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. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (831 commits) [media] cx88: make core less verbose [media] em28xx: fix oops at em28xx_dvb_bus_ctrl() [media] s5c73m3: fix indentation of the help section in Kconfig [media] cx25821-alsa: get rid of a __must_check warning [media] cx25821-video: declare cx25821_vidioc_s_std as static [media] cx25821-video: remove maxw from cx25821_vidioc_try_fmt_vid_cap [media] r820t: Remove a warning for an unused value [media] dib0090: Fix a warning at dib0090_set_EFUSE [media] dib8000: fix a warning [media] dib8000: Fix sub-channel range [media] dib8000: store dtv_property_cache in a temp var [media] dib8000: warning fix: declare internal functions as static [media] r820t: quiet gcc warning on n_ring [media] r820t: memory leak in release() [media] r820t: precendence bug in r820t_xtal_check() [media] videodev2.h: Remove the unused old V4L1 buffer types [media] anysee: Grammar s/report the/report to/ [media] anysee: Initialize ret = 0 in anysee_frontend_attach() [media] media: videobuf2: fix the length check for mmap [media] em28xx: save isoc endpoint number for DVB only if endpoint has alt settings with xMaxPacketSize != 0 ...

+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.

+Common bindings for video receiver and transmitter interfaces
+
+General concept
+---------------
+
+Video data pipelines usually consist of external devices, e.g. camera sensors,
+controlled over an I2C, SPI or UART bus, and SoC internal IP blocks, including
+video DMA engines and video data processors.
+
+SoC internal blocks are described by DT nodes, placed similarly to other SoC
+blocks. External devices are represented as child nodes of their respective
+bus controller nodes, e.g. I2C.
+
+Data interfaces on all video devices are described by their child 'port' nodes.
+Configuration of a port depends on other devices participating in the data
+transfer and is described by 'endpoint' subnodes.
+
+device {
+ ...
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ ...
+ endpoint@0 { ... };
+ endpoint@1 { ... };
+ };
+ port@1 { ... };
+ };
+};
+
+If a port can be configured to work with more than one remote device on the same
+bus, an 'endpoint' child node must be provided for each of them. If more than
+one port is present in a device node or there is more than one endpoint at a
+port, or port node needs to be associated with a selected hardware interface,
+a common scheme using '#address-cells', '#size-cells' and 'reg' properties is
+used.
+
+All 'port' nodes can be grouped under optional 'ports' node, which allows to
+specify #address-cells, #size-cells properties independently for the 'port'
+and 'endpoint' nodes and any child device nodes a device might have.
+
+Two 'endpoint' nodes are linked with each other through their 'remote-endpoint'
+phandles. An endpoint subnode of a device contains all properties needed for
+configuration of this device for data exchange with other device. In most
+cases properties at the peer 'endpoint' nodes will be identical, however they
+might need to be different when there is any signal modifications on the bus
+between two devices, e.g. there are logic signal inverters on the lines.
+
+It is allowed for multiple endpoints at a port to be active simultaneously,
+where supported by a device. For example, in case where a data interface of
+a device is partitioned into multiple data busses, e.g. 16-bit input port
+divided into two separate ITU-R BT.656 8-bit busses. In such case bus-width
+and data-shift properties can be used to assign physical data lines to each
+endpoint node (logical bus).
+
+
+Required properties
+-------------------
+
+If there is more than one 'port' or more than one 'endpoint' node or 'reg'
+property is present in port and/or endpoint nodes the following properties
+are required in a relevant parent node:
+
+ - #address-cells : number of cells required to define port/endpoint
+ identifier, should be 1.
+ - #size-cells : should be zero.
+
+Optional endpoint properties
+----------------------------
+
+- remote-endpoint: phandle to an 'endpoint' subnode of a remote device node.
+- slave-mode: a boolean property indicating that the link is run in slave mode.
+ The default when this property is not specified is master mode. In the slave
+ mode horizontal and vertical synchronization signals are provided to the
+ slave device (data source) by the master device (data sink). In the master
+ mode the data source device is also the source of the synchronization signals.
+- bus-width: number of data lines actively used, valid for the parallel busses.
+- data-shift: on the parallel data busses, if bus-width is used to specify the
+ number of data lines, data-shift can be used to specify which data lines are
+ used, e.g. "bus-width=<8>; data-shift=<2>;" means, that lines 9:2 are used.
+- hsync-active: active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
+- vsync-active: active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.
+ Note, that if HSYNC and VSYNC polarities are not specified, embedded
+ synchronization may be required, where supported.
+- data-active: similar to HSYNC and VSYNC, specifies data line polarity.
+- field-even-active: field signal level during the even field data transmission.
+- pclk-sample: sample data on rising (1) or falling (0) edge of the pixel clock
+ signal.
+- data-lanes: an array of physical data lane indexes. Position of an entry
+ determines the logical lane number, while the value of an entry indicates
+ physical lane, e.g. for 2-lane MIPI CSI-2 bus we could have
+ "data-lanes = <1 2>;", assuming the clock lane is on hardware lane 0.
+ This property is valid for serial busses only (e.g. MIPI CSI-2).
+- clock-lanes: an array of physical clock lane indexes. Position of an entry
+ determines the logical lane number, while the value of an entry indicates
+ physical lane, e.g. for a MIPI CSI-2 bus we could have "clock-lanes = <0>;",
+ which places the clock lane on hardware lane 0. This property is valid for
+ serial busses only (e.g. MIPI CSI-2). Note that for the MIPI CSI-2 bus this
+ array contains only one entry.
+- clock-noncontinuous: a boolean property to allow MIPI CSI-2 non-continuous
+ clock mode.
+
+
+Example
+-------
+
+The example snippet below describes two data pipelines. ov772x and imx074 are
+camera sensors with a parallel and serial (MIPI CSI-2) video bus respectively.
+Both sensors are on the I2C control bus corresponding to the i2c0 controller
+node. ov772x sensor is linked directly to the ceu0 video host interface.
+imx074 is linked to ceu0 through the MIPI CSI-2 receiver (csi2). ceu0 has a
+(single) DMA engine writing captured data to memory. ceu0 node has a single
+'port' node which may indicate that at any time only one of the following data
+pipelines can be active: ov772x -> ceu0 or imx074 -> csi2 -> ceu0.

+SI476x Driver Readme
+------------------------------------------------
+ Copyright (C) 2013 Andrey Smirnov <andrew.smirnov@gmail.com>
+
+TODO for the driver
+------------------------------
+
+- According to the SiLabs' datasheet it is possible to update the
+ firmware of the radio chip in the run-time, thus bringing it to the
+ most recent version. Unfortunately I couldn't find any mentioning of
+ the said firmware update for the old chips that I tested the driver
+ against, so for chips like that the driver only exposes the old
+ functionality.
+
+
+Parameters exposed over debugfs
+-------------------------------
+SI476x allow user to get multiple characteristics that can be very
+useful for EoL testing/RF performance estimation, parameters that have
+very little to do with V4L2 subsystem. Such parameters are exposed via
+debugfs and can be accessed via regular file I/O operations.
+
+The drivers exposes following files:
+
+* /sys/kernel/debug/<device-name>/acf
+ This file contains ACF(Automatically Controlled Features) status
+ information. The contents of the file is binary data of the
+ following layout:
