Here's a driver I have been working on:

drm/panel: Add MIPI DBI compatible SPI driver
https://lore.kernel.org/dri-devel/20220125175700.37408-1-noralf@tronnes.org/

It should replace the SPI part of these fbtft drivers if accepted:

$ grep -lr MIPI_DCS drivers/staging/fbtft/ | grep -v "-" | uniq | sort
drivers/staging/fbtft/fb_hx8340bn.c
drivers/staging/fbtft/fb_hx8353d.c
drivers/staging/fbtft/fb_hx8357d.c
drivers/staging/fbtft/fb_ili9163.c
drivers/staging/fbtft/fb_ili9340.c
drivers/staging/fbtft/fb_ili9341.c
drivers/staging/fbtft/fb_ili9481.c
drivers/staging/fbtft/fb_ili9486.c
drivers/staging/fbtft/fb_s6d02a1.c
drivers/staging/fbtft/fb_st7735r.c
drivers/staging/fbtft/fb_st7789v.c
drivers/staging/fbtft/fb_tinylcd.c

There's no support for the parallel interface on these controllers in
drm. Support could be added to drivers/gpu/drm/drm_mipi_dbi.c.

Here's a status report I wrote 2 years ago:

fbtft: 5 years in staging
https://lore.kernel.org/dri-devel/a6cef26c-0f4b-47f0-d249-71f53891526b@tronnes.org/
