Subject: [PATCH v2 0/3] R-Car CANFD fixes
Date: Tue, 25 Oct 2022 16:56:54 +0100 [thread overview]
Message-ID: <20221025155657.1426948-1-biju.das.jz@bp.renesas.com> (raw)
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 storm 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.
v1->v2:
* Added check for irq active and enabled before handling the irq on a
particular channel.
