[PATCH] can: flexcan: Convert the driver to DT-only

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The flexcan driver runs only on DT platforms, so simplify the
code by using of_device_get_match_data() to retrieve the
driver data and also by removing the unused id_table.
