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.
- samsung,invert-vden: video enable signal is inverted
- samsung,invert-vclk: video clock signal is inverted
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";
};
