Subject: V4L/DVB (13633): ir-core: create a new class for remote controllers

Add sysfs skeleton to export remote controller information via
/sys/class/irrcv.

For now, the code doesn't do much. It just exports an attribute that
is meant to  report and control the IR protocol used by the keytable.
However, the callbacks for this new attribute weren't set yet.

Also, it lacks symlinks to the used event interface.

Subject: V4L/DVB (13634): ir-core: allow passing IR device parameters to
 ir-core

Adds an structure to ir_input_register to contain IR device characteristics,
like supported protocols and a callback to handle protocol event changes.

Subject: V4L/DVB (13680): ir: use unsigned long instead of enum
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When preparing the linux-next patches, I got those errors:

include/media/ir-core.h:29: warning: left shift count >= width of type
In file included from include/media/ir-common.h:29,
                 from drivers/media/video/ir-kbd-i2c.c:50:
drivers/media/video/ir-kbd-i2c.c: In function ‘ir_probe’:
drivers/media/video/ir-kbd-i2c.c:324: warning: left shift count >= width of type

Unfortunately, enum is 32 bits on i386. As we define IR_TYPE_OTHER as 1<<63,
it won't work on non 64 bits arch.

From: Hans de Goede <hdegoede@redhat.com>
Date: Thu, 14 Jan 2010 09:37:18 -0300
Subject: V4L/DVB (14003): gspca_cpai1: New gspca subdriver for CPIA CPiA
 version 1 cams

This new driver supports USB PIA CPiA version 1 cams, replacing the
old v4l1 driver.

From 3ccc646b56a3f03029a259c6a8affd9cecc6020e Mon Sep 17 00:00:00 2001

Subject: V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny
 audio

This change attempts to fix the ivtv tinny audio problem by keeping digitizer
to encoder audio clocks running, while disabling the video clocks as needed to
avoid unpredictable PCI bus hangs.

To accomplish this, for the cx25840 module enabling of audio streaming had
to be separated from enabling video streaming, requiring an additional
v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers.

The cx231xx and cx23885 driver use the cx25840 module for affecting only
video on s_stream calls, so those drivers needed no change.

The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI
bus hang, so the cx18 driver did not need corresponding changes.

CX2341[56] based cards that are not using the CX2584x family of chips
do not seem to be affected by the tinny audio problem, and this change should
not affect how they are configured. It will delay their first capture by
starting by another 300 msec though.

Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and
Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and
investigation of this problem will hopefully fix this problem once and for all
for many ivtv users.

Subject: V4L/DVB: radio: add support for SAA7706H Car Radio DSP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Initial support for the SAA7706H Car Radio DSP.

It is a I2C device and currently the mute control is supported.

When the device is unmuted it is brought out of reset and initiated using
the proposed intialisation sequence.

When muted the DSP is brought into reset state.

From: Richard Röjfors <richard.rojfors@pelagicore.com>

Subject: V4L/DVB: radio: Add radio-timb
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch add supports for the radio system on the Intel Russellville board.

It's a In-Vehicle Infotainment board with a radio tuner and DSP.

This umbrella driver has the DSP and tuner as V4L2 subdevs and calls them
when needed.

Subject: soc-camera: ov772x: Modify buswidth control

This patch removes "buswidth" struct member, and sets the default buswidth
to the natively supported 10 bit. You can select 8 bit buswidth by new flag.
This patch also modify ap325rxa/migor setup.c

Subject: V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered
 too late

v4l2_device_register needs to be called before the i2c subdevs are loaded.
However, it was called afterwards in the saa7146 driver. This caused an oops
when loading the mxb and hexium drivers. The vv_init function is now split
into two: one registers the v4l2_device, the other does the rest of the
initialization. The three drivers that depend on this have been updated to
call the new vv_devinit function.

Thanks to Michael Hunold for reporting this.

Subject: V4L/DVB: saa7115: fix saa7111a support

When the saa7111 driver was merged into saa7115 several bugs were introduced,
in particular with the saa7111a support as is used in the mxb.c driver.
This patch fixes the saa7111a support. This was tested with the mxb driver.

Subject: V4L/DVB: V4L - vpfe capture - header files for ISIF driver

This is the header file for ISIF driver on DM365.  ISIF driver is equivalent
to CCDC driver on DM355 and DM644x. This driver is tested for
YUV capture from TVP514x driver. This patch contains the header files required
for this driver.

Subject: V4L/DVB: V4L - vpfe capture - vpss driver enhancements for DM365

Enhancements to support DM365 ISP5 and VPSS module configuration.
Also cleaned up the driver by removing redundant variables.

Subject: V4L/DVB: tuner-types: Add Sony BTF-Pxn01Z tuner type used on
 GigaPocket cards

Sony makes custome tuners for its GigaPocket line of ivtv based capture
cards.  This adds an entry to the tuner-types list for such tuners.
Parameters are based on experiments by Eric Anderson <rico99@sbcglobal.net>.
