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

Hello David,

this is a pull request of 17 patches for net-next/master.

The first 3 patches are by me and fix several warnings found when compiling the 
kernel with W=1.

Lukas Bulwahn's patch adjusts the MAINTAINERS file, to accommodate the renaming 
of the mcp251xfd driver.

Vincent Mailhol contributes 3 patches for the CAN networking layer. First error
queue support is added the the CAN RAW protocol. The second patch converts the
get_can_dlc() and get_canfd_dlc() in-Kernel-only macros from using __u8 to u8.
The third patch adds a helper function to calculate the length of one bit in in
multiple of time quanta.

Oliver Hartkopp's patch add support for the ISO 15765-2:2016 transport protocol
to the CAN stack.

Three patches by Lad Prabhakar add documentation for various new rcar
controllers to the device tree bindings of the rcar_can and rcan_canfd driver.

Michael Walle's patch adds various processors to the flexcan driver binding
documentation.

The next two patches are by me and target the flexcan driver aswell. The remove
the ack_grp and ack_bit from the fsl,stop-mode DT property and the driver, as
they are not used anymore. As these are the last two arguments this change will
not break existing device trees.

The last three patches are by Srinivas Neeli and target the xilinx_can driver.
The first one increases the lower limit for the bit rate prescaler to 2, the
other two fix sparse and coverity findings.

regards,
Marc
