Interfacing (DSI, CSI, I2C, etc.) • Re: Interfacing a 8-bit Serial RGB Display

Thank you, I will certainly look into this. In order to enable the colors in turn I guess I will have to edit the driver itself?
If the display-width is 3 times larger, how will this affect the image scaling on the display?
What driver are you looking at? Unless the panel needs further configuration, then panel-dpi and the vc4-kms-dpi-generic overlay probably allow enough control. Just triple the clock and all horizontal timing numbers.
It'll have a very slight effect on scaling, but for 320x240 I wouldn't expect it to be too significant.
I have also looked at using a 3 x clock multiplier, a counter (3 bit) and 8 x 3:1 demux/muxes. This way I could treat the display as a normal RGB display and just have a PCB in between that does the conversion. Does this sound plausible as well?
That would be plausible. Clock multipliers (aka PLLs) are more complex to get right than frigging the software though.
