   1Device-Tree bindings for Samsung SoC display controller (FIMD)
   2
   3FIMD (Fully Interactive Mobile Display) is the Display Controller for the
   4Samsung series of SoCs which transfers the image data from a video memory
   5buffer to an external LCD interface.
   6
   7Required properties:
   8- compatible: value should be one of the following
   9                "samsung,s3c2443-fimd"; /* for S3C24XX SoCs */
  10                "samsung,s3c6400-fimd"; /* for S3C64XX SoCs */
  11                "samsung,s5p6440-fimd"; /* for S5P64X0 SoCs */
  12                "samsung,s5pc100-fimd"; /* for S5PC100 SoC  */
  13                "samsung,s5pv210-fimd"; /* for S5PV210 SoC */
  14                "samsung,exynos4210-fimd"; /* for Exynos4 SoCs */
  15                "samsung,exynos5250-fimd"; /* for Exynos5 SoCs */
  16
  17- reg: physical base address and length of the FIMD registers set.
  18
  19- interrupt-parent: should be the phandle of the fimd controller's
  20                parent interrupt controller.
  21
  22- interrupts: should contain a list of all FIMD IP block interrupts in the
  23                 order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
  24                 format depends on the interrupt controller used.
  25
  26- interrupt-names: should contain the interrupt names: "fifo", "vsync",
  27        "lcd_sys", in the same order as they were listed in the interrupts
  28        property.
  29
  30- pinctrl-0: pin control group to be used for this controller.
  31
  32- pinctrl-names: must contain a "default" entry.
  33
  34- clocks: must include clock specifiers corresponding to entries in the
  35         clock-names property.
  36
  37- clock-names: list of clock names sorted in the same order as the clocks
  38               property. Must contain "sclk_fimd" and "fimd".
  39
  40Optional Properties:
  41- samsung,power-domain: a phandle to FIMD power domain node.

  45SoC specific DT entry:
  46
  47        fimd@11c00000 {
  48                compatible = "samsung,exynos4210-fimd";

  50                reg = <0x11c00000 0x20000>;
  51                interrupt-names = "fifo", "vsync", "lcd_sys";
  52                interrupts = <11 0>, <11 1>, <11 2>;
  53                clocks = <&clock 140>, <&clock 283>;
  54                clock-names = "sclk_fimd", "fimd";
  55                samsung,power-domain = <&pd_lcd0>;
  56                status = "disabled";
  57        };

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