- Exynos MIPI DSI Master
- Required properties:
- - compatible: value should be one of the following
- "samsung,exynos3250-mipi-dsi" /* for Exynos3250/3472 SoCs */
- "samsung,exynos4210-mipi-dsi" /* for Exynos4 SoCs */
- "samsung,exynos5410-mipi-dsi" /* for Exynos5410/5420/5440 SoCs */
- - reg: physical base address and length of the registers set for the device
- - interrupts: should contain DSI interrupt
- - clocks: list of clock specifiers, must contain an entry for each required
- entry in clock-names
- - clock-names: should include "bus_clk"and "pll_clk" entries
- - phys: list of phy specifiers, must contain an entry for each required
- entry in phy-names
- - phy-names: should include "dsim" entry
- - vddcore-supply: MIPI DSIM Core voltage supply (e.g. 1.1V)
- - vddio-supply: MIPI DSIM I/O and PLL voltage supply (e.g. 1.8V)
- - samsung,pll-clock-frequency: specifies frequency of the "pll_clk" clock
- - #address-cells, #size-cells: should be set respectively to <1> and <0>
- according to DSI host bindings (see MIPI DSI bindings [1])
- Optional properties:
- - samsung,power-domain: a phandle to DSIM power domain node
- Child nodes:
- Should contain DSI peripheral nodes (see MIPI DSI bindings [1]).
- Video interfaces:
- Device node can contain video interface port nodes according to [2].
- The following are properties specific to those nodes:
- port node:
- - reg: (required) can be 0 for input RGB/I80 port or 1 for DSI port;
- endpoint node of DSI port (reg = 1):
- - samsung,burst-clock-frequency: specifies DSI frequency in high-speed burst
- mode
- - samsung,esc-clock-frequency: specifies DSI frequency in escape mode

- ...
- port {
- panel_ep: endpoint {
- remote-endpoint = <&dsi_ep>;
- };
- };
- };
- ports {
- #address-cells = <1>;

- };
- };
- };
- };
