help
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)

help
This enables support for timestamping and PTP clock manipulations in
the SJA1105 DSA driver.

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