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

Hello Jakub, hello David,

this is a pull request of 39 patches for net-next/master.

The first two patches update the MAINTAINERS file. One is by me and
removes Dan Murphy from the from m_can and tcan4x5x. The other one is
by Pankaj Sharma and updates the maintainership of the m-can mmio
driver.

The next three patches are by me and update the CAN echo skb handling.

Vincent Mailhol provides 5 patches where Transmitter Delay
Compensation is added CAN bittiming calculation is cleaned up.

The next patch is by me and adds a missing HAS_IOMEM to the grcan
driver.

Michal Simek's patch for the xilinx driver add dev_err_probe()
support.

Arnd Bergmann's patch for the ucan driver fixes a compiler warning.

Stephane Grosjean provides 3 patches for the peak USB drivers, which
add ethtool set_phys_id and CAN one-shot mode.

Xulin Sun's patch removes a not needed return check in the m-can
driver. Torin Cooper-Bennun provides 3 patches for the m-can driver
that add rx-offload support to ensure that skbs are sent from softirq
context. Wan Jiabing's patch for the tcan4x5x driver removes a
duplicate include.

The next 6 patches are by me and target the mcp251xfd driver. They add
devcoredump support, simplify the UINC handling, and add HW timestamp
support.

The remaining 12 patches target the c_can driver. The first 6 are by
me and do generic checkpatch related cleanup work. Dario Binacchi's
patches bring some cleanups and increase the number of usable message
objects from 16 to 64.

regards,
Marc
