+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>;

+Device-Tree bindings for Samsung SoC display controller (FIMD)
+
+FIMD (Fully Interactive Mobile Display) is the Display Controller for the
+Samsung 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 the following
+ "samsung,s3c2443-fimd"; /* for S3C24XX SoCs */
+ "samsung,s3c6400-fimd"; /* for S3C64XX SoCs */
+ "samsung,s5pv210-fimd"; /* for S5PV210 SoC */
+ "samsung,exynos3250-fimd"; /* for Exynos3250/3472 SoCs */
+ "samsung,exynos4210-fimd"; /* for Exynos4 SoCs */
+ "samsung,exynos5250-fimd"; /* for Exynos5250 SoCs */
+ "samsung,exynos5420-fimd"; /* for Exynos5420/5422/5800 SoCs */
+
+- reg: physical base address and length of the FIMD registers set.
+
+- interrupts: should contain a list of all FIMD IP block interrupts in the
+ order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
+ format depends on the interrupt controller used.
+
+- interrupt-names: should contain the interrupt names: "fifo", "vsync",
+ "lcd_sys", in the same order as they were listed in the interrupts
+ property.
+
+- pinctrl-0: pin control group to be used for this controller.
+
+- pinctrl-names: must contain a "default" entry.
+
+- 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 "sclk_fimd" and "fimd".
+
+Optional Properties:
+- power-domains: a phandle to FIMD power domain node.
+- samsung,invert-vden: video enable signal is inverted
+- samsung,invert-vclk: video clock signal is inverted
+- display-timings: timing settings for FIMD, as described in document [1].
+ Can be used in case timings cannot be provided otherwise
+ or to override timings provided by the panel.
+- samsung,sysreg: handle to syscon used to control the system registers
+- i80-if-timings: timing configuration for lcd i80 interface support.
+ - cs-setup: clock cycles for the active period of address signal is enabled
+ until chip select is enabled.
+ If not specified, the default value(0) will be used.
+ - wr-setup: clock cycles for the active period of CS signal is enabled until
+ write signal is enabled.
+ If not specified, the default value(0) will be used.
+ - wr-active: clock cycles for the active period of CS is enabled.
+ If not specified, the default value(1) will be used.
+ - wr-hold: clock cycles for the active period of CS is disabled until write
+ signal is disabled.
+ If not specified, the default value(0) will be used.
+
+ The parameters are defined as:
+
+ VCLK(internal) __|??????|_____|??????|_____|??????|_____|??????|_____|??
+ : : : : :
+ Address Output --:<XXXXXXXXXXX:XXXXXXXXXXXX:XXXXXXXXXXXX:XXXXXXXXXXXX:XX
+ | cs-setup+1 | : : :
+ |<---------->| : : :
+ Chip Select ???????????????|____________:____________:____________|??
+ | wr-setup+1 | | wr-hold+1 |
+ |<---------->| |<---------->|
+ Write Enable ????????????????????????????|____________|???????????????
+ | wr-active+1|
+ |<---------->|
+ Video Data ----------------------------<XXXXXXXXXXXXXXXXXXXXXXXXX>--
+
+The device node can contain 'port' child nodes according to the bindings defined
+in [2]. The following are properties specific to those nodes:
+- reg: (required) port index, can be:
+ 0 - for CAMIF0 input,
+ 1 - for CAMIF1 input,
+ 2 - for CAMIF2 input,
+ 3 - for parallel output,
+ 4 - for write-back interface
