Subject: [PATCH v3 0/3] can: xilinx_can: Add ECC feature support

Add ECC feature support to Tx and Rx FIFOs for Xilinx CAN Controller.
Part of this feature configuration and counter registers added in 
Xilinx AXI CAN Controller 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.
