* 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, ssd1307 and
ssd1309.
- 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
