Subject: [PATCH v2 0/3] can: xilinx_can: Add ECC feature support

Add ECC feature support to Tx and Rx FIFO’s for Xilinx CAN Controller.
Part of this feature configuration and counter registers added in 
Xilinx CAN Controller for 1bit/2bit ECC errors count and reset.
Also driver reports 1bit/2bit ECC errors for FIFO's based on 
ECC error interrupts.

xlnx,has-ecc is optional property and is added to Xilinx CAN Controller 
node if ECC block enabled in the HW.

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

There is no public documentation for it available.
