46  * @vops: Router vendor specific NVM operations (optional)
96  * struct tb_switch_tmu - Structure holding router TMU configuration
99  * @mode: TMU mode related to the upstream router. Reflects the HW
100  *	  setting. Don't care for host router.
101  * @mode_request: TMU mode requested to set. Related to upstream router.
102  *		   Don't care for host router.
156  * @max_usb3_credits: Router preferred number of buffers for USB 3.x
157  * @min_dp_aux_credits: Router preferred minimum number of buffers for DP AUX
158  * @min_dp_main_credits: Router preferred minimum number of buffers for DP MAIN
159  * @max_pcie_credits: Router preferred number of buffers for PCIe
160  * @max_dma_credits: Router preferred number of buffers for DMA/P2P
161  * @clx: CLx states on the upstream link of the router
166  * In USB4 terminology this structure represents a router.
316  * @index: Retimer index facing the router USB4 port
431  * Support paths from the farthest (depth 6) router to the host and back
432  * to the same level (not necessarily to the same router).
475  * @usb4_switch_op: Optional proxy for USB4 router operations. If set
476  *		    this will be called whenever USB4 router operation is
478  *		    native USB4 router operation is called.
482  *					 router operation.
853  * tb_switch_downstream_port() - Return downstream facing port of parent router
854  * @sw: Device router pointer
857  * the parent router.
867  * tb_switch_depth() - Returns depth of the connected router
868  * @sw: Router
983  * @sw: Router whose mode to check
986  * Checks if given router TMU mode is configured to @mode. Note the
987  * router TMU might not be enabled to this mode.
997  * @sw: Router whose TMU mode to check
1017  * @sw: Router to check for the CLx
1020  * Checks if the specified CLx is enabled on the router upstream link.
1023  * Not applicable for a host router.
1212  * tb_xdomain_downstream_port() - Return downstream facing port of parent router
1240  * usb4_switch_version() - Returns USB4 version of the router
1241  * @sw: Router to check
1243  * Returns major version of USB4 router (%1 for v1, %2 for v2 and so
1244  * on). Can be called to pre-USB4 router too and in that case returns %0.
1255  * Returns true if the @sw is USB4 compliant router, false otherwise.
