Subject: [PATCH v8 0/3] Add ECC feature support to Tx and Rx FIFOs for
 Xilinx CAN Controller.

ECC is an IP configuration option where counter registers are added in
IP for 1bit/2bit ECC errors count and reset.

Also driver reports 1bit/2bit ECC errors for FIFOs based on ECC error
interrupts.

Add xlnx,has-ecc optional property for Xilinx AXI CAN controller
to support ECC if the ECC block is enabled in the HW.

Add ethtool stats interface for getting all the ECC errors information.

There is no public documentation for it available.

Changes in v8:
- Use u64_stats_sync instead of spinlock
- Renamed stats strings: use "_" instead of "-"
- Renamed stats strings: add "_errors" trailer
- Renamed stats variables similar to stats strings

Changes in v7:
- Update with spinlock only for stats counters

Changes in v6:
- Update commit description

Changes in v5:
- Fix review comments
- Change the sequence of updates the stats
- Add get_strings and get_sset_count stats interface
- Use u64 stats helper function

Changes in v4:
- Fix DT binding check warning
- Update xlnx,has-ecc property description

Changes in v3:
- Update mailing list
- Update commit description

Changes in v2:
- Address review comments
- Add ethtool stats interface
- Update commit description
