Use CircuitCo MiniDisplay cape as framebuffer device?

Hi, I have the 128x128 LCD MiniDisplay Cape from CircuitCo:

I’m curious to know if anyone has this working as a framebuffer device. The wiki article links to Matt Porter’s talk:
http://elinux.org/images/1/19/Passing_Time_With_SPI_Framebuffer_Driver.pdf

That PDF contains a link for the ST7735FB driver to:
https://github.com/ohporter/linux-am33x/tree/st7735fb

Anyone had success with this?

Thanks,
Drew
