| 9 | This is the driver for the NXP SJA1105 automotive Ethernet switch | |
| 10 | family. These are 5-port devices and are managed over an SPI | |
| 11 | interface. Probing is handled based on OF bindings and so is the | |
| 1fd4a173 | 12 | linkage to PHYLINK. The driver supports the following revisions: |
| 8aa9ebcc VO |
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) | |
