- - hsync-active: hsync pulse is active low/high/ignored

42

43
- - interlaced (bool): boolean to enable interlaced mode
44
- - doublescan (bool): boolean to enable doublescan mode
45
- - doubleclk (bool): boolean to enable doubleclock mode
46

47
-All the optional properties that are not bool follow the following logic:
48
-    <1>: high active
49
-    <0>: low active
50
-    omitted: not used on hardware
51

52
-There are different ways of describing the capabilities of a display. The
53
-devicetree representation corresponds to the one commonly found in datasheets
54
-for displays. If a display supports multiple signal timings, the native-mode
55
-can be specified.

-Note: In addition to being used as subnode(s) of display-timings, the timing
84
-      subnode may also be used on its own. This is appropriate if only one mode
85
-      need be conveyed. In this case, the node should be named 'panel-timing'.
86

87

88
-Example:
89
-
90
-	display-timings {
91
-		native-mode = <&timing0>;
92
-		timing0: 1080p24 {
93
-			/* 1920x1080p24 */
94
-			clock-frequency = <52000000>;
95
-			hactive = <1920>;
96
-			vactive = <1080>;
97
-			hfront-porch = <25>;
98
-			hback-porch = <25>;
99
-			hsync-len = <25>;
100
-			vback-porch = <2>;
101
-			vfront-porch = <2>;
102
-			vsync-len = <2>;
103
-			hsync-active = <1>;
104
-		};
105
-	};
106
-
107
-Every required property also supports the use of ranges, so the commonly used
108
-datasheet description with minimum, typical and maximum values can be used.

-Example:
111
-
112
-	timing1: timing {
113
-		/* 1920x1080p24 */
114
-		clock-frequency = <148500000>;
115
-		hactive = <1920>;
116
-		vactive = <1080>;
117
-		hsync-len = <0 44 60>;
118
-		hfront-porch = <80 88 95>;
119
-		hback-porch = <100 148 160>;
120
-		vfront-porch = <0 4 6>;
121
-		vback-porch = <0 36 50>;
122
-		vsync-len = <0 5 6>;
