73   ddc-i2c-bus:
76       Some panels expose EDID information through an I2C-compatible

100   enable-gpios:
103       Specifier for a GPIO connected to the panel enable control signal. The
104       enable signal is active high and enables operation of the panel. This
105       property can also be used for panels implementing an active low power down
106       signal, which is a negated version of the enable signal. Active low enable
107       signals (or active high power down signals) can be supported by inverting
108       the GPIO specifier polarity flag.
113   reset-gpios:
116       Specifier for a GPIO connected to the panel reset control signal.
117       The reset signal is active low and resets the panel internal logic
118       while active. Active high reset signals can be supported by inverting the
119       GPIO specifier polarity flag.
121   te-gpios:
124       GPIO spec for the tearing effect synchronization signal.
125       The tearing effect signal is active high. Active low signals can be
126       supported by inverting the GPIO specifier polarity flag.
