====================
pull-request: can-next 2025-05-22

this is a pull request of 22 patches for net-next/main.

The series by Biju Das contains 19 patches and adds RZ/G3E CANFD
support to the rcar_canfd driver.

The patch by Vincent Mailhol adds a struct data_bittiming_params to
group FD parameters as a preparation patch for CAN-XL support.

Felix Maurer's patch imports tst-filter from can-tests into the kernel
self tests and Vincent Mailhol adds support for physical CAN
interfaces.
