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.

43Example:
44
45SoC specific DT entry:
46
47 fimd@11c00000 {
48 compatible = "samsung,exynos4210-fimd";
49 interrupt-parent = <&combiner>;
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 };
58
59Board specific DT entry:
60
61 fimd@11c00000 {
62 pinctrl-0 = <&lcd_clk &lcd_data24 &pwm1_out>;
63 pinctrl-names = "default";
64 status = "okay";
65 };
