Hello,
This series adds a ssd130x-spi driver that provides a 4-wire SPI transport support for SSD130x OLED controllers that can be accessed over a SPI bus.
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 v5 that addresses the issues pointed out in v4.
Pushed this series to drm-misc-next after adding Rob's Reviewed-by tags to patch 1/5 and 2/5, since I missed that in v5. Thanks all!
