that is just a shift register which converts the serial data stream into 18bit parallel. To my best knowleadge this has to be made because of a bug in the ILI9486 SPI interface...
The dtoverlay = piscreen,drm will use an overlay that assumes the hardware has an spi to dpi preprocessor sitting on it.
I do not know why the linux repo allowed the kernel module behind the piscreen overlay to be pushed as an ili9486 driver as it does not talk to the ili9486 chip directly. ..
hmm, can you show me why it's not supporting 18bit (rgb666)?..
The reason the mipi-dbi-spi driver doesn't work so well with the ili9486 and ili9488 is because the mipi code does not support rgb666. ..
