If you're fine with going low-level, there's tentative [1] which can apply an
arbitrary KMS state. See for instance [2] for basic

Thanks for your series!
I'll give it a try on an Adafruit

I don't think the color matters that much. "Red" was picked just because it was
an arbitrary color,

This driver only advertises XRGB in ssd1307_formats. It would be nice to
expose R8 as well so that user-space can directly produce suitable buffers.
It would also be nice to have some kind of preferred format, so that user-space
knows R8 is preferred over XRGB.
This patch series adds a DRM driver for the Solomon OLED SSD1305, SSD1306,
SSD1307 and SSD1309 displays. It is a port of the ssd1307fb fbdev driver.
Using the DRM fb emulation, all the tests from Geert Uytterhoeven's fbtest
