-* 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 ssd1305, 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?
- - solomon,segment-no-remap: Display needs normal (non-inverted) data column
- to segment mapping
- - solomon,com-seq: Display uses sequential COM pin configuration
- - solomon,com-lrremap: Display uses left-right COM pin remap
- - solomon,com-invdir: Display uses inverted COM pin scan direction
- - solomon,com-offset: Number of the COM pin wired to the first display line
- - solomon,prechargep1: Length of deselect period (phase 1) in clock cycles.
- - solomon,prechargep2: Length of precharge period (phase 2) in clock cycles.
- This needs to be the higher, the higher the capacitance
- of the OLED's pixels is
