1Exynos MIPI-DSIM Controller
2=========================
3
4Required properties:
5SOC specific:
6	compatible: should be "samsung,exynos-mipi-dsi"
7	reg: Base address of MIPI-DSIM IP.
8
9Board specific:
10	samsung,dsim-config-e-interface: interface to be used (RGB interface
11		for main display or CPU interface for main or sub display).
12	samsung,dsim-config-e-virtual-ch: virtual channel number that main
13		or sub display uses.
14	samsung,dsim-config-e-pixel-format: pixel stream format for main
15		or sub display.
16	samsung,dsim-config-e-burst-mode: selects Burst mode in Video mode.
17		in Non-burst mode, RGB data area is filled with RGB data and
18		NULL packets, according to input bandwidth of RGB interface.
19	samsung,dsim-config-e-no-data-lane: data lane count used by Master.
20	samsung,dsim-config-e-byte-clk: select byte clock source.
21		It must be DSIM_PLL_OUT_DIV8.
22		DSIM_EXT_CLK_DIV8 and DSIM_EXT_CLK_BYPASSS are not supported.
23	samsung,dsim-config-hfp: HFP disable mode.
24		If set, DSI master ignores HFP area in VIDEO mode.
25		In command mode, this variable is ignored.
26	samsung,dsim-config-p: P value for PMS setting.
27	samsung,dsim-config-m: M value for PMS setting.
28	samsung,dsim-config-s: S value for PMS setting.
29	samsung,dsim-config-pll-stable-time: the PLL Timer for stability
30		of the ganerated clock.
31	samsung,dsim-config-esc-clk: escape clock frequency for getting
32		the escape clock prescaler value.
33	samsung,dsim-config-stop-holding-cnt: the interval value between
34		transmitting read packet (or write "set_tear_on" command)
35		and BTA request. After transmitting read packet or write
36		"set_tear_on" command, BTA requests to D-PHY automatically.
37		This counter value specifies the interval between them.
38	samsung,dsim-config-bta-timeout: the timer for BTA. This register
39		specifies time out from BTA request to change the direction
40		with respect to Tx escape clock.
41	samsung,dsim-config-rx-timeout: the timer for LP Rx mode timeout.
42		this register specifies time out on how long RxValid deasserts,
43		after RxLpdt asserts with respect to Tx escape clock.
44		- RxValid specifies Rx data valid indicator.
45		- RxLpdt specifies an indicator that D-PHY is under RxLpdt mode
46		- RxValid and RxLpdt specifies signal from D-PHY.
47	samsung,dsim-device-name: name of the device.
48	samsung,dsim-device-id: unique device id.
49	samsung,dsim-device-bus_id: bus id for identifing connected bus
50		and this bus id should be same as id of mipi_dsim_device.
51
52Optional properties:
53	samsung,dsim-device-reverse-panel: reverse panel.
54
