These are 5-port devices and are managed over an SPI 11 interface. Probing is handled based on OF bindings and so is the 12 linkage to PHYLINK. The driver supports the following revisions: 13 - SJA1105E (Gen. 1, No TT-Ethernet) 14 - SJA1105T (Gen. 1, TT-Ethernet) 15 - SJA1105P (Gen. 2, No SGMII, No TT-Ethernet) 16 - SJA1105Q (Gen. 2, No SGMII, TT-Ethernet) 17 - SJA1105R (Gen. 2, SGMII, No TT-Ethernet) 18 - SJA1105S (Gen. 2, SGMII, TT-Ethernet) 19 20config NET_DSA_SJA1105_PTP 21 bool "Support for the PTP clock on the NXP SJA1105 Ethernet switch" 22 depends on NET_DSA_SJA1105 23 help 24 This enables support for timestamping and PTP clock manipulations in 25 the SJA1105 DSA driver. 26 27config NET_DSA_SJA1105_TAS 28 bool "Support for the Time-Aware Scheduler on NXP SJA1105" 29 depends on NET_DSA_SJA1105 30 depends on NET_SCH_TAPRIO 31 help 32 This enables support for the TTEthernet-based egress scheduling 33 engine in the SJA1105 DSA driver, which is controlled using a 34 hardware offload of the tc-tqprio qdisc. 35
