| This is the driver for the NXP SJA1105 automotive Ethernet switch |
| family. These are 5-port devices and 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) |
