4 depends on NET_DSA && SPI
5 select NET_DSA_TAG_SJA1105
10 This is the driver for the NXP SJA1105 automotive Ethernet switch
11 family. These are 5-port devices and are managed over an SPI
12 interface. Probing is handled based on OF bindings and so is the
13 linkage to PHYLINK. The driver supports the following revisions:
14 - SJA1105E (Gen. 1, No TT-Ethernet)
15 - SJA1105T (Gen. 1, TT-Ethernet)
16 - SJA1105P (Gen. 2, No SGMII, No TT-Ethernet)
17 - SJA1105Q (Gen. 2, No SGMII, TT-Ethernet)
18 - SJA1105R (Gen. 2, SGMII, No TT-Ethernet)
19 - SJA1105S (Gen. 2, SGMII, TT-Ethernet)

23 depends on NET_DSA_SJA1105
24 depends on PTP_1588_CLOCK
26 This enables support for timestamping and PTP clock manipulations in
27 the SJA1105 DSA driver.

32 depends on NET_SCH_TAPRIO=y || NET_DSA_SJA1105=m
33 depends on NET_DSA_SJA1105_PTP
35 This enables support for the TTEthernet-based egress scheduling
36 engine in the SJA1105 DSA driver, which is controlled using a
37 hardware offload of the tc-tqprio qdisc.
39 config NET_DSA_SJA1105_VL
40 bool "Support for Virtual Links on NXP SJA1105"
41 depends on NET_DSA_SJA1105_TAS
43 This enables support for flow classification using capable devices
44 (SJA1105T, SJA1105Q, SJA1105S). The following actions are supported:
45 - redirect, trap, drop
46 - time-based ingress policing, via the tc-gate action
