[PATCH net-next 0/29] pull-request: can-next 2022-10-26

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

Hello Jakub, hello David,

this is a pull request of 29 patches for net-next/master.

The first patch is by Daniel S. Trevitz and adds documentation for
switchable termination resistors.

Zhang Changzhong's patch fixes a debug output in the j13939 stack.

Oliver Hartkopp finally removes the pch_can driver, which is
superseded by the generic c_can driver.

Gustavo A. R. Silva replaces a zero-length array with
DECLARE_FLEX_ARRAY() in the ucan driver.

Kees Cook's patch removes a no longer needed silencing of
"-Warray-bounds" warnings for the kvaser_usb driver.

The next 2 patches target the m_can driver. The first is by me cleans
up the LEC error handling, the second is by Vivek Yadav and extends
the LEC error handling to the data phase of CAN-FD frames.

The next 9 patches all target the gs_usb driver. The first 5 patches
are by me and improve the Kconfig prompt and help text, set
netdev->dev_id to distinguish multi CAN channel devices, allow
loopback and listen only at the same time, and clean up the
gs_can_open() function a bit. The remaining 4 patches are by Jeroen
Hofstee and add support for 2 new features: Bus Error Reporting and
Get State.

Jimmy Assarsson and Anssi Hannula contribute 10 patches for the
kvaser_usb driver. They first add Listen Only and Bus Error Reporting
support, handle CMD_ERROR_EVENT errors, improve CAN state handling,
restart events, and configuration of the bit timing parameters.

Another patch by me which fixes the indention in the m_can driver.

A patch by Dongliang Mu cleans up the ucan_disconnect() function in
the ucan driver.

The last patch by Biju Das is for the rcan_canfd driver and cleans up
the reset handling.

regards,
Marc
