82810E Northbridge and 82801AA Southbridge.

space register setting that was errantly borrowed from ivtv.

This builds upon the previous pvrusb2 change to more formally
implement full cropping support. This enables access from the
driver's V4L interface, and enables access to full capabilities from
sysfs as well. Note that this is only effective when in analog mode.
It also will only work when the underlying digitizer's driver (saa7115
or cx25840 depending on the hardware) also implements the appropriate
functions.

The earlier change from Hans Verkuil that pushed the BKL from
video_open() down into the drivers should be unneeded for the pvrusb2
driver. This driver's implementation for open already protects its
internal structures through other means, thus the BKL is not required.
This change reverses Hans' previous change, for the pvrusb2 driver.
It probably would have been a good idea for Hans to previously have
asked for my ack before committing his change.

When the input is set to tuner and no antenna is connected, the BT848
can flood VPRES interrupts. So we don't want to enable this type of
interrupts when the input it set to tuner.
As we don't do anything when receiving such an interrupt anyway, the
easiest fix is to simply not unmask this specific interrupt.

b) The tuner callback previously checked the command 3 times:
1) To see if it was the XC2028_RESET_CLK
2) To see if it was not the XC2028_RESET_TUNER
3) To see if it was the XC2028_RESET_TUNER
This patch removes the third check.
