These are managed over an SPI 13 interface. Probing is handled based on OF bindings and so is the 14 linkage to PHYLINK. The driver supports the following revisions: 15 - SJA1105E (Gen. 1, No TT-Ethernet) 16 - SJA1105T (Gen. 1, TT-Ethernet) 17 - SJA1105P (Gen. 2, No SGMII, No TT-Ethernet) 18 - SJA1105Q (Gen. 2, No SGMII, TT-Ethernet) 19 - SJA1105R (Gen. 2, SGMII, No TT-Ethernet) 20 - SJA1105S (Gen. 2, SGMII, TT-Ethernet) 21 - SJA1110A (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 10 ports) 22 - SJA1110B (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 9 ports) 23 - SJA1110C (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 7 ports) 24 - SJA1110D (Gen. 3, SGMII, TT-Ethernet, no 100base-TX PHY, 7 ports) 25 26config NET_DSA_SJA1105_PTP 27 bool "Support for the PTP clock on the NXP SJA1105 Ethernet switch" 28 depends on NET_DSA_SJA1105 29 depends on PTP_1588_CLOCK 30 help 31 This enables support for timestamping and PTP clock manipulations in 32 the SJA1105 DSA driver. 33 34config NET_DSA_SJA1105_TAS 35 bool "Support for the Time-Aware Scheduler on NXP SJA1105" 36 depends on NET_DSA_SJA1105 && NET_SCH_TAPRIO 37 depends on NET_SCH_TAPRIO=y || NET_DSA_SJA1105=m 38 depends on NET_DSA_SJA1105_PTP 39 help 40 This enables support for the TTEthernet-based egress scheduling 41 engine in the SJA1105 DSA driver, which is controlled using a 42 hardware offload of the tc-tqprio qdisc. 43 44config NET_DSA_SJA1105_VL 45 bool "Support for Virtual Links on NXP SJA1105" 46 depends on NET_DSA_SJA1105_TAS 47 help 48 This enables support for flow classification using capable devices 49 (SJA1105T, SJA1105Q, SJA1105S).
