   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
  12           linkage to PHYLINK. The driver supports the following revisions:
  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)

  34           This enables support for the TTEthernet-based egress scheduling
  35           engine in the SJA1105 DSA driver, which is controlled using a
  36           hardware offload of the tc-tqprio qdisc.
