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
