      1Exynos MIPI DSI Master
      2
      3Required properties:
      4  - compatible: value should be one of the following
      5		"samsung,exynos3250-mipi-dsi" /* for Exynos3250/3472 SoCs */
      6		"samsung,exynos4210-mipi-dsi" /* for Exynos4 SoCs */
      7		"samsung,exynos5410-mipi-dsi" /* for Exynos5410/5420/5440 SoCs */
      8		"samsung,exynos5422-mipi-dsi" /* for Exynos5422/5800 SoCs */
      9		"samsung,exynos5433-mipi-dsi" /* for Exynos5433 SoCs */
     10  - reg: physical base address and length of the registers set for the device
     11  - interrupts: should contain DSI interrupt
     12  - clocks: list of clock specifiers, must contain an entry for each required
     13    entry in clock-names
     14  - clock-names: should include "bus_clk"and "sclk_mipi" entries
     15		 the use of "pll_clk" is deprecated
     16  - phys: list of phy specifiers, must contain an entry for each required
     17    entry in phy-names
     18  - phy-names: should include "dsim" entry
     19  - vddcore-supply: MIPI DSIM Core voltage supply (e.g. 1.1V)
     20  - vddio-supply: MIPI DSIM I/O and PLL voltage supply (e.g. 1.8V)
     21  - samsung,pll-clock-frequency: specifies frequency of the oscillator clock
     22  - #address-cells, #size-cells: should be set respectively to <1> and <0>
     23    according to DSI host bindings (see MIPI DSI bindings [1])
     24  - samsung,burst-clock-frequency: specifies DSI frequency in high-speed burst
     25    mode
     26  - samsung,esc-clock-frequency: specifies DSI frequency in escape mode
     27
     28Optional properties:
     29  - power-domains: a phandle to DSIM power domain node
     30
     31Child nodes:
     32  Should contain DSI peripheral nodes (see MIPI DSI bindings [1]).
     33
     34Video interfaces:
     35  Device node can contain following video interface port nodes according to [2]:
     36  0: RGB input,
     37  1: DSI output
