[PATCH net-next v2 03/10] net: ethernet: ti: netcp_ethss: add support for child cpts node

From: Grygorii Strashko
Date: Thu Jun 06 2019 - 12:35:44 EST


Allow to place CPTS properties in the child "cpts" DT node. For backward
compatibility - roll-back and read CPTS DT properties from parent node if
"cpts" node is not present.
