Subject: [PATCH v2 0/3] can: ctucanfd: hardware rx timestamps reporting

Hello,

this is the v2 patch for CTU CAN FD hardware timestamps reporting.

This patch series is based on the latest net-next, as I need the patch
- 9e7c9b8eb719 can: ctucanfd: Update CTU CAN FD IP core registers to match version 3.x.
and the patch below to avoid git conflict (both this and my patch
introduce ethtool_ops)
- 409c188c57cd can: tree-wide: advertise software timestamping capabilities

Changes in v2: (compared to the RFC I've sent in May)
- Removed kconfig option to enable/disable timestamps.
- Removed dt parameters ts-frequency and ts-used-bits. Now the user
  only needs to add the timestamping clock phandle to clocks, and even
  that is optional.
- Added SIOCSHWTSTAMP ioctl to enable/disable timestamps.
- Adressed comments from the RFC review.

Matej Vasilevski (3):
  can: ctucanfd: add HW timestamps to RX and error CAN frames
  dt-bindings: can: ctucanfd: add another clock for HW timestamping
  doc: ctucanfd: RX frames timestamping for platform devices
