Hello Jakub, hello David,
this is a pull request of 36 patches for net-next/master.
The first 5 patches are by me and update various CAN DT bindings.
Eric Dumazet's patch for the CAN GW replaces a costly
synchronize_rcu() by a call_rcu().
The next 2 patches by me enhance the CAN bit rate handling, the bit
rate checking is simplified and the arguments and local variables of
functions are marked as const.
A patch by me for the kvaser_usb driver removes a redundant variable.
The next patch by me lets the c_can driver use the default ethtool
drvinfo.
Minghao Chi's patch for the softing driver removes a redundant
variable.
Srinivas Neeli contributes an enhancement for the xilinx_can NAPI poll
function.
Vincent Mailhol's patch for the etas_es58x driver converts to
BITS_PER_TYPE() from of manual calculation.
The next 23 patches target the mcp251xfd driver and are by me. The
first 15 patches, add support for the internal PLL, which includes
simplifying runtime PM handling, better chip detection and error
handling after wakeup, and the PLL handling. The last 8 patches
prepare the driver to support multiple RX-FIFOs and runtime
configurable RX/TX rings. The actual runtime ring configuration via
ethtool will be added in a later patch series.
regards,
Marc
