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.
