+Exynos MIPI-DSIM Controller
+=========================
+
+Required properties:
+SOC specific:
+ compatible: should be "samsung,exynos-mipi-dsi"
+ reg: Base address of MIPI-DSIM IP.
+
+Board specific:
+ samsung,dsim-config-e-interface: interface to be used (RGB interface
+ for main display or CPU interface for main or sub display).
+ samsung,dsim-config-e-virtual-ch: virtual channel number that main
+ or sub display uses.
+ samsung,dsim-config-e-pixel-format: pixel stream format for main
+ or sub display.
+ samsung,dsim-config-e-burst-mode: selects Burst mode in Video mode.
+ in Non-burst mode, RGB data area is filled with RGB data and
+ NULL packets, according to input bandwidth of RGB interface.
+ samsung,dsim-config-e-no-data-lane: data lane count used by Master.
+ samsung,dsim-config-e-byte-clk: select byte clock source.
+ It must be DSIM_PLL_OUT_DIV8.
+ DSIM_EXT_CLK_DIV8 and DSIM_EXT_CLK_BYPASSS are not supported.
+ samsung,dsim-config-hfp: HFP disable mode.
+ If set, DSI master ignores HFP area in VIDEO mode.
+ In command mode, this variable is ignored.
+ samsung,dsim-config-p: P value for PMS setting.
+ samsung,dsim-config-m: M value for PMS setting.
+ samsung,dsim-config-s: S value for PMS setting.
+ samsung,dsim-config-pll-stable-time: the PLL Timer for stability
+ of the ganerated clock.
+ samsung,dsim-config-esc-clk: escape clock frequency for getting
+ the escape clock prescaler value.
+ samsung,dsim-config-stop-holding-cnt: the interval value between
+ transmitting read packet (or write "set_tear_on" command)
+ and BTA request. After transmitting read packet or write
+ "set_tear_on" command, BTA requests to D-PHY automatically.
+ This counter value specifies the interval between them.
+ samsung,dsim-config-bta-timeout: the timer for BTA. This register
+ specifies time out from BTA request to change the direction
+ with respect to Tx escape clock.
+ samsung,dsim-config-rx-timeout: the timer for LP Rx mode timeout.
+ this register specifies time out on how long RxValid deasserts,
+ after RxLpdt asserts with respect to Tx escape clock.
+ - RxValid specifies Rx data valid indicator.
+ - RxLpdt specifies an indicator that D-PHY is under RxLpdt mode
+ - RxValid and RxLpdt specifies signal from D-PHY.
+ samsung,dsim-device-name: name of the device.
+ samsung,dsim-device-id: unique device id.
+ samsung,dsim-device-bus_id: bus id for identifing connected bus
+ and this bus id should be same as id of mipi_dsim_device.
+
+Optional properties:
+ samsung,dsim-device-reverse-panel: reverse panel.
+
+Example:
+ mipidsi@11c80000 {
+ compatible = "samsung,exynos-mipi-dsi";
