   1 Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
   2
   3 DECON (Display and Enhancement Controller) is the Display Controller for the
   4 Exynos series of SoCs which transfers the image data from a video memory
   5 buffer to an external LCD interface.
   6
   7 Required properties:
   8 - compatible: value should be one of:
   9         "samsung,exynos5433-decon", "samsung,exynos5433-decon-tv";
  10 - reg: physical base address and length of the DECON registers set.
  11 - interrupt-names: should contain the interrupt names depending on mode of work:
  12                 video mode: "vsync",
  13                 command mode: "lcd_sys",
  14                 command mode with software trigger: "lcd_sys", "te".
  15 - interrupts or interrupts-extended: list of interrupt specifiers corresponding
  16                 to names privided in interrupt-names, as described in
  17                 interrupt-controller/interrupts.txt
  18 - clocks: must include clock specifiers corresponding to entries in the
  19           clock-names property.
  20 - clock-names: list of clock names sorted in the same order as the clocks
  21                property. Must contain "pclk", "aclk_decon", "aclk_smmu_decon0x",
  22                "aclk_xiu_decon0x", "pclk_smmu_decon0x", clk_decon_vclk",
  23                "sclk_decon_eclk"
  24 - ports: contains a port which is connected to mic node. address-cells and
  25          size-cells must 1 and 0, respectively.
  26 - port: contains an endpoint node which is connected to the endpoint in the mic
  27         node. The reg value muset be 0.
