Currently the flexcan driver does only support adding PHYs by using the "old" regulator bindings. Add support for CAN transceivers as a PHY. Add the capability to ensure that the PHY is in operational state when the link is set to an "up" state. Signed-off-by: Dimitri Fedrau <dimitri.fedrau@xxxxxxxxxxxx> --- Changes in v2: - Rename variable xceiver to transceiver in struct flexcan_priv and in flexcan_probe - Set priv->can.bitrate_max if transceiver is found - Fix commit messages which claim that transceivers are not supported - Do not print error on EPROBE_DEFER after calling devm_phy_optional_get in flexcan_probe - Link to v1: https://lore.kernel.org/r/20250211-flexcan-add-transceiver-caps-v1-0-c6abb7817b0f@xxxxxxxxxxxx --- Dimitri Fedrau (2): dt-bindings: can: fsl,flexcan: add transceiver capabilities can: flexcan: add transceiver capabilities .../devicetree/bindings/net/can/fsl,flexcan.yaml | 3 +++ drivers/net/can/flexcan/flexcan-core.c | 30 +++++++++++++++++----- drivers/net/can/flexcan/flexcan.h | 1 + 3 files changed, 28 insertions(+), 6 deletions(-) --- base-commit: 6a24171b9625471abfc90c7b28c4b45bee64b3a4 change-id: 20241209-flexcan-add-transceiver-caps-7cff9400c926 Best regards, -- Dimitri Fedrau <dimitri.fedrau@xxxxxxxxxxxx>
