Dssd1307fb.txt4 - compatible: Should be "solomon,<chip>fb-<bus>". The only supported bus for
7 - reg: Should contain address of the controller on the I2C bus. Most likely
9 - pwm: Should contain the pwm to use according to the OF device tree PWM
11 - solomon,height: Height in pixel of the screen driven by the controller
12 - solomon,width: Width in pixel of the screen driven by the controller
13 - solomon,page-offset: Offset of pages (band of 8 pixels) that the screen is
17 - reset-gpios: The GPIO used to reset the OLED display, if available. See
19 - vbat-supply: The supply for VBAT
20 - solomon,segment-no-remap: Display needs normal (non-inverted) data column
22 - solomon,col-offset: Offset of columns (COL/SEG) that the screen is mapped to.
