Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media 

Pull media updates from Mauro Carvalho Chehab:
 - removal of sn9c102.  This device driver was replaced a long time ago
   by gspca
 - solo6x10 and go7007 webcam drivers moved from staging into
   mainstream.  They were waiting for an API to allow setting the image
   detection matrix
 - SDR drivers moved from staging into mainstream: sdr-msi3101 (renamed
   as msi2500) and rtl2832
 - added SDR driver for airspy
 - added demux driver: si2165
 - rework at several RC subsystem, making the code for RC-5 SZ variant
   to be added at the standard RC5 decoder
 - added decoder for the XMP IR protocol
 - tuner driver moved from staging into mainstream: msi3101 (renamed as
   msi001)
 - added documentation for some additional SDR pixfmt
 - some device tree bindings documented
 - added support for exynos3250 at s5p-jpeg
 - remove the obsolete, unmaintained and broken mx1_camera driver
 - added support for remote controllers at au0828 driver
 - added a RC driver: sunxi-cir
 - several driver fixes, enhancements and cleanups.

Renesas RCar Video Input driver (rcar_vin)
------------------------------------------
The rcar_vin device provides video input capabilities for the Renesas R-Car
family of devices. The current blocks are always slaves and suppot one input
channel which can be either RGB, YUYV or BT656.
- compatible: Must be one of the following
- "renesas,vin-r8a7791" for the R8A7791 device
- "renesas,vin-r8a7790" for the R8A7790 device
- "renesas,vin-r8a7779" for the R8A7779 device
- "renesas,vin-r8a7778" for the R8A7778 device
- reg: the register base and size for the device registers
- interrupts: the interrupt for the device
- clocks: Reference to the parent clock
Additionally, an alias named vinX will need to be created to specify
which video input device this is.
The per-board settings:
- port sub-node describing a single endpoint connected to the vin
as described in video-interfaces.txt[1]. Only the first one will
be considered as each vin interface has one input port.
These settings are used to work out video input format and widths
into the system.
Device node example

Accessing Control Values
========================
The v4l2_ctrl struct contains these two unions:
The following union is used inside the control framework to access control
values:
/* The current control value. */
union {
union v4l2_ctrl_ptr {
s32 *p_s32;
s64 *p_s64;
char *p_char;
void *p;
};
The v4l2_ctrl struct contains these fields that can be used to access both
current and new values:
s32 val;
struct {
s32 val;
s64 val64;
char *string;
} cur;
/* The new control value. */
union {
s32 val;
s64 val64;
char *string;
};
Within the control ops you can freely use these. The val and val64 speak for
themselves. The string pointers point to character buffers of length
union v4l2_ctrl_ptr p_new;
union v4l2_ctrl_ptr p_cur;
If the control has a simple s32 type type, then:
&ctrl->val == ctrl->p_new.p_s32
&ctrl->cur.val == ctrl->p_cur.p_s32
For all other types use ctrl->p_cur.p<something>. Basically the val
and cur.val fields can be considered an alias since these are used so often.
Within the control ops you can freely use these. The val and cur.val speak for
themselves. The p_char pointers point to character buffers of length
ctrl->maximum + 1, and are always 0-terminated.
In most cases 'cur' contains the current cached control value. When you create
a new control this value is made identical to the default value. After calling
v4l2_ctrl_handler_setup() this value is passed to the hardware. It is generally
a good idea to call this function.
Unless the control is marked volatile the p_cur field points to the the
current cached control value. When you create a new control this value is made
identical to the default value. After calling v4l2_ctrl_handler_setup() this
value is passed to the hardware. It is generally a good idea to call this
function.
Whenever a new value is set that new value is automatically cached. This means

* Table to estimate signal strength in dBm.

* This table was determinated by measuring the signal strength generated
* by a DTA-2111 RF generator directly connected into a dib7000p device
* (a Hauppauge Nova-TD stick), using a good quality 3 meters length
* RC6 cable and good RC6 connectors, connected directly to antenna 1.
* As the minimum output power of DTA-2111 is -31dBm, a 16 dBm attenuator
* were used, for the lower power values.
* The real value can actually be on other devices, or even at the
* second antena input, depending on several factors, like if LNA
* is enabled or not, if diversity is enabled, type of connectors, etc.
* Yet, it is better to use this measure in dB than a random non-linear
* percentage value, especially for antenna adjustments.
* On my tests, the precision of the measure using this table is about
* 0.5 dB, with sounds reasonable enough to adjust antennas.
