-Device-Tree bindings for Samsung Exynos7 SoC display controller (DECON)
-
-DECON (Display and Enhancement Controller) is the Display Controller for the
-Exynos7 series of SoCs which transfers the image data from a video memory
-buffer to an external LCD interface.
-
-Required properties:
-- compatible: value should be "samsung,exynos7-decon";
-
-- reg: physical base address and length of the DECON registers set.
-
-- interrupts: should contain a list of all DECON 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 "pclk_decon0", "aclk_decon0",
- "decon0_eclk", "decon0_vclk".
-- i80-if-timings: timing configuration for lcd i80 interface support.
-
-Optional Properties:
-- power-domains: a phandle to DECON power domain node.
-- display-timings: timing settings for DECON, as described in document [1].
- Can be used in case timings cannot be provided otherwise
- or to override timings provided by the panel.

-Example:
-
-SoC specific DT entry:
-
- decon@13930000 {
- compatible = "samsung,exynos7-decon";
- interrupt-parent = <&combiner>;
- reg = <0x13930000 0x1000>;
- interrupt-names = "lcd_sys", "vsync", "fifo";
- interrupts = <0 188 0>, <0 189 0>, <0 190 0>;
- clocks = <&clock_disp PCLK_DECON_INT>,
- <&clock_disp ACLK_DECON_INT>,
- <&clock_disp SCLK_DECON_INT_ECLK>,
- <&clock_disp SCLK_DECON_INT_EXTCLKPLL>;
- clock-names = "pclk_decon0", "aclk_decon0", "decon0_eclk",
- "decon0_vclk";
- status = "disabled";
- };
-
-Board specific DT entry:
-
- decon@13930000 {
- pinctrl-0 = <&lcd_clk &pwm1_out>;
- pinctrl-names = "default";
- status = "okay";
- };
