    Subject[PATCH v3 6/7] media: dt-bindings: samsung,fimc: convert to dtschema
    Date
    Convert the Samsung S5P/Exynos Camera Subsystem (FIMC) bindings to DT
    schema. Changes during conversion - adjust to existing DTS and Linux
    driver: add iommus and power-domains.

    Changes since v2:
    1. Add Rb tag.
    2. Move size-cells next to address-cells.

    The patch depends on:

    -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"
    -- 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.
    -
    -- #clock-cells: from the common clock bindings (../clock/clock-bindings.txt),
    - must be 1. A clock provider is associated with the 'camera' node and it should
    - be referenced by external sensors that use clocks provided by the SoC on
    - CAM_*_CLKOUT pins. The clock specifier cell stores an index of a clock.
    - The indices are 0, 1 for CAM_A_CLKOUT, CAM_B_CLKOUT clocks respectively.
    -
    -- clock-output-names: from the common clock bindings, should contain names of
    - clocks registered by the camera subsystem corresponding to CAM_A_CLKOUT,
    - CAM_B_CLKOUT output clocks respectively.
    -
    -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 - 1, 2 indicates input A, B respectively.
    -
    -Optional properties
    -
    -- samsung,camclk-out (deprecated) : 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.
