        Hi all,

This patch series contains fixes and improvements for the XRGB888 to
monochrome conversion in the DRM core, and for its users.

This has been tested on an Adafruit FeatherWing 128x32 OLED, connected
to an OrangeCrab ECP5 FPGA board running a 64 MHz VexRiscv RISC-V
softcore, using a text console with 4x6, 7x14 and 8x8 fonts.

Thanks!

Geert Uytterhoeven (5):
  drm/format-helper: Rename drm_fb_xrgb8888_to_mono_reversed()
  drm/format-helper: Fix XRGB888 to monochrome conversion
  drm/ssd130x: Fix rectangle updates
  drm/ssd130x: Reduce temporary buffer sizes
  drm/repaper: Reduce temporary buffer size in repaper_fb_dirty()

when I'm talking to journalists I just say "programmer" or something like that.
