The patch adds DT bindings for Exynos DSI Master. DSIM follows rules for DSI bus host bindings [1]. Properties describes its resources: memory, interrupt, clocks, phy, regulators and frequencies of clocks.
Signed-off-by: Andrzej Hajda a.hajda@samsung.com
v2
- added burst and esc clock frequency properties
- add samsung prefix to all frequency props

+Required properties:
- compatible: "samsung,exynos4210-mipi-dsi"
- 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
- samsung,burst-clock-frequency: specifies DSI frequency in high-speed burst
- mode
- samsung,esc-clock-frequency: specifies DSI frequency in escape mode
- #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 DSI bindings [1])

Isn't a property indicating cpu or video mode needed for the future even though now DSI driver doesn't support CPU interface yet? Which mode is used would depend on machine.
