config PLATFORM_EC_USBC_RETIMER_INTEL_BB
	bool "Support Intel Burnside Bridge retimer"
	help
	  Enable this to support the Intel Burnside Bridge Thunderbolt / USB /
	  DisplayPort retimer.

	  Intel Burnside Bridge is a Type-C multi-protocol retimer to be used
	  in on-board applications. Burnside Bridge offers the ability to latch
	  protocol signals into on-chip memory before retransmitting them
	  onwards. It can be used to extend the physical length of the system
	  without increasing high-frequency jitter.

	  Burnside Bridge supports spec compliant retimer of following
	  protocols:

	    - Display Port: four unidirectional DP lanes
	    - USB3.1 Gen1/2: one bi-directional USB lane
	    - Thunderbolt: two bi-directional CIO lanes
	    - Multifunction Display (MFD): two unidirectional lanes of DP and
	      one bidirectional lane of USB3.1 Gen1/2

	bool "Support Intel Hayden Bridge retimer"
	help
	  Enable this to support the Intel Hayden Bridge Thunderbolt / USB /
	  DisplayPort retimer.

	  Intel Hayden Bridge is a Type-C multi-protocol retimer to be used
	  in on-board applications. Hayden Bridge offers the ability to latch
	  protocol signals into on-chip memory before retransmitting them
	  onwards. It can be used to extend the physical length of the system
	  without increasing high-frequency jitter.

	  Hayden Bridge supports spec compliant retimer of following
	  protocols:
	  - Display Port: four unidirectional DP lanes
	  - USB3.2 Gen1/2: two bi-directional USB lanes
	  - Thunderbolt/USB4: two bi-directional USB4 lanes
	  - Multifunction Display (MFD): two unidirectional lanes of DP and
	    one bi-directional lane of USB3.2 Gen1/2

config PLATFORM_EC_USBC_RETIMER_INTEL_BB_RUNTIME_CONFIG
	bool "Use runtime configuration of Intel Burnside Bridge"
	depends on PLATFORM_EC_USBC_RETIMER_INTEL_BB
	default y
	help
	  Enable this to allow run-time configuration of the Burnside Bridge
	  driver structure. This makes the bb_controls[] array writable, i.e.
	  not const. It should be declared as such in the board config.

	  This is useful when the board has runtime information that changes
	  the configuration, such as Chromium OS Board Info (CBI set in the
	  factory. Without this, multiple EC images would need to be installed
	  depending on the board.

config PLATFORM_EC_USBC_RETIMER_INTEL_BB_VPRO_CAPABLE
	bool "Enable vPro support for Intel Burnside Bridge"
	depends on PLATFORM_EC_USBC_RETIMER_INTEL_BB
	default n
	help
	  Enable this config for Intel vPro supported platforms. It allows to
	  configure the Burnside Bridge retimer to support vPro, when connected
	  dock supports vPro.

config PLATFORM_EC_USBC_RETIMER_ANX7451
	bool "Support Analogix ANX7451 10G Active Mux and Retimer"
	help
	  ANX7451 is a 4x4 re-timing mux capable of switching DisplayPort (DP)
	  and USB3.2 Gen 2 10Gbps signals to support a single USB Type-C port.
	  ANX7451 has built-in re-timers to recover both the USB and DP signals
	  with loss compensation of 23dB for USB and up to 27dB for DP.

config PLATFORM_EC_USBC_RETIMER_ANX7483
	bool "Support Analogix ANX7483 10G Active Retimer"
	help
	  ANX7483 is a 4x4 re-driver capable of switching DisplayPort and
	  USB3.2 Gen 2 10Gbps signals to support type-C (USB-C) ports with
	  DisplayPort Alternate Mode.

config PLATFORM_EC_USBC_RETIMER_PS8811
	bool "Support Parade PS8811 Single Port USB 3.1 Gen 2 10G Retimer"
	help
	  The PS8811 is a one-port bidirectional USB 3.1 Gen 2 retimer that
	  integrates the UniEye equalizer and a retimer to re-condition USB 3.1
	  signals for long media link applications. It supports USB 3.1 Gen 2
	  with operation speed up to 10Gbps as well as Gen 1 operation at 5Gbps.

config PLATFORM_EC_USBC_RETIMER_PS8818
	bool "Parade PS8818 USB Type-C Retimer for USB and DP Alternate Mode"
	help
	  PS8818 is a 10Gbps retimer for Type-C applications with the
	  integrated USB3.1 and DisplayPort alternate mode port.
