Hello David,

this is a pull request of 13 patches for net-next.

The first 10 target the mcp25xxfd driver (which is renamed to mcp251xfd during
this series).

The first two patches are by Thomas Kopp, which adds reference to the just
related errata and updates the documentation and log messages.

Dan Carpenter's patch fixes a resource leak during ifdown.

A patch by me adds the missing initialization of a variable.

Oleksij Rempel updates the DT binding documentation as requested by Rob
Herring.

The next 5 patches are by Thomas Kopp and me. During review Geert Uytterhoeven
suggested to use "microchip,mcp251xfd" instead of "microchip,mcp25xxfd" as the
DT autodetection compatible to avoid clashes with future but incompatible
devices. We decided not only to rename the compatible but the whole driver from
"mcp25xxfd" to "mcp251xfd". This is done in several patches.

Joakim Zhang contributes three patches for the flexcan driver. The first one
adds support for the ECC feature, which is implemented on some modern IP cores,
by initializing the controller's memory during ifup. The next patch adds
support for the i.MX8MP (which supports ECC) and the last patch properly
disables the runtime PM if device registration fails.
