This is a quite large renaming to consolidate display related bindings into a single "display" directory from various scattered locations of video, drm, gpu, fb, mipi, and panel. The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.

Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
|
|
|
|
DECON (Display and Enhancement Controller) is the Display Controller for the
|
|
Exynos 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,exynos5433-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: VSYNC, LCD_SYSTEM. The interrupt specifier format
|
|
depends on the interrupt controller used.
|
|
- interrupt-names: should contain the interrupt names: "vsync", "lcd_sys"
|
|
in the same order as they were listed in the interrupts
|
|
property.
|
|
- 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 "aclk_decon", "aclk_smmu_decon0x",
|
|
"aclk_xiu_decon0x", "pclk_smmu_decon0x", clk_decon_vclk",
|
|
"sclk_decon_eclk"
|
|
- ports: contains a port which is connected to mic node. address-cells and
|
|
size-cells must 1 and 0, respectively.
|
|
- port: contains an endpoint node which is connected to the endpoint in the mic
|
|
node. The reg value muset be 0.
|
|
- i80-if-timings: specify whether the panel which is connected to decon uses
|
|
i80 lcd interface or mipi video interface. This node contains
|
|
no timing information as that of fimd does. Because there is
|
|
no register in decon to specify i80 interface timing value,
|
|
it is not needed, but make it remain to use same kind of node
|
|
in fimd and exynos7 decon.
|
|

SoC specific DT entry:
|
|
decon: decon@13800000 {
|

<&cmu_disp CLK_SCLK_DECON_VCLK>,
|
|
<&cmu_disp CLK_SCLK_DECON_ECLK>;
|
|
clock-names = "aclk_decon", "aclk_smmu_decon0x", "aclk_xiu_decon0x",
|
|
"pclk_smmu_decon0x", "sclk_decon_vclk", "sclk_decon_eclk";
|
|
interrupt-names = "vsync", "lcd_sys";
|
|
interrupts = <0 202 0>, <0 203 0>;
|
|
|
|
ports {
|
|
#address-cells = <1>;
