Searching for an overlay/howto for GPIO SPI LCD like Waveshare 3.5 inch (Linux)

Hi,

has anybody made a Waveshare 3.5 inch GPIO LCD or clone (SPI) work on a Rock 5A or B? Or any other GPIO Raspberry Pi display from 2.8" to 3.5".

If yes, which overlay have you used and which version of the display?

Many thanks in advanced
Henrik
