This patch add dt bindings to support network driver based on Network Sub System (NSS) found on k2g SoC. This consists of bindings for netcp node, nss qmss , pktdma, cpsw 2u version of ethss and mdio. In order to support transitioning between non-promiscuous and promiscuous modes in K2G's ethernet switch, netcp ALE needs to be enabled. Therefore this patch enables K2G's netcp ALE for that purpose.
