1 Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
3 DECON (Display and Enhancement Controller) is the Display Controller for the
4 Exynos series of SoCs which transfers the image data from a video memory
5 buffer to an external LCD interface.
8 - compatible: value should be one of:
9 "samsung,exynos5433-decon", "samsung,exynos5433-decon-tv";
10 - reg: physical base address and length of the DECON registers set.
11 - interrupt-names: should contain the interrupt names depending on mode of work:
13 command mode: "lcd_sys",
14 command mode with software trigger: "lcd_sys", "te".
15 - interrupts or interrupts-extended: list of interrupt specifiers corresponding
16 to names privided in interrupt-names, as described in
17 interrupt-controller/interrupts.txt
18 - clocks: must include clock specifiers corresponding to entries in the
20 - clock-names: list of clock names sorted in the same order as the clocks
21 property. Must contain "pclk", "aclk_decon", "aclk_smmu_decon0x",
22 "aclk_xiu_decon0x", "pclk_smmu_decon0x", clk_decon_vclk",
24 - ports: contains a port which is connected to mic node. address-cells and
25 size-cells must 1 and 0, respectively.
26 - port: contains an endpoint node which is connected to the endpoint in the mic
27 node. The reg value muset be 0.
28 - i80-if-timings: specify whether the panel which is connected to decon uses
29 i80 lcd interface or mipi video interface. This node contains
30 no timing information as that of fimd does. Because there is
31 no register in decon to specify i80 interface timing value,
32 it is not needed, but make it remain to use same kind of node
33 in fimd and exynos7 decon.
