36 The label property specifies a symbolic name for the panel as a
37 string suitable for use by humans. It typically contains a name inscribed
43 non-descriptive information. For instance an LCD panel in a system that
44 contains a single panel shall not be labelled "LCD" if that name is not
45 inscribed on the system or used in a descriptive fashion in system

63 panel-timing:
65 Most display panels are restricted to a single resolution and
66 require specific display timings. The panel-timing subnode expresses those

70 display-timings:
72 Some display panels support several resolutions with different timings.
73 The display-timings bindings supports specifying several timings and

81 ddc-i2c-bus:
84 Some panels expose EDID information through an I2C-compatible
85 bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a

98 If Hot Plug Detect (HPD) is connected to a GPIO in the system rather
99 than a dedicated HPD pin the pin can be specified here.
103 # Many display panels can be controlled through pins driven by GPIOs. The nature
104 # and timing of those control signals are device-specific and left for panel

111 Specifier for a GPIO connected to the panel enable control signal. The

121 reset-gpios:
124 Specifier for a GPIO connected to the panel reset control signal.

137 power-supply:
139 Display panels require power to be supplied. While several panels need
140 more than one power supply with panel-specific constraints governing the
141 order and timings of the power supplies, in many cases a single power
142 supply is sufficient, either because the panel has a single power rail, or
144 the power-supply property specifies the supply powering the panel as a
145 phandle to a regulator.
149 # Most display panels include a backlight. Some of them also include a backlight
150 # controller exposed through a control bus such as I2C or DSI. Others expose
