====================
pull-request: can-next 2022-06-25

this is a pull request of 22 patches for net-next/master.

The first 2 patches target the xilinx driver. Srinivas Neeli's patch
adds Transmitter Delay Compensation (TDC) support, a patch by me fixes
a typo.

The next patch is by me and fixes a typo in the m_can driver.

Another patch by me allows the configuration of fixed bit rates
without need for do_set_bittiming callback.

The following 7 patches are by Vincent Mailhol and refactor the
can-dev module and Kbuild, de-inline the can_dropped_invalid_skb()
function, which has grown over the time, and drop outgoing skbs if the
controller is in listen only mode.

Max Staudt's patch fixes a reference in the networking/can.rst
documentation.

Vincent Mailhol provides 2 patches with cleanups for the etas_es58x
driver.

Conor Dooley adds bindings for the mpfs-can to the PolarFire SoC dtsi.

Another patch by me allows the configuration of fixed data bit rates
without need for do_set_data_bittiming callback.

The last 5 patches are by Frank Jungclaus. They prepare the esd_usb
driver to add support for the the CAN-USB/3 device in a later series.
