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. [1]: Documentation/devicetree/bindings/display/panel/display-timing.txt 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"; };
