	  This is the driver for the NXP SJA1105 (5-port) and SJA1110 (10-port)
	  automotive Ethernet switch family. These 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)
	    - SJA1110A (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 10 ports)
	    - SJA1110B (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 9 ports)
	    - SJA1110C (Gen. 3, SGMII, TT-Ethernet, 100base-TX PHY, 7 ports)
	    - SJA1110D (Gen. 3, SGMII, TT-Ethernet, no 100base-TX PHY, 7 ports)

	depends on NET_DSA_SJA1105
	depends on PTP_1588_CLOCK
	help
	  This enables support for timestamping and PTP clock manipulations in
	  the SJA1105 DSA driver.

	depends on NET_DSA_SJA1105_PTP
	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.

config NET_DSA_SJA1105_VL
	bool "Support for Virtual Links on NXP SJA1105"
	depends on NET_DSA_SJA1105_TAS
	help
	  This enables support for flow classification using capable devices
	  (SJA1105T, SJA1105Q, SJA1105S). The following actions are supported:
	  - redirect, trap, drop
	  - time-based ingress policing, via the tc-gate action
