* Solomon SSD1307 Framebuffer Driver
Required properties:
- compatible: Should be "solomon,<chip>fb-<bus>". The only supported bus for
now is i2c, and the supported chips are ssd1306 and ssd1307.
- reg: Should contain address of the controller on the I2C bus. Most likely
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?
