You need to break this into several patches and several files.

You can not put everything in rockchip_canfd-core.c. Create a
rockchip_rk3568.c in which you will move all the already existing
rk3568 specific functions. Then, in another patch, create a
rockchip_rk3576.c that will contain all the new code. Also adjust the
headers accordingly.

I think the first patch modifying driver code should be to add the
callbacks to rockchip_canfd-core.c and move the rk3568 code to it. The
second patch to add the rk3576 without DMA and then add DMA mode. Maybe
even split more. Have a look at the series where I added the original
driver for an idea how to add the support incremental.

Marc
