Subject: [PATCH 0/6] R-Can CAN FD driver enhancements

The CAN FD IP found on RZ/G2L SoC has some HW features different to that
of R-Car. For example, it has multiple resets and multiple IRQs for global
and channel interrupts. Also, it does not have ECC error flag registers
and clk post divider present on R-Car. Similarly, R-Car V3U has 8 channels
whereas other SoCs has only 2 channels.

Currently all the differences are taken by comparing chip_id enum.
This patch series aims to replace chip_id with struct rcar_canfd_hw_info
to take care of the HW feature differences and driver data present
on both IPs.

The changes are trivial and tested on RZ/G2L SMARC EVK.

This patch series depend upon[1]

Biju Das (6):
  can: rcar_canfd: rcar_canfd_probe: Add struct rcar_canfd_hw_info to
    driver data
  can: rcar_canfd: Add max_channels to struct rcar_canfd_hw_info
  can: rcar_canfd: Add multi_global_irqs to struct rcar_canfd_hw_info
  can: rcar_canfd: Add clk_postdiv to struct rcar_canfd_hw_info
  can: rcar_canfd: Add multi_channel_irqs to struct rcar_canfd_hw_info
  can: rcar_canfd: Add has_gerfl_eef to struct rcar_canfd_hw_info
