This is the driver for the NXP SJA1105 (5-port) and SJA1110 (10-port)
automotive Ethernet switch family. These are managed over an SPI
interface. Probing is handled based on OF bindings and so is the
linkage to PHYLINK. The driver supports the following revisions:
- SJA1105E (Gen. 1, No TT-Ethernet)
- SJA1105T (Gen. 1, TT-Ethernet)
- SJA1105P (Gen. 2, No SGMII, No TT-Ethernet)
- SJA1105Q (Gen. 2, No SGMII, TT-Ethernet)
- SJA1105R (Gen. 2, SGMII, No TT-Ethernet)
- SJA1105S (Gen. 2, SGMII, TT-Ethernet)
- SJA1110A (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 10 ports)
- SJA1110B (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 9 ports)
- SJA1110C (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 7 ports)
- SJA1110D (Gen. 3, SGMII, TT-Ethernet, no 100base-TX PHY, 7 ports)
