Subject: [PATCH v8 1/3] dt-bindings: can: xilinx_can: Add 'xlnx,has-ecc'
 optional property

From: Srinivas Goud <srinivas.goud@....com>

ECC feature added to CAN TX_OL, TX_TL and RX FIFOs of Xilinx AXI CAN
Controller.

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

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