Subject: [PATCH net 0/15] pull-request: can 2022-07-04

Hello Jakub, hello David,

this is a pull request of 15 patches for net/master.

The 1st patch is by Oliver Hartkopp, targets the BCM CAN protocol and
converts a costly synchronize_rcu() to call_rcu() to fix a performance

Srinivas Neeli's patch for the xilinx_can driver drops the brp limit
down to 1, as only the pre-production silicon have an issue with a brp
of 1.

The next patch is by Duy Nguyen and fixes the data transmission on
R-Car V3U SoCs in the rcar_canfd driver.

Rhett Aultman's patch fixes a DMA memory leak in the gs_usb driver.

Liang He's patch removes an extra of_node_get() in the grcan driver.

The next 2 patches are by me, target the m_can driver and fix the
timestamp handling used for peripheral devices like the tcan4x5x.

Jimmy Assarsson contributes 3 patches for the kvaser_usb driver and
fixes CAN clock and bit timing related issues.

The remaining 5 patches target the mcp251xfd driver. Thomas Kopp
contributes 2 patches to improve the workaround for broken CRC when
reading the TBC register. 3 patches by me add a missing
hrtimer_cancel() during the ndo_stop() callback, and fix the reading
of the Device ID register.
