Subject: [PATCH v7 0/3] can: xilinx_can: Add ECC feature support

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.
