@ -8,14 +8,15 @@ Required properties:
0x3c or 0x3d
- pwm: Should contain the pwm to use according to the OF device tree PWM
specification [0]. Only required for the ssd1307.
- reset-gpios: Should contain the GPIO used to reset the OLED display
- solomon,height: Height in pixel of the screen driven by the controller
- solomon,width: Width in pixel of the screen driven by the controller
- solomon,page-offset: Offset of pages (band of 8 pixels) that the screen is
mapped to.
Optional properties:
- reset-active-low: Is the reset gpio is active on physical low?
- reset-gpios: The GPIO used to reset the OLED display, if available. See
Documentation/devicetree/bindings/gpio/gpio.txt for details.
- vbat-supply: The supply for VBAT
- solomon,segment-no-remap: Display needs normal (non-inverted) data column
to segment mapping
- solomon,com-seq: Display uses sequential COM pin configuration
