V4L/DVB: tvp7002: fix write to H-PLL Feedback Divider LSB register
H-PLL Feedback Divider LSB register is an 8 bit register out
of which the first 4 bits are reserved. Current code is
writing to these reserved location. This patch corrects
this issue by left shifting the values being written to the
register by 4.
This patch has been tested on DM6467 EVM with 720P-60 and
1080I-60 inputs.
V4L/DVB: dvb: siano: free spinlock before schedule()
Calling schedule() holding spinlock with disables irqs is improper. As

This bug was introduced in a9349315f65cd6a16e8fab1f6cf0fd40f379c4db.
Here a small patch to get a TwinHan VT DST DVB-T card working with
kernels >= 2.6.32. Analogously to
http://linuxtv.org/hg/v4l-dvb/rev/0e735b509163 I had to:
"Fill in the .caps field in struct dst_dvbt_ops (around line 1763) with
all the supported QAM modulation methods to match the capabilities of
the card as implemented in function dst_set_modulation (around line
502). Note that beginning with linux kernel version 2.6.32 the
modulation method is checked (by function dvb_frontend_check_parameters
in file drivers/media/dvb/dvb-core/dvb_frontend.c) and thus tuning fails
if you use a modulation method that is not present in the .caps field."

Since this module is also used by drivers that are not yet converted, the old

The source is split into three parts: a common part at the top, which is used

than the original code.
Once all bridge drivers that use this are converted the old code can be

V4L/DVB: v4l2: Add new control handling framework
Add a new framework to handle controls which makes life for driver
developers much easier.
Note that this patch moves some of the control support that used to be in
v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body
of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function
in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl
struct anymore, which makes it more general.
The remainder of v4l2-ctrls.c is all new. Highlights include:
- No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL,
S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers
or subdevs. New wrapper functions are provided that can just be plugged in.
Once everything has been converted these wrapper functions can be removed as well.
- When subdevices are added their controls can be automatically merged
with the bridge driver's controls.
- Most drivers just need to implement s_ctrl to set the controls.
The framework handles the locking and tries to be as 'atomic' as possible.
- Ready for the subdev device nodes: the same mechanism applies to subdevs
and their device nodes as well. Sub-device drivers can make controls
local, preventing them from being merged with bridge drivers.
- Takes care of backwards compatibility handling of VIDIOC_S_CTRL and
VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent.
CTRL_CLASS controls are automatically added.

a patch moving the driver over to drivers/media/IR/streamzap.c and

Presently, the in-kernel keymap doesn't work, as the stock Streamzap
remote uses an RC-5-like, but not-quite-RC-5 protocol, which the
in-kernel RC-5 decoder doesn't cope with. The remote can be used right
now with the lirc bridge driver though, and other remotes (at least an
RC-6(A) MCE remote) work perfectly with the driver.
I'll take a look at making the existing RC-5 decoder cope with this odd
duck, possibly implement another standalone decoder engine, or just
throw up my hands and say "meh, use lirc"... But the driver itself
should be perfectly sound.
Remaining items on the streamzap TODO list:
- add LIRC_SET_REC_TIMEOUT-alike support
- add LIRC_GET_M{AX,IN}_TIMEOUT-alike support
- add LIRC_GET_REC_RESOLUTION-alike support
All of the above should be trivial to add. There are patches pending to

sending Audio and Video interrupts to the bridge driver. For
CX2388[578] chips audio and video interrupts are ignored and
acknowledged when they happen.
IR interrupt handling and status logging is exluded for the CX23888
