MIPI DSI is17 not capable of transferring high resoltuion frame data as DECON can send. MIC18 solves this problem by compressing the frame data by 1/2 before it is19 transferred through MIPI DSI. The compressed frame data must be uncompressed20 in the panel PCB.21 22properties:23 compatible:24 const: samsung,exynos5433-mic25 26 clocks:27 maxItems: 228 29 clock-names:30 items:31 - const: pclk_mic032 - const: sclk_rgb_vclk_to_mic033 34 ports:35 $ref: /schemas/graph.yaml#/properties/ports36 description:37 Contains a port which is connected to mic node.38 39 power-domains:40 maxItems: 141 42 reg:43 maxItems: 144 45 samsung,disp-syscon:46 $ref: /schemas/types.yaml#/definitions/phandle47 description:48 Phandle to DISP system controller interface.49 50required:51 - compatible52 - clocks53 - clock-names54 - ports55 - reg56 - samsung,disp-syscon57 58additionalProperties: false59 60examples:61 - |62 #include <dt-bindings/clock/exynos5433.h>63 #include <dt-bindings/interrupt-controller/arm-gic.h>64 65 image-processor@13930000 {66 compatible = "samsung,exynos5433-mic";67 reg = <0x13930000 0x48>;68 clocks = <&cmu_disp CLK_PCLK_MIC0>,69 <&cmu_disp CLK_SCLK_RGB_VCLK_TO_MIC0>;70 clock-names = "pclk_mic0",71 "sclk_rgb_vclk_to_mic0";72 power-domains = <&pd_disp>;73 samsung,disp-syscon = <&syscon_disp>;74 75 ports {76 #address-cells = <1>;77 #size-cells = <0>;78 79 port@0 {80 reg = <0>;81 mic_to_decon: endpoint {82 remote-endpoint = <&decon_to_mic>;83 };84 };85 86 port@1 {87 reg = <1>;88 mic_to_dsi: endpoint {89 remote-endpoint = <&dsi_to_mic>;90 };91 };92 };93 };94
