Subject[PATCH v2 2/5] dt-bindings: display: ssd1307fb: Extend schema for SPI controllers
Date
The Solomon SSD130x OLED displays can either have an I2C or SPI interface,
add to the schema the properties and examples for OLED devices under SPI.

Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

Changes in v2:
- Don't add compatible strings with an "-spi" suffix (Geert Uytterhoeven).
