MIPI DSI is 18 not capable of transferring high resoltuion frame data as DECON can send. MIC 19 solves this problem by compressing the frame data by 1/2 before it is 20 transferred through MIPI DSI. The compressed frame data must be uncompressed 21 in the panel PCB. 22 23properties: 24 compatible: 25 const: samsung,exynos5433-mic 26 27 clocks: 28 minItems: 2 29 maxItems: 2 30 31 clock-names: 32 items: 33 - const: pclk_mic0 34 - const: sclk_rgb_vclk_to_mic0 35 36 ports: 37 $ref: /schemas/graph.yaml#/properties/ports 38 description: 39 Contains a port which is connected to mic node. 40 41 power-domains: 42 maxItems: 1 43 44 reg: 45 maxItems: 1 46 47 samsung,disp-syscon: 48 $ref: /schemas/types.yaml#/definitions/phandle 49 description: 50 Phandle to DISP system controller interface. 51 52required: 53 - compatible 54 - clocks 55 - clock-names 56 - ports 57 - reg 58 - samsung,disp-syscon 59 60additionalProperties: false 61 62examples: 63 - | 64 #include <dt-bindings/clock/exynos5433.h> 65 #include <dt-bindings/interrupt-controller/arm-gic.h> 66 67 image-processor@13930000 { 68 compatible = "samsung,exynos5433-mic"; 69 reg = <0x13930000 0x48>; 70 clocks = <&cmu_disp CLK_PCLK_MIC0>, 71 <&cmu_disp CLK_SCLK_RGB_VCLK_TO_MIC0>; 72 clock-names = "pclk_mic0", 73 "sclk_rgb_vclk_to_mic0"; 74 power-domains = <&pd_disp>; 75 samsung,disp-syscon = <&syscon_disp>; 76 77 ports { 78 #address-cells = <1>; 79 #size-cells = <0>; 80 81 port@0 { 82 reg = <0>; 83 mic_to_decon: endpoint { 84 remote-endpoint = <&decon_to_mic>; 85 }; 86 }; 87 88 port@1 { 89 reg = <1>; 90 mic_to_dsi: endpoint { 91 remote-endpoint = <&dsi_to_mic>; 92 }; 93 }; 94 }; 95 }; 96
