Subject: [PATCH 0/3] R-Car CANFD fixes

This patch series fixes the below issues in R-Car CAN FD driver.

 1) Race condition in CAN driver under heavy CAN load condition
    with both channels enabled results in IRQ stom on global fifo
    receive irq line.
 2) Add channel specific tx interrupts handling for RZ/G2L SoC as it has
    separate IRQ lines for each tx.
 3) Remove unnecessary SoC specific checks in probe.

Biju Das (3):
  can: rcar_canfd: Fix IRQ storm on global fifo receive
  can: rcar_canfd: Fix channel specific IRQ handling for RZ/G2L
  can: rcar_canfd: Use devm_reset_control_get_optional_exclusive
