====================
pull-request: can-next 2021-04-13

this is a pull request of 14 patches for net-next/master.

The first patch is by Yoshihiro Shimoda and updates the DT bindings
for the rcar_can driver.

Vincent Mailhol contributes 3 patches that add support for several
ETAS USB CAN adapters.

The final 10 patches are by me and clean up the peak_usb CAN driver.
