[v4,00/11] Add support for RZ/G3E CANFD

Message

Biju Das March 6, 2025, 12:42 p.m. UTC

The CAN-FD module on RZ/G3E is very similar to the one on both R-Car V4H
and RZ/G2L, but differs in some hardware parameters:
 * No external clock, but instead has ram clock.
 * Support up to 6 channels.
 * 20 interrupts.

This patch series depend upon [1]
[1] https://lore.kernel.org/all/[e-mail]/

v3->v4:
 * Added Rb tag from Rob for patch#2.
 * Added prefix RCANFD_* to enum rcar_canfd_reg_offset_id.
 * Added prefix RCANFD_* to enum rcar_canfd_mask_id.
 * Added prefix RCANFD_* to enum rcar_canfd_shift_id.
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.
