gpio driver porting from an r-pi3b

[gene83]

I've an spi driver that runs on a pi3, writing (and reading from) 32 bit packets at nominally 42 megabaud, to a mesa 7i90HD cnc interfacing card, and reading back at 25 megabaud. But its full of code that checks to make sure its running on a pi. It also has an include file that describes the bcm2835 for all its offsets etc. I can excise the pi checks, but what else do I need to do to make it run on the rock64?  The spi port used is nominally the SPI1 address in the pi scheme of things.


Thanks & Cheers
