The driver is quite similar to existing ssd130x-i2c driver that is used by I2C controllers, but there is a difference in the protocol used by SSD130x depending on the transport used. The details are in patch #4 description. Patch #1 just makes the current ssd130x-i2c compatible strings in the DT binding to be deprecated, and add new ones that don't have an "fb-i2c". Patch #2 extends the DT binding with the properties needed to support SPI. Patch #3 adds the new compatible strings to the OF device ID table in the ssd130x-i2c DRM driver and deprecate the old ones. Patch #4 moves the device info for the different SSD130x variants from the ssd130x-i2c transport driver to the ssd130x core driver. Finally patch #5 adds the ssd130x-spi DRM driver for the OLED controllers that come with a 4-wire SPI interface, instead of an I2C interface. This is a v2 that addresses the issues pointed out in v1. Best regards, Javier Changes in v2: - Drop the -i2c suffixes from the compatible strings too (Geert Uytterhoeven). - Don't add compatible strings with an "-spi" suffix (Geert Uytterhoeven). - Drop ssd13x_variant_to_info() and just use the array index (Neil Armstrong). - Add Mark Brown's Acked-by tag to all patches.
