This patch series depend upon [1] [1] https://lore.kernel.org/all/20250220094516.126598-1-biju.das.jz@bp.renesas.com/ v2->v3: * Collected tags. * Dropped reg_gen4() and is_gen4() by adding mask_table, shift_table, regs, ch_interface_mode and shared_can_reg variables to struct rcar_canfd_hw_info. v1->v2: * Split the series with fixes patch separately. * Added patch for Simplify rcar_canfd_probe() using of_get_available_child_by_name() as dependency patch hit on can-next. * Added Rb tag from Vincent Mailhol. * Dropped redundant comment from commit description for patch#3.
