This adds a DRM driver for SSD1305, SSD1306, SSD1307 and SSD1309 Solomon OLED display controllers.
It's only the core part of the driver and a bus specific driver is needed for each transport interface supported by the display controllers.

Thanks for your patch, which is now commit a61732e808672cfa ("drm: Add driver for Solomon SSD130x OLED displays") in drm/drm-next
Sorry for the delay, but finally I gave it a try on my Adafruit FeatherWing 128x32 OLED. Some of the weird issues (cursor disappears after printing some text, more text also doesn't appear until I clear the display) are still there. Unfortunately a regression was introduced since your v3: printed text is mirrored upside-down. I.e. "E" is rendered correctly, but "L" turns into "Γ" (Greek Gamma). I suspect something went wrong with the display initialization sequence.
