Device-Tree bindings for Samsung SoC display controller (FIMD)

FIMD (Fully Interactive Mobile Display) is the Display Controller for the
Samsung series of SoCs which transfers the image data from a video memory
buffer to an external LCD interface.

Required properties:

• compatible: value should be one of the following

    "samsung,s3c2443-fimd"; /* for S3C24XX SoCs */
    "samsung,s3c6400-fimd"; /* for S3C64XX SoCs */
    "samsung,s5p6440-fimd"; /* for S5P64X0 SoCs */
    "samsung,s5pc100-fimd"; /* for S5PC100 SoC  */
    "samsung,s5pv210-fimd"; /* for S5PV210 SoC */
    "samsung,exynos4210-fimd"; /* for Exynos4 SoCs */
    "samsung,exynos5250-fimd"; /* for Exynos5 SoCs */
  

• reg: physical base address and length of the FIMD registers set.

• interrupt-parent: should be the phandle of the fimd controller’s

    parent interrupt controller.
  

• interrupts: should contain a list of all FIMD IP block interrupts in the

     order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
     format depends on the interrupt controller used.
  

• interrupt-names: should contain the interrupt names: “fifo”, “vsync”,
  “lcd_sys”, in the same order as they were listed in the interrupts

    property.
  

• pinctrl-0: pin control group to be used for this controller.

• pinctrl-names: must contain a “default” entry.

• clocks: must include clock specifiers corresponding to entries in the

     clock-names property.
  

• clock-names: list of clock names sorted in the same order as the clocks

           property. Must contain "sclk_fimd" and "fimd".
  

Optional Properties:

• samsung,power-domain: a phandle to FIMD power domain node.

Example:

SoC specific DT entry:

fimd@11c00000 {
    compatible = "samsung,exynos4210-fimd";
    interrupt-parent = <&combiner>;
    reg = <0x11c00000 0x20000>;
    interrupt-names = "fifo", "vsync", "lcd_sys";
    interrupts = <11 0>, <11 1>, <11 2>;
    clocks = <&clock 140>, <&clock 283>;
    clock-names = "sclk_fimd", "fimd";
    samsung,power-domain = <&pd_lcd0>;
    status = "disabled";
};

Board specific DT entry:

fimd@11c00000 {
    pinctrl-0 = <&lcd_clk &lcd_data24 &pwm1_out>;
    pinctrl-names = "default";
    status = "okay";
};
