The commit 5cff263606a1 ("can: rcar_canfd: Fix controller mode setting") has aligned with the flow mentioned in the hardware manual for all SoCs except R-Car Gen3 and RZ/G2L SoCs. On R-Car Gen4 and RZ/G3E SoCs, due to the wrong logic in the commit[1] sets the default mode to FD-Only mode instead of CAN-FD mode.
This patch sets the CAN-FD mode as the default for all SoCs by dropping the rcar_canfd_set_mode() as some SoC requires mode setting in global reset mode, and the rest of the SoCs in channel reset mode and update the rcar_canfd_reset_controller() to take care of these constraints. Moreover, the RZ/G3E and R-Car Gen4 SoCs support 3 modes compared to 2 modes on the R-Car Gen3. Use inverted logic in rcar_canfd_reset_controller() to simplify the code later to support FD-only mode.
Applied to linux-can
