Upstream Linux (plus Collabora's in-flight patches) has support for the camera interface on RK3588, but not RK3576. They differ primarily in the number of cores and minor GRF layout, so the RK3588 code should be relatively easy to port to RK3576.
Flipper One uses lanes 0 and 1 from the MIPI DPHY CSI3 RX controller for its camera interface. That's similar to ArmSoM Sige5 CS1_MIPI port or FriendlyElec NanoPi M5 MIPI-CSI1 port, but at half the bandwidth. If the Sige5/NanoPi M5 interface can be made to work, then Flipper One should work too with the same code.
