====================
pull-request: can-next 2023-04-04-2

The first patch is by Oliver Hartkopp and makes the maximum pdu size
of the CAN ISOTP protocol configurable.

The following 5 patches are by Dario Binacchi and add support for the
bxCAN controller by ST.

Geert Uytterhoeven's patch for the rcar_canfd driver fixes a sparse
warning.

Peng Fan's patch adds an optional power-domains property to the
flexcan device tree binding.

Frank Jungclaus adds support for CAN_CTRLMODE_BERR_REPORTING to the
esd_usb driver.

The last patch is by Oliver Hartkopp and converts the USB IDs of the
kvaser_usb driver to hexadecimal values.
