[PATCH 2/3] can: rockchip: add RK3588 CAN-FD support

Hi Marc,

thanks for the feedback.

Understood. I will keep CAN-FD disabled for RK3588 in v2.

I will also try to investigate whether the failing BRS/data-phase setup
can be fixed. If I can find a proper fix, I will send it as a follow-up
patch instead of mixing it into this v2 series.

Yes. I will update the RK3588 quirk description and add the reproduce
steps for the BRS/data bitrate issue.

> Please keep it disabled for now.

I will keep RKCANFD_QUIRK_CANFD_BROKEN enabled for RK3588 in v2, so
CAN-FD stays disabled for now.

Thanks,
