- Device-Tree bindings for Samsung Exynos SoC mobile image compressor (MIC)
- MIC (mobile image compressor) resides between decon and mipi dsi. Mipi dsi is
- not capable to transfer high resoltuion frame data as decon can send. MIC
- solves this problem by compressing the frame data by 1/2 before it is
- transferred through mipi dsi. The compressed frame data must be uncompressed in
- the panel PCB.
- Required properties:
- - compatible: value should be "samsung,exynos5433-mic".
- - reg: physical base address and length of the MIC registers set and system
- register of mic.
- - 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_mic0", "sclk_rgb_vclk_to_mic0".
- - samsung,disp-syscon: the reference node for syscon for DISP block.
- - ports: contains a port which is connected to decon node and dsi node.
- address-cells and size-cells must 1 and 0, respectively.
- - port: contains an endpoint node which is connected to the endpoint in the
- decon node or dsi node. The reg value must be 0 and 1 respectively.
- Example:
- SoC specific DT entry:
- mic: mic@13930000 {
- compatible = "samsung,exynos5433-mic";
- reg = <0x13930000 0x48>;
- clocks = <&cmu_disp CLK_PCLK_MIC0>,
- <&cmu_disp CLK_SCLK_RGB_VCLK_TO_MIC0>;
- clock-names = "pclk_mic0", "sclk_rgb_vclk_to_mic0";
- samsung,disp-syscon = <&syscon_disp>;
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
- port@0 {
- reg = <0>;
- mic_to_decon: endpoint {
- remote-endpoint = <&decon_to_mic>;
- };
- };
- port@1 {
- reg = <1>;
- mic_to_dsi: endpoint {
- remote-endpoint = <&dsi_to_mic>;
- };
- };
- };
- };
