[PATCH net-next 0/47] pull-request: can-next 2023-02-06

[Marc Kleine-Budde <mkl@pengutronix.de>]

Hello Jakub, hello David,

this is a pull request of 47 patches for net-next/master.

The first two patch is by Oliver Hartkopp. One adds missing error
checking to the CAN_GW protocol, the other adds a missing CAN address
family check to the CAN ISO TP protocol.

Thomas Kopp contributes a performance optimization to the mcp251xfd
driver.

The next 11 patches are by Geert Uytterhoeven and add support for
R-Car V4H systems to the rcar_canfd driver.

Stephane Grosjean and Lukas Magel contribute 8 patches to the peak_usb
driver, which add support for configurable CAN channel ID.

The last 17 patches are by me and target the CAN bit timing
configuration. The bit timing is cleaned up, error messages are
improved and forwarded to user space via NL_SET_ERR_MSG_FMT() instead
of netdev_err(), and the SJW handling is updated, including the
definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

regards,
Marc
