====================
pull-request: can-next 2020-12-10
here's a pull request of 7 patches for net-next/master.
The first patch is by Oliver Hartkopp for the CAN ISOTP, which adds support for
functional addressing.
A patch by Antonio Quartulli removes an unneeded unlikely() annotation from the
rx-offload helper.
The next three patches target the m_can driver. Sean Nyekjaers's patch removes
a double clearing of clock stop request bit, Patrik Flykt's patch moves the
runtime PM enable/disable to m_can_platform and Jarkko Nikula's patch adds a
PCI glue code driver.
Fabio Estevam's patch converts the flexcan driver to DT only.
And Manivannan Sadhasivam's patchd for the mcp251xfd driver adds internal
loopback mode support.
