====================
pull-request: can-next 2020-09-21

this is a pull request of 38 patches for net-next.

the first 5 patches are by Colin Ian King, Alexandre Belloni and me and they
fix various spelling mistakes.

The next patch is by me and fixes the indention in the CAN raw protocol
according to the kernel coding style.

Diego Elio Pettenò contributes two patches to fix dead links in CAN's Kconfig.

Masahiro Yamada's patch removes the "WITH Linux-syscall-note" from SPDX tag of
C files.

AThe next 4 patches are by me and target the CAN device infrastructure and add
error propagation and improve the output of various messages to ease driver
development and debugging.

YueHaibing's patch for the c_can driver removes an unused inline function.

Next follows another patch by Colin Ian King, which removes the unneeded
initialization of a variable in the mcba_usb driver.

A patch by me annotates a fallthrough in the mscan driver.

The ti_hecc driver is converted to use devm_platform_ioremap_resource_byname()
in a patch by Dejin Zheng.

Liu Shixin's patch converts the pcan_usb_pro driver to make use of
le32_add_cpu() instead of open coding it.

Wang Hai's patch for the peak_pciefd_main driver removes an unused makro.

Vaibhav Gupta's patch converts the pch_can driver to generic power management.

Stephane Grosjean improves the pcan_usb usb driver by first documenting the
commands sent to the device and by adding support of rxerr/txerr counters.

The next patch is by me and cleans up the Kconfig of the CAN SPI drivers.

The next 6 patches all target the mcp251x driver, they are by Timo Schlüßler,
Andy Shevchenko, Tim Harvey and me. They update the DT bindings documentation,
sort the include files alphabetically, add GPIO support, make use of the
readx_poll_timeout() helper, and add support for half duplex SPI-controllers.

Wolfram Sang contributes a patch to update the contact email address in the
mscan driver, while Zhang Changzhong updates the clock handling.

The next patch is by and updates the rx-offload infrastructure to support
callback less usage.

The last 6 patches add support for the mcp25xxfd CAN SPI driver. First the
dt-bindings are added by Oleksij Rempel, the regmap infrastructure and the main
driver is contributed by me. Kurt Van Dijck adds listen-only support,
Manivannan Sadhasivam adds himself as maintainer, and Thomas Kopp himself as a
reviewer.
