Prefs
   1* Solomon SSD1307 Framebuffer Driver
   2
   3Required properties:
   4  - compatible: Should be "solomon,<chip>fb-<bus>". The only supported bus for
   5    now is i2c, and the supported chips are ssd1306 and ssd1307.
   6  - reg: Should contain address of the controller on the I2C bus. Most likely
   7         0x3c or 0x3d
   8  - pwm: Should contain the pwm to use according to the OF device tree PWM
   9         specification [0]. Only required for the ssd1307.
  10  - reset-gpios: Should contain the GPIO used to reset the OLED display
  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
  14    mapped to.
