These are 5-port devices and are managed over an SPI 118aa9ebccSVladimir Oltean interface. Probing is handled based on OF bindings and so is the 121fd4a173SVladimir Oltean linkage to PHYLINK. The driver supports the following revisions: 138aa9ebccSVladimir Oltean - SJA1105E (Gen. 1, No TT-Ethernet) 148aa9ebccSVladimir Oltean - SJA1105T (Gen. 1, TT-Ethernet) 158aa9ebccSVladimir Oltean - SJA1105P (Gen. 2, No SGMII, No TT-Ethernet) 168aa9ebccSVladimir Oltean - SJA1105Q (Gen. 2, No SGMII, TT-Ethernet) 178aa9ebccSVladimir Oltean - SJA1105R (Gen. 2, SGMII, No TT-Ethernet) 188aa9ebccSVladimir Oltean - SJA1105S (Gen. 2, SGMII, TT-Ethernet) 19bb77f36aSVladimir Oltean 20bb77f36aSVladimir Olteanconfig NET_DSA_SJA1105_PTP 21*78fe8a28SArnd Bergmann bool "Support for the PTP clock on the NXP SJA1105 Ethernet switch" 22bb77f36aSVladimir Oltean depends on NET_DSA_SJA1105 23bb77f36aSVladimir Oltean help 24bb77f36aSVladimir Oltean This enables support for timestamping and PTP clock manipulations in 25bb77f36aSVladimir Oltean the SJA1105 DSA driver. 26
