phy: phy-can-transceiver: Drop unused include

2026-05-14T15:32:21+00:00

This file does not use the symbols from the legacy header, so let's drop it. Reviewed-by: Josua Mayer Signed-off-by: Andy Shevchenko Link: https://patch.msgid.link/20260513220336.369628-7-andriy.shevchenko@linux.intel.com Signed-off-by: Vinod Koul

phy: phy-can-transceiver: Decouple assignment and definition in probe

2026-05-14T15:32:21+00:00

The code like int foo = X; ... if (bar) foo = Y; is prone to subtle mistakes and hence harder to maintain as the foo value may be changed inadvertently while code in '...' grown in lines. On top it's harder to navigate to understand the possible values of foo when branch is not taken (requires to look somewhere else in the code, far from the piece at hand). Besides that in case of taken branch the foo will be rewritten, which is not a problem per se, just an unneeded operation. Decouple assignment and definition to use if-else to address the inconveniences described above.

phy: phy-can-transceiver: Don't check for specific errors when parsing properties

2026-05-14T15:32:21+00:00

Instead of checking for the specific error codes (that can be considered a layering violation to some extent) check for the property existence first and then either parse it, or apply a default value. With that, return an error when parsing of the existing property fails.

phy: phy-can-transceiver: Move OF ID table closer to their user

2026-05-14T15:32:21+00:00

There is no code that uses ID table directly, except the struct device_driver at the end of the file. Hence, move table closer to its user. It's always possible to access them via a pointer.

phy: phy-can-transceiver: use device_get_match_data()

2026-05-14T15:32:21+00:00

Use the generic firmware node interface for retrieving device match data instead of the OF-specific one. While at it, drop unneeded argument to devm_phy_create() which extracts device node from the given device by default.

phy: phy-can-transceiver: Check driver match and driver data against NULL

2026-05-14T15:32:21+00:00

Every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override() so platform drivers that rely on the existence of a device's driver data need to verify its presence. Accordingly, add requisite match and driver data checks against NULL to the driver where they are missing.

Multiplexer subsystem has now added helpers for getting managed optional mux-state. Switch to the new devm_mux_state_get_optional helper. This change is only compile-tested.

2025-11-12T14:41:16+00:00

Support TJA105{1,7} which are a single channel high-speed CAN transceiver with silent mode supported. phy mode is not implemented as of now. silent settings are kept in phy_power_on and phy_power_off. After phy mode is supported, the silent settings could be moved to phy_set_mode.
