[PATCH v2 0/2] can: flexcan: add transceiver capabilities
From: Dimitri Fedrau via B4 Relay
Date: Thu Feb 20 2025 - 03:24:27 EST
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.

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
