| * 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. | |
| - 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-gpios: The GPIO used to reset the OLED display, if available. See | |
| Documentation/devicetree/bindings/gpio/gpio.txt for details. | |
| - vbat-supply: The supply for VBAT | |
| - 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 | |
