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)
