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

Pull media update from Mauro Carvalho Chehab:

 - OF documentation and patches at core and drivers, to be used by for
   embedded media systems

 - some I2C drivers used on go7007 were rewritten/promoted from staging:
   sony-btf-mpx, tw2804, tw9903, tw9906, wis-ov7640, wis-uda1342

 - add fimc-is driver (Exynos)

 - add a new radio driver: radio-si476x

 - add a two new tuners: r820t and tuner_it913x

 - split camera code on em28xx driver and add more models

 - the cypress firmware load is used outside dvb usb drivers.  So, move
   it to a common directory to make easier to re-use it

 - siano media driver updated to work with sms2270 devices

 - several work done in order to promote go7007 and solo6x1x out of
   staging (still, there are some pending issues)

 - several API compliance fixes at v4l2 drivers that don't behave as
   expected

 - as usual, lots of driver fixes, improvements, cleanups and new device
   addition at the existing drivers.

+Samsung S5P/EXYNOS SoC Camera Subsystem (FIMC)
+----------------------------------------------
+
+The S5P/Exynos SoC Camera subsystem comprises of multiple sub-devices
+represented by separate device tree nodes. Currently this includes: FIMC (in
+the S5P SoCs series known as CAMIF), MIPI CSIS, FIMC-LITE and FIMC-IS (ISP).
+
+The sub-subdevices are defined as child nodes of the common 'camera' node which
+also includes common properties of the whole subsystem not really specific to
+any single sub-device, like common camera port pins or the CAMCLK clock outputs
+for external image sensors attached to an SoC.
+
+Common 'camera' node
+--------------------
+
+Required properties:
+
+- compatible	: must be "samsung,fimc", "simple-bus"
+- clocks	: list of clock specifiers, corresponding to entries in
+		  the clock-names property;
+- clock-names	: must contain "sclk_cam0", "sclk_cam1", "pxl_async0",
+		  "pxl_async1" entries, matching entries in the clocks property.
+
+The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
+to define a required pinctrl state named "default" and optional pinctrl states:
+"idle", "active-a", active-b". These optional states can be used to switch the
+camera port pinmux at runtime. The "idle" state should configure both the camera
+ports A and B into high impedance state, especially the CAMCLK clock output
+should be inactive. For the "active-a" state the camera port A must be activated
+and the port B deactivated and for the state "active-b" it should be the other
+way around.
+
+The 'camera' node must include at least one 'fimc' child node.
+
+'fimc' device nodes
+-------------------
+
+Required properties:
+
+- compatible: "samsung,s5pv210-fimc" for S5PV210, "samsung,exynos4210-fimc"
+  for Exynos4210 and "samsung,exynos4212-fimc" for Exynos4x12 SoCs;
+- reg: physical base address and length of the registers set for the device;
+- interrupts: should contain FIMC interrupt;
+- clocks: list of clock specifiers, must contain an entry for each required
+  entry in clock-names;
+- clock-names: must contain "fimc", "sclk_fimc" entries.
+- samsung,pix-limits: an array of maximum supported image sizes in pixels, for
+  details refer to Table 2-1 in the S5PV210 SoC User Manual; The meaning of
+  each cell is as follows:
+  0 - scaler input horizontal size,
+  1 - input horizontal size for the scaler bypassed,
+  2 - REAL_WIDTH without input rotation,
+  3 - REAL_HEIGHT with input rotation,
+- samsung,sysreg: a phandle to the SYSREG node.
+
+Each FIMC device should have an alias in the aliases node, in the form of
+fimc<n>, where <n> is an integer specifying the IP block instance.
+
+Optional properties:
+
+- clock-frequency: maximum FIMC local clock (LCLK) frequency;
+- samsung,min-pix-sizes: an array specyfing minimum image size in pixels at
+  the FIMC input and output DMA, in the first and second cell respectively.
+  Default value when this property is not present is <16 16>;
+- samsung,min-pix-alignment: minimum supported image height alignment (first
+  cell) and the horizontal image offset (second cell). The values are in pixels
+  and default to <2 1> when this property is not present;
+- samsung,mainscaler-ext: a boolean property indicating whether the FIMC IP
+  supports extended image size and has CIEXTEN register;
+- samsung,rotators: a bitmask specifying whether this IP has the input and
+  the output rotator. Bits 4 and 0 correspond to input and output rotator
+  respectively. If a rotator is present its corresponding bit should be set.
+  Default value when this property is not specified is 0x11.
+- samsung,cam-if: a bolean property indicating whether the IP block includes
+  the camera input interface.
+- samsung,isp-wb: this property must be present if the IP block has the ISP
+  writeback input.
+- samsung,lcd-wb: this property must be present if the IP block has the LCD
+  writeback input.
+
+
+'parallel-ports' node
+---------------------
+
+This node should contain child 'port' nodes specifying active parallel video
+input ports. It includes camera A and camera B inputs. 'reg' property in the
+port nodes specifies data input - 0, 1 indicates input A, B respectively.
+
+Optional properties
+
+- samsung,camclk-out : specifies clock output for remote sensor,
+		       0 - CAM_A_CLKOUT, 1 - CAM_B_CLKOUT;
+
+Image sensor nodes
+------------------
+
+The sensor device nodes should be added to their control bus controller (e.g.
+I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
+using the common video interfaces bindings, defined in video-interfaces.txt.
+The implementation of this bindings requires clock-frequency property to be
+present in the sensor device nodes.
+

+		fimc0 = &fimc_0;
