dt-bindings: display: samsung,exynos5433-decon: convert to dtschema
Convert the Exynos5433 DECON display controller bindings to DT schema format. The conversion includes also updates to the bindings, matching the current DTS and Linux driver: 1. Require "fifo" interrupt. 2. Add "dsd" as a last clock. 3. Document "power-domains" and "iommus" properties.

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 one of:
|
||||
"samsung,exynos5433-decon", "samsung,exynos5433-decon-tv";
|
||||
- reg: physical base address and length of the DECON registers set.
|
||||
- interrupt-names: should contain the interrupt names depending on mode of work:
|
||||
video mode: "vsync",
|
||||
command mode: "lcd_sys",
|
||||
command mode with software trigger: "lcd_sys", "te".
|
||||
- interrupts or interrupts-extended: list of interrupt specifiers corresponding
|
||||
to names privided in interrupt-names, as described in
|
||||
interrupt-controller/interrupts.txt
|
||||
- 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", "aclk_decon", "aclk_smmu_decon0x",
|
||||
"aclk_xiu_decon0x", "pclk_smmu_decon0x", "aclk_smmu_decon1x",
|
||||
"aclk_xiu_decon1x", "pclk_smmu_decon1x", 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.
|
||||
|
||||
Example:
|
||||
SoC specific DT entry:
|
||||
decon: decon@13800000 {
|
||||
compatible = "samsung,exynos5433-decon";
|
||||
reg = <0x13800000 0x2104>;
|
||||
clocks = <&cmu_disp CLK_ACLK_DECON>, <&cmu_disp CLK_ACLK_SMMU_DECON0X>,
|
||||
<&cmu_disp CLK_ACLK_XIU_DECON0X>,
|

<&cmu_disp CLK_PCLK_SMMU_DECON0X>,
|

<&cmu_disp CLK_ACLK_SMMU_DECON1X>,
|

<&cmu_disp CLK_ACLK_XIU_DECON1X>,
|
||||
<&cmu_disp CLK_PCLK_SMMU_DECON1X>,
|
||||
<&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", "aclk_smmu_decon1x", "aclk_xiu_decon1x",
|
||||
"pclk_smmu_decon1x", "sclk_decon_vclk", "sclk_decon_eclk";
|
||||
interrupt-names = "vsync", "lcd_sys";
|
||||
interrupts = <0 202 0>, <0 203 0>;
|
||||
|
||||
ports {
|
||||
#address-cells = <1>;
