1 * Solomon SSD1307 Framebuffer Driver
4 - compatible: Should be "solomon,<chip>fb-<bus>". The only supported bus for
5 now is i2c, and the supported chips are ssd1305, ssd1306, ssd1307 and
7 - reg: Should contain address of the controller on the I2C bus. Most likely
9 - pwm: Should contain the pwm to use according to the OF device tree PWM
10 specification [0]. Only required for the ssd1307.
11 - reset-gpios: Should contain the GPIO used to reset the OLED display
12 - solomon,height: Height in pixel of the screen driven by the controller
13 - solomon,width: Width in pixel of the screen driven by the controller
14 - solomon,page-offset: Offset of pages (band of 8 pixels) that the screen is
18 - reset-active-low: Is the reset gpio is active on physical low?
19 - solomon,segment-no-remap: Display needs normal (non-inverted) data column
21 - solomon,com-seq: Display uses sequential COM pin configuration
22 - solomon,com-lrremap: Display uses left-right COM pin remap
23 - solomon,com-invdir: Display uses inverted COM pin scan direction
24 - solomon,com-offset: Number of the COM pin wired to the first display line
25 - solomon,prechargep1: Length of deselect period (phase 1) in clock cycles.
26 - solomon,prechargep2: Length of precharge period (phase 2) in clock cycles.
27 This needs to be the higher, the higher the capacitance
28 of the OLED's pixels is
